Abstract
The secondary heart field (SHF) progenitors ultimately contributes to diverse cardiovascular cell types through the formation of an early, multipotent heart progenitor pool and are marked by expression of ISL1, a LIM-homeodomain transcription factor. Human SHF can be derived from human pluripotent stem cells but their characterization has been limited due to the inefficiency of the differentiation protocols and lack of a proper reporter or surface marker based purification system. Using genetic tools and antibiotic selection we were able to purify ISL1+ cells for global gene expression analysis to identify key pathways that SHF identity. Genetic and small molecule based manipulation of these pathways alter ISL1 induction in differentiating cultures. Further proteomic analysis of enriched ISL1+ cells identified a hit surface marker that enables prospective isolation of ISL1+ secondary heart field progenitor cells with more than 90% purity. Purified SHF cells were multipotent and differentiate into pacemaker cells, endothelial and smooth muscle cells as well as mature beating cardiomyocytes. Finally transplantation of hPSC-derived purified SHF progenitors using this surface marker, restored myocardial function and regenerated infarcted area in mice myocardial infarction model.

Abstract
Despite its numerous limitations, liver transplants are the only definite cure for end-stage liver disease. Various stem cell populations may contribute to liver regeneration, of which there is accumulating evidence of the contribution of mesenchymal stem cells (MSCs). This study examines the hypothesis that repeated infusions of human bone marrow-derived MSCs (hBMMSCs)can improve liver injury in an experimental model. MSCs were intravenously transplanted into immunosuppressed mice with carbon tetrachloride (CCl(4))-induced liver fibrosis. Transplanting 3x10(6) MSCs in three divided doses improved survival,liver fibrosis and necrosis compared with injection of the same number of MSCs in a single dose. This was accompanied by increased influence on the expression of the fibrogenic/fibrolytic related genes Col1a1, Timp1 and Mmp13 in the repeated transplant group. Repeat administration of MSCs was three times more effective in homing of PKH-tagged transplanted cells 3 weeks post-transplant compared with the single transplant group. The benefits of repeated transplants may be of considerable significance in clinical trials on liver failure.

Abstract
Objective Pancreatic stroma plays an important role in the induction of pancreatic cells
by the use of close range signaling. In this respect, we presume that pancreatic mesenchymal cells (PMCs) as a fundamental factor of the stromal niche may have an effective
role in differentiation of umbilical cord blood cluster of differentiation 133+ (UCB-CD133+)
cells into newly-formed β-cells in vitro.
Materials and Methods This study is an experimental research. The UCB-CD133+cells
were purified by magnetic activated cell sorting (MACS) and differentiated into insulin
producing cells (IPCs) in co-culture, both directly and indirectly with rat PMCs. Immunocytochemistry and enzyme linked immune sorbent assay (ELISA) were used to determine
expression and production of insulin and C-peptide at the protein level.
Results Our results demonstrated that UCB-CD133+differentiated into IPCs. Cells in
islet-like clusters with (out) co-cultured with rat pancreatic stromal cells produced insulin
and C-peptide and released them into the culture medium at the end of the induction protocol. However they did not respond well to glucose challenges.
Conclusion Rat PMCs possibly affect differentiation of UCB-CD133+cells into IPCs by
increasing the number of immature β-cells.

Abstract
AIMS Regenerative therapies based on resident human cardiac progenitor cells (hCPCs) are a promising alternative to medical treatments for patients with myocardial infarction. However, hCPCs are rare in human heart and finding efficient source and proper surface marker for isolation of these cells would make them a good candidate for therapy. MAIN METHODS We have isolated 5.34∗10(6)±2.04∗10(5)/g viable cells from 35 heart tissue samples of 23 patients with congenital heart disease obtained during their heart surgery along with 6 samples from 3 normal subjects during cardiac biopsy. KEY FINDINGS According to FACS analysis, younger ages, atrial specimen and disease with increased pulmonary vascular resistance were associated with higher percentage of c-kit(+) (CD117) hCPCs. Analysis for other stemness markers revealed increased CD133(+) cells in the hearts of patients with congenital heart disease. By using both immune-labeling and PCR, we demonstrated that these cells express key cardiac lineage and endothelial transcription factors and structural proteins during in vitro differentiation and do express stemness transcription factors in undifferentiated state. Another novel datum of potentially relevant interest is their ability in promoting greater myocardial regeneration and better survival in rat model of myocardial infarction following transplantation. SIGNIFICANCE Our results could provide evidence for conditions associated with enriched hCPCs in patients with congenital heart disease. Moreover, we showed presence of a significant number of CD133 expressing cardiogenic stem-like cardiac precursors in the heart of patients with congenital heart disease, which could be isolated and stored for future regenerative therapies in these patients.

