Suppressor of cytokine signalling (SOCS) proteins induced by STAT signal transduction feed back to regulate STAT signalling negatively. The JAK/STAT/SOCS pathway is depicted in Fig. 2. The IL-2-induced JAK3/STAT5 pathway is an indispensible signal transduction mechanism for the direct induction of FOXP3 in Tregs[115],

as animals deficient in IL-2, IL-2Rα (CD25), IL-2Rβ (CD122) or STAT5 have depleted numbers of Tregs, fail to express FoxP3 and develop autoimmune diseases find more [115–118]. In these models, animals can be rescued from autoimmunity with restored Treg development if IL-2 signalling is re-established, for example, by reconstitution with bone marrow from an IL-2Rβ mutant that activates STAT5 exclusively or by ectopic activation of foxp3 in CD4+ T cells [116]. Similarly, STAT5 deficiency in humans results in loss of Tregs and immune dysregulation, while overexpression of STAT5 in CD4+CD25- cells leads to elevated levels of FoxP3 [119,120]. These observations can be explained by

the direct binding of STAT5 to the foxp3 promoter [115,116], instigating an IL-2-directed STAT5-dependent positive regulation of foxp3. Indeed, Tregs show an obligate requirement, both in vivo and in vitro, for IL-2 and the structurally related IL-2 family members, IL-15 and IL-7, for maintenance of FoxP3 expression and suppressive function [119,121–123]. Th17 development BMN 673 mw from naive precursors is dependent upon selleck chemicals llc signal transduction through STAT3. In mice, RORC is a STAT3 target gene and Th17 differentiation is induced by STAT3 signalling cytokines, notably IL-6, IL-21 and IL-23,

and can be abrogated effectively by a deficiency in STAT3 [124]. In humans, STAT3 deficiency from dominant negative mutations in the STAT3 gene occurs in the hyperIgE (HIES or Job) syndrome (OMIM 147060), which is characterized by morphological abnormalities, recurrent infections (particularly with Staphylococcus aureus and Candida sp.) and a deficiency of Th17 cells [59,125–127]. Patients with HIES not only have reduced Th17 numbers, but their naive Th cells are resistant to Th17 differentiation under appropriate stimulatory conditions, with concomitant impairment of RORγt expression relative to healthy controls [59,126]. There are reasons to suspect that the STAT3/STAT5 signalling pathways are important in the conversion of Tregs to Th17. First, there is evidence to suggest that STAT5 and STAT3 cross-regulate the conversion of naive T cells to the Treg and Th17 lineages. Specifically, in mice, IL-2-induced STAT5 inhibits Th17 differentiation from IL-6 and TGF-β stimulated naive Th cells [128]. It should be noted that, although this inhibition is STAT5-dependent, it is unclear whether the mechanism is a direct STAT5 inhibition of IL-17 associated genes or an indirect effect of STAT5-induced FoxP3-directed inhibition of Th17 transcription factors (as described above).

TNF polymorphism rs1800630 A-allele was associated with lower specific anti-pneumococcal IgG levels compared with children carrying C/C genotype of rs1800630. Typhoid fever.  Typhoid fever is caused by Salmonella enterica infection with serotype Typhi and 22 million cases of typhoid fever occur worldwide per year, resulting in 200,000 deaths. Indonesian study suggested a protective role of DRB1*12021 for complicated typhoid fever. Keuter et al. [43] found www.selleckchem.com/products/epz-6438.html a lower level of TNF-α in the patients with acute phase of typhoid fever than in convalescence. The seven polymorphisms have been found within the genes BAT1 (a member of the DEAD-box

protein family encoding an ATP-dependent RNA helicase and a negative regulator of inflammation), LTA and TNF. All three genes, or haplotypes spanning these genes, have been associated with a variety of infectious and inflammatory diseases. Dunstan et al. [44] genotyped eighty SNPs in a region of 150 kb in Vietnamese individuals.

Thirty-three SNPs with a minor allele frequency of greater than 4.3% were used to construct haplotypes. Fifteen SNPs which tagged the 42 constructed haplotypes were selected. The haplotype-tagging SNPs (T1–T15) were genotyped, and allelic frequencies of seven SNPs (T1, T2, T3, T5, T6, T7 and T8) have shown a significant difference between typhoid cases and controls. Haplotype-based analysis of the tag SNPs provided positive evidence of association Angiogenesis inhibitor with typhoid. The analysis detected a low-risk cluster of haplotypes that each carries the minor allele of T1 or T7, but not both, and otherwise carries the combination of alleles *12122*1111 at T1–T11. Individuals who carry the typhoid fever–protective haplotype *12122*1111 also produce a relatively low TNF-α response to LPS. Severe sepsis in trauma patients.  In the non-coronary intensive care unit, sepsis is the prevalent cause of death. A restriction fragment length polymorphism (RFLP) present in TNF gene is correlated

with increased level of TNF-α in plasma and a high mortality rate in patients with severe sepsis. This non-synonimous polymorphism in the first intron of the TNF-β gene (1064–1069 position) is responsible crotamiton for an amino acid change at position 26 (asparagine for the TNFB1 sequence and threonine for the TNFB2 sequence) [45]. Previously, the mortality rate in severe sepsis was found to be significantly increased in patients homozygous for the allele TNFB2 of the Nco1 polymorphism compared with heterozygous patients [46]. A statistically highly significant association was obtained between the genotype of the biallelic Nco1 polymorphism of the TNF β gene and the development of severe sepsis after severe blunt trauma. Subjects homozygous for the allele TNFB2 have a significantly increased risk of the development of severe post-traumatic sepsis.

On pathology, adults had more outstanding chronic changes by light microscopy and more untypical staining by immunofluorescence. “
“Date written: August 2008 Final submission: April 2009 No recommendations possible based on Level I or II evidence Potential living kidney donors should have their

blood pressure (BP) measured on at least three occasions with a level less than 140/90 mmHg on all three occasions. Short- and long-term live donor outcomes need to be closely monitored. The aim of this guideline is to review the available literature in relation to live donor effects on BP and in the setting of pre-existing hypertension in the living donor. In particular, the following issues need to be considered: (i)  the effect of unilateral nephrectomy on BP in healthy, normotensive individuals, and Hypertension is a common disorder that is often found incidentally on routine medical examination. In many individuals, it has often been present for several learn more years before it is eventually diagnosed. Even when considering a clearly normotensive individual, one must still consider the lifetime risk of developing hypertension in that individual. An additional factor to consider is that BP is known to rise with ageing. The definition of hypertension has changed over time with the acceptable ‘treatable limits’ gradually falling over the past few decades. In addition,

it is now accepted that the relationship between BP and BMN 673 nmr cardiovascular risk does not have an absolute cut-off.1 The risk is continuous and is apparent in the normal range of BP (i.e. subjects with

a higher normal BP have an increased cardiovascular risk compared with those with a lower normal BP. As an example, the cardiovascular risk is higher for a subject with a normal BP of 135/80 mmHg, when compared with an age- and gender-matched individual with a BP of 115/70 mmHg). Individuals with hypertension or on antihypertensive therapy have been commonly excluded as kidney donors in the past. As a result, there is relatively little information available regarding the Venetoclax effects of donation on the long-term outcome in this group of live donors. At the present time due to a lack of appropriate data, it is difficult to clearly present conclusive information regarding the long-term effects of kidney donation in hypertensive individuals. In practice, it is generally accepted that kidney donation is contraindicated in those with hypertensive end-organ damage, poorly controlled hypertension and hypertension that requires multiple medications to achieve adequate control. Many units accept kidney donors with well-controlled hypertension and without any evidence of end-organ damage but other factors such as the donor’s age and other medical factors are usually considered simultaneously. On the basis that uninephrectomy may increase BP some units choose to completely exclude hypertensive individuals even when their BP is well controlled on minimal medication.

Of the main types of NK inhibitory receptors, the killer inhibitory receptor (KIR) family exhibits a restricted pattern of expression and selleck compound interact with only a limited subset of MHC class I ligands [83,84]. Nevertheless, inheritance of specific KIR alleles has profound implications for individual susceptibility to infectious diseases [85,86]. As shown in Table 3, the KIR3DL1/S1 locus has been associated with both slow progression to AIDS and resistance to HIV-1 infection. Inheritance of protective KIR3DL1high receptor alleles that lead to high cell surface expression and greater NK licensing were

observed to be over-represented in a high-risk cohort of HESN i.v. drug users from Montreal compared to HIV-1-infected subjects from the same geographic area (68·3% compared to 57·0%, respectively) [28]. KIR3DS1, an activating allele of the same KIR3DL1 locus, was also identified to be enriched in HESN subjects within the same Montreal this website cohort (13·8% compared to 5·3%, respectively) [17]. A smaller study of high-risk HESN female sex workers

from the Ivory Coast found no such association [2], although this latter finding is limited by the low frequency of the KIR3DS1 allele in African populations compared to Caucasians [87]. In support of a functional link with these protective alleles, NK cells expressing KIR3DS1 have been shown to produce more interferon (IFN)-γ[88] and mediate stronger inhibition of HIV-1 replication [89]. Additional evidence for the protective role of