Abstract
Recent advances in the direct conversion of fibroblasts to cardiomyocytes suggest this process as a novel promising approach for cardiac cell-based therapies. Here, by screening the effects of 10 candidate small molecules along with transient overexpression of Yamanaka factors, we show ascorbic acid (AA), also known as vitamin C, enhances reprogramming of mouse fibroblasts into beating cardiomyocytes. Immunostaining and gene expression analyses for pluripotency and cardiac lineage markers confirmed beating patches were derived from non-cardiac lineage cells without passing through a pluripotent intermediate. Further analysis revealed that AA also increased the size of the beating areas and the number of cardiac progenitors. Immunostaining for cardiac markers, as well as electrophysiological analysis confirmed the functionality of directly converted cardiomyocytes. These results illustrate the importance of AA in direct conversion of fibroblasts to cardiomyocytes and may open new insights into future biomedical applications for induced cardiomyocytes.

Abstract
Embryonic stem cells offer multiple advantages over adult stem cells in terms of achieving acceptable number of functional cardiomyocytes to be exploited in cell therapy. However, differentiation efficacy is still a major issue to be solved before moving to regenerative medicine. Although a vast number of chemical compounds have been tested on efficiency of cardiac differentiation, the effect of fish oil components, such as eicosapentaenoic acid (EPA) on developmental bioenergetics, and hence cardiac differentiation, remained unstudied. EPA has been reported to have several cardioprotective effects, but there is no study addressing its role in cardiac differentiation. After mesoderm induction of embryoid bodies (EBs) derived from mouse embryonic stem cells (mESCs) in hanging drops initiated by ascorbic acid, they were treated with various concentrations of EPA. Gene and protein expression and functional properties of cardiomyocytes derived from ESCs were evaluated following treatment with various concentrations of EPA. Exposure to low concentrations of EPA (10 μM) increased percentage of beating colonies and beating area. This treatment also resulted in up to 3 fold increase in expression of NKX2-5, MEF2C, MYH6, TNNT2 and CX43. FACS analysis confirmed gene expression analysis with increased percentage of MYH6 positive cells in EPA-treated group compared to the control group. In contrast, the expression of genes coding for cardiac differentiation, remained constant or even declined with higher concentrations of EPA. In conclusion, we have demonstrated that treatment of mESCs undergoing cardiac differentiation with low concentration, but not high concentration of EPA up-regulate transcription of genes associated with cardiac development.

Abstract
Objective Hypertrophic scar involves excessive amounts of collagen in dermal layer and
may be painful. Nowadays, we can’t be sure about effectiveness of procedure for hypertrophic scar management. The application of stem cells with natural scaffold has been the
best option for treatment of burn wounds and skin defect, in recent decades. Fibrin glue
(FG) was among the first of the natural biomaterials applied to enhance skin deformity in
burn patients. This study aimed to identify an efficient, minimally invasive and economical
transplantation procedure using novel FG from human cord blood for treatment of hypertrophic scar and regulation collagen synthesis.
Materials and Methods In this case series study, eight patients were selected with hypertrophic scar due to full-thickness burns. Human keratinocytes and fibroblasts derived
from adult skin donors were isolated and cultured. They were tested for the expression of
cytokeratin 14 and vimentin using immunocytochemistry. FG was prepared from pooled
cord blood. Hypertrophic scars were extensively excised then grafted by simply placing
the sheet of FG containing autologous fibroblast and keratinocytes. Histological analyses
were performed using Hematoxylin and eosin (H&E) and Masson’s Trichrome (MT) staining of the biopsies after 8 weeks.
Results Cultured keratinocytes showed a high level of cytokeratin 14 expression and
also fibroblasts showed a high level of vimentin. Histological analyses of skin biopsies
after 8 weeks of transplantation revealed re-epithelialization with reduction of hypertrophic
scars in 2 patients.
Conclusion These results suggest may be the use of FG from cord blood, which is not
more efficient than previous biological transporters and increasing hypertrophic scar
relapse, but could lead to decrease pain rate.