NK cells in resistance to HIV-1 stems from a genetic study linking variants in non-classical MHC class I HLA-E and HLA-G molecules with reduced susceptibility to heterosexual acquisition of HIV-1 Gemcitabine cost [90]. Among the NK inhibitory receptors, the CD94/NKG2A receptor complex is unique in that it interacts specifically with the non-classical MHC protein, HLA-E, which presents leader peptides from the other classical MHC class I HLA-A, B, C molecules [83,84]. Inheritance of the HLA-E*0103 genetic variant, which leads to increased surface expression of HLA-E proteins and heightened NK surveillance of virally infected cells that down-regulate MHC class 1 proteins, was associated with a decreased risk of human immunodeficiency virus 1 (HIV-1) infection in Zimbabwean women [90]. Similarly, women carrying the HLA-G*0105N genotype, resulting in a null HLA-G inhibitory protein that cannot inhibit NK cells, also have a significantly decreased risk of HIV-1 infection [90]. While these genetic data suggest that NK stimulatory alleles are associated with protection from infection in some HESN subjects, a good number of HESN subjects lack these protective alleles.

With the next set of experiments we addressed the question whether surface IgE-positive B cells can be detected in IgE knock-in mice. First, we stimulated total spleen cells for 5 days with LPS and IL-4. We used IgE knock-in mice on the CD23−/− background in order to avoid passive binding of soluble Panobinostat research buy IgE to the low

affinity IgE receptor (CD23) on B cells [23]. Surface IgE and IgG1 were detected by flow cytometry. LPS alone neither induced significant IgE nor IgG1 expression (0.4–1.5%) (Fig. 2A and Supporting Information Fig. 1). In B cells from WT mice LPS+IL-4 induces IgG1 (23%), but only very little IgE (1.5%). In contrast, both cells isolated from either heterozygous or homozygous IgE knock-in mice express comparably high amounts of IgE (ca. 15%) on the cell surface. However, the Daporinad nmr small fraction of positively stained cells might be due to a cross-reactivity or background staining of

the detection antibodies (see also Fig. 2E). WT mice express 23% and heterozygous IgE knock-in mice 10% IgG1 and, as predicted, no IgG1 was found in IgEki/ki mice. These results suggest that in vitro the chimeric membrane IgE molecule can be transported to the surface with a slightly lower efficiency than natural IgG1. To confirm these results, we performed a RT-PCR analysis of the membrane forms of IgE, IgG1, and the chimeric membrane IgG1-IgE form (Fig. 2B). The results of LPS+IL-4 stimulated cultures are in line with the protein expression data (Fig. 2A); however, LPS alone induces mRNA transcripts with little IgG1 or chimeric IgE being expressed on the surface of the cells (Fig. 2B). Second, we analyzed B cells from bone marrow, lymph nodes (data not shown), and spleens of heterozygous IgE knock-in mice and their WT littermates. We could find a normal B-cell subset distribution in vivo (data not shown). However, we could not detect membrane IgE-positive B cells (Fig. 2C) in the

spleen. The absence of CD23 demonstrates that the increase in IgE expression is not a result of an increase in membrane IgE expressing B cells in unchallenged, naïve mice (Fig. 2C) [23]. Additionally, immunization and boost with the T-dependent antigen this website trinitro-phenyl-chicken ovalbumin (TNP-OVA) and the subsequent immunohistochemical analysis of splenic B-cell follicles shows only very rare IgE-positive cells located at the edge of the B-cell follicle in IgE knock-in mice of the CD23−/− background (Fig. 2D). Surface IgE and IgG1 expression in vivo were then analyzed after infection with the helminth Nippostrongyus brasiliensis (Nb), which leads to pronounced Th-2 responses [29]. Mesenteric lymph nodes of IgEki/ki, IgEki/wt, and WT mice were taken at day 14 after infection, at the peak of the germinal center response. IgEki/ki mice, as expected, showed no staining for IgG1, whereas IgEki/wt had intermediate expression of surface IgG1 when compared to WT.

This controls for the effect of diluting the level of antibodies when adding DTT to the reaction. Hence, if the crossmatch becomes negative with the addition of phosphate-buffered saline, the results with DTT cannot be fully interpreted as the result may have become negative by diluting the antibody level. Complement-dependent cytotoxicity crossmatching was

pioneered by Terasaki and colleagues in the 1960s.3,8 It seeks to identify clinically significant donor specific HLA antibody mediated responses for a given recipient. Lymphocytes from the donor are isolated and separated into T and B cells. Serum from the recipient is mixed with the lymphocytes in a multi-well plate. Complement is then added (usually derived from rabbit serum). If donor-specific antibody is present and binds to donor cells, the complement cascade will be activated via the classical selleck chemicals pathway resulting

in lysis of the lymphocytes (see Fig. 1). The read-out of the test is the percentage of dead cells relative to live cells as determined by microscopy. The result can thus be scored on the percentage of dead cells, with 0 correlating to no dead cells; scores of 2, 4 and 6 represent increasing levels of lysis. On this basis, a score of 2 is positive at a low level, consistent with approximately 20% lysis (generally taken as the cut-off for a positive result). A score of 8 represents all cells having lysed and

indicates the strongest possible reaction. The buy GSK3235025 use of a scoring system allows a semi-quantitative analysis of the strength of reaction. Another way to determine the strength of the reaction is to repeat the crossmatch using serial doubling dilutions of the recipient serum (often known as a ‘titred crossmatch’). In this way, dilutions are usually performed to 1 in 2, 4, 8, 16, 32, 64 and so on. In the situation of a high titre of high avidity DSAb it may be that many dilutions are required for the test to become negative (e.g. 1 in 128). With antibody at a low level or one with a low affinity, a single dilution may be enough to render the crossmatch result negative. This may also give an indication as to the likelihood that a negative crossmatch could be achieved Farnesyltransferase with a desensitization protocol. The basic CDC crossmatch can be enhanced by the addition of antihuman globulin (AHG). This technique increases the sensitivity of the CDC crossmatch as a result of multiple AHG molecules binding to each DSAb attached to the donor cells thereby amplifying the total number of Fc receptors available for interaction with complement component 1, which increases the likelihood of complement activation and cell lysis. In Australia this assay is not routinely used. It is also possible to have a negative crossmatch in the presence of a DSAb.

3E). These data indicated that the activated phenotype of NK cells was determined by MHC class I down-regulation

rather than by NKG2D-L levels expressed on early-stage tumors. Nevertheless, the higher MHC class I and lower NKG2D-L expression levels found in late tumor stages suggested that both, MHC class I SAHA HDAC manufacturer recovery and loss of NKG2D-L, may provide mechanisms of immune escape. To directly test the role of NKG2D-L loss in immune escape, we established cell lines from lymphoma-bearing mice with reduced MHC class I expression and selected variants with different NKG2D-L levels. Cell line myc-E showed background levels of NKG2D-L. In contrast, cell line myc-B had a 20-fold enhanced expression of NKG2D-L (Fig. 4A). After transfer into naïve WT mice, the myc-B line grew out slowly www.selleckchem.com/products/nu7441.html and was even rejected in 50% of the animals. In contrast, all mice injected with myc-E cells rapidly succumbed to tumor growth (Fig. 4B). Importantly, when NKG2D-L on myc-B cells were blocked with NKG2D multimers

prior to injection, protection was lost, and mice died as rapidly as those receiving the myc-E line. Protection against myc-B was also abrogated by NK-cell depletion (Fig. 4B). The data show that in these cell lines showing low MHC class I levels, expression of NKG2D-L is a signal that is required for NK cell-mediated elimination of tumor cells. To test the hypothesis that tumor escape from NK-cell surveillance results from re-expression of MHC class I and from suppression of NKG2D-L, we analyzed the outgrowing lymphomas in mice having received cell line myc-B. Indeed, the tumor cells that grew out after challenge with MHC