Abstract
UNLABELLED Islet transplantation has been hampered by loss of function due to poor revascularization. We hypothesize that co-transplantation of islets with human embryonic stem cell-derived mesenchymal stromal cells that conditionally overexpress VEGF (hESC-MSC:VEGF) may augment islet revascularization and reduce the minimal islet mass required to reverse diabetes in mice. HESC-MSCs were transduced by recombinant lentiviruses that allowed conditional (Dox-regulated) overexpression of VEGF. HESC-MSC VEGF were characterized by tube formation assay. After co-transplantation of hESC-MSC:VEGF with murine islets in collagen-fibrin hydrogel in the omental pouch of diabetic nude mice, we measured blood glucose, body weight, glucose tolerance and serum C-peptide. As control, islets were transplanted alone or with non-transduced hESC-MSCs. Next, we compared functional parameters of 400 islets alone versus 200 islets co-transplanted with hESC-MSC:VEGF. As control, 200 islets were transplanted alone. Metabolic function of islets transplanted with hESC-MSC:VEGF significantly improved, accompanied by superior graft revascularization, compared with control groups. Transplantation of 200 islets with hESC-MSC:VEGF showed superior function over 400 islets alone. We conclude that co-transplantation of islets with VEGF-expressing hESC-MSCs allowed for at least a 50% reduction in minimal islet mass required to reverse diabetes in mice. This approach may contribute to alleviate the need for multiple donor organs per patient.

Abstract
Objective There is constant difficulty in obtaining adequate supplies of blood components, as well as disappointing performance of "universal" red blood cells. Advances in
somatic cell reprogramming of human-induced pluripotent stem cells (hiPSCs) have provided a valuable alternative source to differentiate into any desired cell type as a therapeutic promise to cure many human disease.
Materials and Methods In this experimental study, we examined the erythroid differentiation potential of normal Bombay hiPSCs (B-hiPSCs) and compared results
to human embryonic stem cell (hESC) lines. Because of lacking ABO blood group
expression in B-hiPSCs, it has been highlighted as a valuable source to produce any
cell type in vitro.
Results Similar to hESC lines, hemangioblasts derived from B-hiPSCs expressed approximately 9% KDR+CD31+ and approximately 5% CD31+CD34+. In semisolid media,
iPSC and hESC-derived hemangioblast formed mixed type of hematopoietic colony. In
mixed colonies, erythroid progenitors were capable to express CD71+GPA+HbF+ and accompanied by endothelial cells differentiation. Conclusion Finally, iPS and ES cells have been directly induced to erythropoiesis without hemangioblast formation that produced CD71+HbF+ erythroid cells. Although we observed
some variations in the efficiency of hematopoietic differentiation between iPSC and ES cells,
the pattern of differentiation was similar among all three tested lines.

Abstract
Objective As a biological tissue material, amniotic membrane (AM) has low immunogenicity and to date has been widely adopted in clinical practice. However, some features
such as low biomechanical consistency and rapid biodegradation is limited the application
of AM. Therefore, in this study, we fabricated a novel three-dimensional (3D) spongy scaffold made of the extracellular matrix (ECM) of denuded AM. Due to their unique characteristics which are similar to the skin, these scaffolds can be considered as an alternative
option in skin tissue engineering.
Materials and Methods In this experimental study, cellular components of human amniotic
membrane (HAM) were removed with 0.03% (w/v) sodium dodecyl sulphate (SDS). Quantitative analysis was performed to determine levels of Glycosaminoglycans (GAGs), collagen, and
deoxyribonucleic acid (DNA). To increase the low efficiency and purity of the ECM component,
especially collagen and GAG, we applied an acid solubilization procedure hydrochloridric acid
(HCl 0.1 M) with pepsin (1 mg/ml). In the present experiment 1-ethyl-3-(3-dimethyl aminopropyl) carbodiimide hydrochloride (EDC)/N-hydroxysuccinimide (NHS) cross linker agent was
used to improve the mechanical properties of 3D lyophilized AM scaffold. The spongy 3D AM
scaffolds were specified, by scanning electron microscopy, hematoxylin and eosin (H&E) staining, a swelling test, and mechanical strength and in vitro biodegradation tests. Human fetal
fibroblast culture systems were used to establish that the scaffolds were cytocompatible.
Results Histological analysis of treated human AM showed impressive removal of cellular components. DNA content was diminished after treatment (39 ± 4.06 μg/ml vs. 341 ±
29.60 μg/ml). Differences were observed between cellular and denude AM in matrix collagen (478 ± 18.06 μg/mg vs. 361 ± 27.47 μg/mg).With the optimum concentration of 1 mM
NHS/EDC ratio1:4, chemical cross-linker agent could significantly increase the mechanical property, and resistance to collagenase digestion. The results of 2, 4, 6-Trinitrobenzenesulfonic acid (TNBS) test showed that cross-linking efficiency of AM derived ECM scaffolds was about 65% ± 10.53. Scaffolds treated with NHS/EDC cross-linker agent by 100
μg/ml collagenase, lost 75% of their dry weight after 14 days. The average pore size of
3D spongy scaffold was 160 µm measured from scanning electron microscope (SEM) images that it is suitable for cell penetration, nutrients and gas change. In addition, the NHS/
EDC cross-linked AM scaffolds were able to support human fetal fibroblast cell proliferation in vitro. Extracts and contact prepared from the 3D spongy scaffold of AM showed a
significant increase in the attachment and proliferation of the human fetal fibroblasts cells. Conclusion The extra-cellular matrix of denuded AM-based scaffold displays the main
properties required for substitute skin including natural in vitro biodegradation, similar
physical and mechanical characterization, nontoxic biomaterial and no toxic effect on cell
attachment and cell proliferation.