class Ilow/NKG2D-Lhigh myc-B cells were converted to MHC class Ihigh/NKG2D-Llow cells (Fig. 4C). NK cells isolated upon growth of myc-B also showed an activated status and decreased NKG2D expression (data not shown). The data demonstrate that tumor progression is not only due to exhaustion or paralysis of NK cells following their initial activation, as described above. In addition, loss of NKG2D-L as well as recovery of MHC class I on tumor cells contribute to escape from NK-cell surveillance. Protection from NK-cell attack and the NKG2D modulation observed on NK cells from tumor-bearing mice C59 might be an effect of NKG2D-L shedded from tumor cells. In two different assay systems (See the Materials and methods section), there was no evidence for the presence of soluble NKG2D-L in sera from tumor mice (Supporting Information), but a clear NKG2D down-regulation was seen when WT NK cells were incubated with ligand-expressing lymphoma cells in vitro (Fig. 4D). If NKG2D-L expression is needed for tumor elimination (Fig. 4B, C) although it was not correlated with the expression of NK-cell activation markers (Fig.

The mean diameter of lymphatic vessel used for LVA was 0.240 ± 0.057 mm, and the mean diameter of vein was 0.370 ± 0.146 mm. All lymphatic

vessels were translucent and very thin like human intact lymphatic vessels. In LVA group, intra- and post-operative anastomosis patency rates were 100% (10/10) based on ICG lymphography. In control group, intra- and post-operative patency rates were 0% (0/10). Conclusions: Rat lymphatic vessels are thin, translucent, and fragile similar to intact human lymphatic vessels. The LVA model uses easily accessible lymphatic vessels in the thigh, and is useful for training of supermicrosurgical LDK378 molecular weight LVA. © 2014 Wiley Periodicals, Inc. Microsurgery, 2014. “
“Peripheral nerve repair requires comprehensive evaluation selleck kinase inhibitor of functional outcomes of nerve regeneration; however, autonomic nerve function is seldom evaluated probably due to lack of suitable quantitative methods. This study sought to determine whether autonomic functional recovery could be reflected by cold-induced vasodilation (CIVD) within target skin territory, as monitored by laser Doppler perfusion imaging (LDPI). Rats with sciatic nerve defect injury received autologous nerve grafting, and the plantar surface of the hind feet was subjected to LDPI analysis following nerve repair.

The results indicated that at 3 and 6 months after autologous nerve grafting, the plantar surface of the hind foot exhibited the same level of CIVD as contralateral normal side,

whereas rats in nerve defect group (negative control) showed significantly reduced CIVD. In addition, suitable nerve regeneration and functional recovery were achieved as assessed by pain sensation tests as well as electrophysiological and immunohistological examinations. Based on the potential influence of local autonomic nerve signals on CIVD, it was possible to evaluate functional recovery of autonomic nerves by using LDPI measurements of dermal CIVD. © 2012 Wiley Periodicals, Inc.

“The groin lymph node flap transfer has been used for treatment of extremity lymphedema. The design of this flap is based on the superficial circumflex Alanine-glyoxylate transaminase iliac artery/vein (SCIA/V), or superficial inferior epigastric artery/vein (SIEA/V). The purpose of this study is to delineate the distribution of lymph nodes in the groin area and their relationship to inguinal vessels by the use of multidirector-row CT angiography (MDCTA). MDCTA was performed in 52 patients who underwent the deep inferior epigastric perforator (DIEP) flap or transverse rectus abdominis musculocutaneous (TRAM) flap for breast reconstruction. The MDCTA data were used to analyze the locations of lymph nodes and their adjacent vascular vessels. The groin region was divided into the superior lateral (I), superior medial (II), inferior lateral (III), and inferior medial (IV) quadrants based on the point where SCIV joined into great saphenous vein.

Histological examination

of a biopsy specimen from the leg lesions confirmed the diagnosis. The source of infection was an Ethiopian carer who had tinea capitis in the first case, and was undiagnosed in the second patient. Cases of purpuric variants of tinea corporis are rare and this is the first report of probable self-inoculation of T. violaceum from onychomycosis. “
“Fusarium species are actually the second most common pathogenic mould in immunocompromised patients, and it is difficult to treat such fusarial infections with current antifungal agents. We report the case of a 53-year-old woman with Philadelphia-positive acute lymphoblastic leukaemia. During induction chemotherapy with febrile neutropenia, check details she developed a disseminated fusariosis, with persistent fever refractory to antibacterial agents and caspofungin (as empirical therapy), painful skin lesions and respiratory impairment. Fusarium solani was isolated from skin biopsy. Voriconazole was successfully implemented as antifungal curative therapy. During the second intensive chemotherapy no reactivation of fusariosis was detected. “
“Oropharyngeal candidiasis (OPC) is a common infection among the

immuno-compromised population. Treatments include both systemic azoles, most commonly fluconazole (FLU), and topical agents such as miconazole (MICON). However, resistance click here to FLU has been reported with a greater frequency. The aim of this study was to determine the potential for development of resistance following repeated exposure of Candida spp. to MICON. Two clinical isolates each of Candida albicans, C. glabrata, and Venetoclax cell line C. tropicalis were tested. Fifteen passages of each strain were performed in concentrations of MICON at 0.5

minimum inhibitory concentration (MIC), 1 MIC, 2 MIC and 4 MIC, with MIC determinations performed on growth obtained following each passage. There was no increase in the MIC of four of the six strains following fifteen passages in MICON. One C. albicans strain demonstrated a four-five dilution increase in MICON MIC at all concentrations and one C. glabrata strain showed a fivefold MICON MIC increase when exposed to 4 MIC. Although an increase in MIC was noted in these two isolates, the MICON MIC was still very low (0.5 μg ml−1). In general, there was no increase in MIC demonstrated by repeated exposure to MICON in this study. “
“Mueller–Hinton modified agar (MH-GMB) was compared with RPMI + 2% glucose–agar to determine the MICs of 80 isolates of Cryptococcus neoformans and C. gattii to posaconazole with Etest. MH-GMB minimised trailing and agreement between both media was 94%. Agreement of M27-A2 microbroth reference method was 98% with RPMI and 94% with MB-GMB.

2b). Immunohistochemistry also shows that the sham-injured urethral sphincters are composed of distinct muscle tissues containing numerous myoglobin- (Fig. 2c) and SMA-positive cells (Fig. 2d). In contrast, the

7-day-old freeze-injured internal urethral orifices appear to be relaxed, creating a larger orifice (Fig. 2e). The injured urethral sphincters show reactive changes, including loss of muscle mass and relative disorganization of the remaining muscle tissues (Fig. 2e). Accompanying these changes is the loss of the majority of the striated and smooth muscle cells (Fig. 2f) and the absence of most myoglobin- (Fig. 2g) and SMA- positive cells (Fig. 2h). These findings of induced ISD-related urinary incontinence are similar to other models of urinary incontinence4,48–50 with respect to loss of striated and smooth muscle and reduced leak point

pressures. The VX-809 in vivo urinary sphincters of patients with post-surgical urinary incontinence are irreversibly damaged. However, this appears not to be the case in our model system. The cell-free injected control rabbits show a weak but natural Tamoxifen recovery of striated and smooth muscle cells that is accompanied by a slight increase in leak point pressure. These results are not entirely surprising. Rabbits may have inherently different regenerative powers than humans. Additionally, and of possibly greater importance, the rabbits are young and in good health, in contrast to patients with ISD-related urinary incontinence, who are typically elderly and not in

good general health. In our rabbit model, we intentionally avoided more severe and serious sphincter damage that would have produced irreversible incontinence because of the potential for urethral stricture or perforation, followed by death. Thus, our model is considered to be an Anidulafungin (LY303366) acute incontinence of relatively short duration. Ten days after harvesting the bone marrow cells and placing them in culture, and 7 days after freeze-injury operation, we divide the rabbits into cell implantation and cell-free injection control groups.3 For the cell implantation group, we implant the 0.5 × 106 autologous bone marrow-derived cells suspended in 100 µL culture medium. A total of 2.0 × 106 cells are injected through a 29-gauge syringe needle into the injured regions at the 3-, 6-, 9-, and 12-o’clock positions. For the cell-free injection control group, we similarly inject 100 µL of cell-free culture medium. The number and volume of the implantation cells are chosen to avoid further damaging the host tissues or the implanted cells due to shear stress. At each operation, the retention of small swellings containing the implanted cells or control media is visually confirmed. At 7 days after cell implantation, the leak point pressure of the cell-implantation group, 13.15 ± 2.