Abstract
BACKGROUND Clinically, acute kidney injury (AKI) is a potentially devastating condition for which no specific therapy improves efficacy of the repair process. Bone marrow mesenchymal stromal cells (BM-MSCs) are proven to be beneficial for the renal repair process after AKI in different experimental rodent models, but their efficacy in large animals and humans remains unknown. This study aims to assess the effect of autologous rhesus Macaque mulatta monkey BM-MSC transplantation in cisplatin-induced AKI. METHODS We chose a model of AKI induced by intravenous administration of 5 mg/kg cisplatin. BM-MSCs were transplanted through intra-arterial injection. The animals were followed for survival, biochemistry analysis and pathology. RESULTS Transplantation of 5 × 10(6) cells/kg ameliorated renal function during the first week, as shown by significantly lower serum creatinine and urea values and higher urine creatinine and urea clearance without hyponatremia, hyperkalemia, proteinuria and polyuria up to 84 d compared with the vehicle and control groups. The superparamagnetic iron oxide nanoparticle-labeled cells were found in both the glomeruli and tubules. BM-MSCs markedly accelerated Foxp3+ T-regulatory cells in response to cisplatin-induced damage, as revealed by higher numbers of Foxp3+ cells within the tubuli of these monkeys compared with cisplatin-treated monkeys in the control and vehicle groups. CONCLUSIONS These data demonstrate that BM-MSCs in this unique large-animal model of cisplatin-induced AKI exhibited recovery and protective properties.

Abstract
OBJECTIVE In vitro production of a definitive endoderm (DE) is an important issue in stem cell-related differentiation studies and it can assist with the production of more efficient endoderm derivatives for therapeutic applications. Despite tremendous progress in DE differentiation of human embryonic stem cells (hESCs), researchers have yet to discover universal, efficient and cost-effective protocols. MATERIALS AND METHODS In this experimental study, we have treated hESCs with 200 nM of Stauprimide (Spd) for one day followed by activin A (50 ng/ml; A50) for the next three days (Spd-A50). In the positive control group, hESCs were treated with Wnt3a (25 ng/ml) and activin A (100 ng/ml) for the first day followed by activin A for the next three days (100 ng/ml; W/A100-A100). RESULTS Gene expression analysis showed up regulation of DE-specific marker genes (SOX17, FOXA2 and CXCR4) comparable to that observed in the positive control group. Expression of the other lineage specific markers did not significantly change (p<0.05). We also obtained the same gene expression results using another hESC line. The use of higher concentrations of Spd (400 and 800 nM) in the Spd-A50 protocol caused an increase in the expression SOX17 as well as a dramatic increase in mortality rate of the hESCs. A lower concentration of activin A (25 ng/ml) was not able to up regulate the DE-specific marker genes. Then, A50 was replaced by inducers of definitive endoderm; IDE1/2 (IDE1 and IDE2), two previously reported small molecule (SM) inducers of DE, in our protocol (Spd-IDE1/2). This replacement resulted in the up regulation of visceral endoderm (VE) marker (SOX7) but not DE-specific markers. Therefore, while the Spd-A50 protocol led to DE production, we have shown that IDE1/2 could not fully replace activin A in DE induction of hESCs. CONCLUSION These findings can assist with the design of more efficient chemically-defined protocols for DE induction of hESCs and lead to a better understanding of the different signaling networks that are involved in DE differentiation of hESCs.

Abstract
Recent advances in human embryonic and induced pluripotent stem cell-based therapies in animal models of hepatic failure have led to an increased appreciation of the need to translate the proof-of-principle concepts into more practical and feasible protocols for scale up and manufacturing of functional hepatocytes. In this study, we describe a scalable stirred-suspension bioreactor culture of functional hepatocyte-like cells (HLCs) from the human pluripotent stem cells (hPSCs). To promote the initial differentiation of hPSCs in a carrier-free suspension stirred bioreactor into definitive endoderm, we used rapamycin for "priming" phase and activin A for induction. The cells were further differentiated into HLCs in the same system. HLCs were characterized and then purified based on their physiological function, the uptake of DiI-acetylated low-density lipoprotein (LDL) by flow cytometry without genetic manipulation or antibody labeling. The sorted cells were transplanted into the spleens of mice with acute liver injury from carbon tetrachloride. The differentiated HLCs had multiple features of primary hepatocytes, for example, the expression patterns of liver-specific marker genes, albumin secretion, urea production, collagen synthesis, indocyanin green and LDL uptake, glycogen storage, and inducible cytochrome P450 activity. They increased the survival rate, engrafted successfully into the liver, and continued to present hepatic function (i.e., albumin secretion after implantation). This amenable scaling up and outlined enrichment strategy provides a new platform for generating functional HLCs. This integrated approach may facilitate biomedical applications of the hPSC-derived hepatocytes.

Abstract
The generation of human induced pluripotent stem cells (hiPSCs) from an individual patient provides a unique tool for disease modeling, drug discovery, and cell replacement therapies. Patient-specific pluripotent stem cells can be expanded in vitro and are thus suitable for genetic manipulations. To date, several genetic liver disorders have been modeled using patient-specific hiPSCs. Here, we present the generation of corrected hepatocyte-like cells (HLCs) from hiPSCs of a familial hypercholesterolemia (FH) patient with a homozygous mutation in the low-density lipoprotein receptor (LDLR) gene. We generated hiPSCs from a patient with FH with the mutated gene encoding a truncated non-functional receptor. In order to deliver normal LDLR to the defective cells, we used a plasmid vector carrying the normal receptor ORF to genetically transform the hiPSCs. The transformed cells were expanded and directed toward HLCs. Undifferentiated defective hiPSCs and HLCs differentiated from the defective hiPSCs did not have the ability to uptake labeled low-density lipoprotein (LDL) particles. The differentiated transformed hiPSCs showed LDL-uptake ability and the correction of disease phenotype as well as expressions of hepatocyte-specific markers. The functionality of differentiated cells was also confirmed by indo-cyanine green (ICG) uptake assay, PAS staining, inducible cyp450 activity, and oil red staining. These data suggest that hiPSC technology can be used for generation of disease-corrected, patient-specific HLCs with potential value for disease modeling and drug discovery as well as cell therapy applications in future.

Abstract
Despite the enormous progress in studying definitive endoderm (DE) differentiation from human embryonic stem cells (hESCs), none of the reported protocols have produced a universal, cost-effective, and competent DE with the capability to further differentiate into endodermal derivatives. In this study, by using a 2-step differentiation strategy, we have treated hESCs for 1 day with "priming" small molecules (SM), [stauprimide, NSC-308848, rapamycin (Rapa), and/or CHIR] and for the next 3 days with "inducing" SM (LY294002, cymarin, IDE1, and/or IDE2) in conjunction with activin A. In the positive control group, we treated hESCs with Wnt3a (25 ng/mL) for 1 day and activin A (100 ng/mL; W/A100-A100) for the next 3 days. Gene expression analysis showed that treatment of hESCs with 100 nM Rapa and 50 ng/mL activin A (Rapa-A50) out of 25 combinations of factors gave rise to higher expressions of 2 DE-specific genes, SOX17 and FOXA2. Similar results were obtained after treating 2 other hESC lines with this regimen. To investigate the competency of Rapa-A50-induced DE for further differentiation into endodermal derivatives, these cells and W/A100-A100-induced DE cells (positive control) were further differentiated into pancreatic progenitors (PP), then into pancreatic endocrine (PE) cells using 5 previously described differentiation protocols. Gene analysis of differentiated cells showed that the established protocols were insufficient to enable universal differentiation into PE, whereas Rapa-A50-induced DE cells were more competent for PP differentiation in a protocol-dependent manner. Additionally, Rapa-A50-induced DE had the capability to differentiate into hepatocyte-like cells (HLCs) as efficiently as W/A100-A100-induced DE. These data have indicated that hESCs primed with Rapa, and induced by a lower concentration of activin A, could lead to DE that had the capability to further differentiate into HLCs and PP cells, but not PE cells. Thus, current protocols for the differentiation of DE into PE still need additional study.

Abstract
BACKGROUND Human embryonic stem cells (hESCs) have the potential to provide an unlimited source of cardiomyocytes, which are invaluable resources for drug or toxicology screening, medical research, and cell therapy. Currently a number of obstacles exist such as the insufficient efficiency of differentiation protocols, which should be overcome before hESC-derived cardiomyocytes can be used for clinical applications. Although the differentiation efficiency can be improved by the genetic manipulation of hESCs to over-express cardiac-specific transcription factors, these differentiated cells are not safe enough to be applied in cell therapy. Protein transduction has been demonstrated as an alternative approach for increasing the efficiency of hESCs differentiation toward cardiomyocytes. METHODS We present an efficient protocol for the differentiation of hESCs in suspension by direct introduction of a LIM homeodomain transcription factor, Islet1 (ISL1) recombinant protein into the cells. RESULTS We found that the highest beating clusters were derived by continuous treatment of hESCs with 40 µg/ml recombinant ISL1 protein during days 1-8 after the initiation of differentiation. The treatment resulted in up to a 3-fold increase in the number of beating areas. In addition, the number of cells that expressed cardiac specific markers (cTnT, CONNEXIN 43, ACTININ, and GATA4) doubled. This protocol was also reproducible for another hESC line. CONCLUSIONS This study has presented a new, efficient, and reproducible procedure for cardiomyocytes differentiation. Our results will pave the way for scaled up and controlled differentiation of hESCs to be used for biomedical applications in a bioreactor culture system.

Abstract
Bone marrow-derived mesenchymal stem cells (MSCs) have the capacity to regenerate renal tubule epithelia and repair renal function without fusing with resident tubular cells. The goal of the present project was to investigate the role of MSCs secreted cytokines on tubule cell viability and regeneration after a toxic insult, using a conditionally immortalized human proximal tubule epithelial cell (ciPTEC) line. Gentamicin was used to induce nephrotoxicity, and cell viability and migration were studied in absence and presence of human MSC-conditioned medium (hMSC-CM) i.e. medium containing soluble factors produced and secreted by MSCs. Exposure of ciPTEC to 0-3000 μg/ml gentamicin for 24 h caused a significant dose-dependent increase in cell death. We further demonstrated that the nephrotoxic effect of 2000 μg/ml gentamicin was recovered partially by exposing cells to hMSC-CM. Moreover, exposure of ciPTEC to gentamicin (1500-3000 μg/ml) for 7 days completely attenuated the migratory capacity of the cells. In addition, following scrape-wounding, cell migration of both untreated and gentamicin-exposed cells was increased in the presence of hMSC-CM, as compared to exposures to normal medium, indicating improved cell recovery. Our data suggest that cytokines secreted by MSCs stimulate renal tubule cell regeneration after nephrotoxicity.

Abstract
BACKGROUND The implantation of a CD133+ bone marrow cell population into an ischemic myocardium has emerged as a promising therapeutic modality for myocardial regeneration and restoration of ventricular contractility. While previous studies have documented the short-term safety and efficacy of CD133+ cell transplantation in patients with acute myocardial infarction, there are few reports of long-term follow-up results. Here, we present the results of long-term follow-up of our acute myocardial infarction patients who were treated with intramyocardial injection of CD133+ cells after coronary bypass graft. METHODS After five years, 13 patients in the cell transplantation group and 5 patients in the control group underwent safety and efficacy investigations by New York Heart Association classification and two-dimensional echocardiography (2D echo). RESULTS During the five-year study period, no major cardiac adverse events were reported among patients who received CD133+ stem cells. Regarding efficiency, we observed no statistically significant treatment effects for the echocardiographic parameters [left ventricular end-diastolic and end-systolic volumes, and resting ejection fraction] measured during the follow-up period. However, detailed analysis of regional wall motion revealed an improvement in the Wall Motion Score Index from baseline to the six month follow-up, which was maintained during the follow-up period. CONCLUSION Taken together, the long-term results of the present study indicate that transplantation of CD133+ is a safe and feasible procedure; however, we could not show any major benefits in our patients. Thus, this issue needs to be addressed by conducting other studies with more patients.

Abstract
We describe a new, efficient protocol that involves the serial addition of noggin, basic fibroblast growth factor (bFGF), retinoic acid, and sonic hedgehog (Shh) for the differentiation of human induced pluripotent stem cells (hiPSC) to retinal pigmented epithelium (RPE) in a serum- and feeder-free adherent condition. hiPSC-RPE cells exhibited RPE morphology and specific molecular markers. Additionally, several hiPSC lines were generated from retinal-specific patients with Leber's congenital amaurosis, Usher syndrome, two patients with retinitis pigmentosa, and a patient with Leber's hereditary optic neuropathy. The RPE cells generated from these disease-specific hiPSCs expressed specific markers by the same RPE lineage-directed differentiation protocol. These findings indicate a new short-term, simple, and efficient protocol for differentiation of hiPSCs to RPE cells. Such specific retinal disease-specific hiPSCs offer an unprecedented opportunity to recapitulate normal and pathologic formation of human retinal cells in vitro, thereby enabling pharmaceutical screening, and potentially autologous cell replacement therapies for retinal diseases.

Abstract
OBJECTIVE The aim of this study was to test the effect of intravenous injection of mesenchymal stem cells (MSCs) on doxorubicin (DOX)-induced fibrosis in the heart. We investigated the mechanisms that possibly mediate this effect. MATERIALS AND METHODS In this experimental study, fibrosis in the myocardium of adult male Wistar rats (weights 180-200 g, 9-10 weeks of age, total n=30) was created by DOX administration. DOX (2.5 mg/kg) was administered intraperitoneally 3 times a week, for a total dose of 15 mg/kg over a period of 2 weeks. MSCs from Wistar rats were separated and cultured in Dulbecco's modified eagle medium (DMEM). The condition medium (CM) which contained factors secreted by MSCs was also collected from MSCs cultured in serum-free DMEM. Two weeks after the first injection of DOX, MSCs, CM and standard medium (SM) were transplanted via intravenous injection. Four weeks after transplantation, histological (Masson's trichrome staining for fibrosis detection) and molecular [real-time polymerase chain reaction (RT-PCR)] analyses were conducted. In addition, insulin-like growth factor (IGF-1) and hepatocyte growth factor (HGF) in the CM were measured with an enzyme-linked immunosorbent assay (ELISA). For immunosuppressive treatment, cyclosporine A was given (intraperitoneally, 5 mg/kg/day) starting on the day of surgery until the end of study in all groups. Fibrosis rate and relative gene expression were compared by analysis of variance (ANOVA) and post-Tukey's test. HGF and (IGF-1 in the CM were analyzed by independent sample t test. P<0.01 was considered statistically significant. RESULTS Our data demonstrated that intravenously transplanted MSCs and CM significantly reduced fibrosis and significantly increased Bcl-2 expression levels in the myocardium compared to the DOX group (p<0.01). However, there was no significant difference between Bax expression levels in these groups. In addition, secretion of HGF and IGF-1 was detected in the CM (p<0.01). CONCLUSION We conclude that intravenous transplantation of MSCs and CM can attenuate myocardial fibrosis and increase Bcl-2 expression. This may be mediated by paracrine signaling from MSCs via anti-fibrotic and anti-apoptotic factors such as HGF and IGF-1.

Abstract
BACKGROUND Despite the suitability of a mouse model for preclinical investigations; little is known regarding mesenchymal stem cells derived from murine amniotic fluid. This is the subject of the present study. METHODS Amniotic fluid was collected from NMRI mice during the second weeks of pregnancy and plated. The cells that adhered to the culture surfaces were propagated with three successive subcultures and then characterized. To determine the differentiation potential, the cells were cultivated under osteogenic, adipogenic, and chondrogenic conditions, and followed by specific staining and RT-PCR analysis for differentiation. The proliferative potential of the cells were measured with clonogenic assays, population doubling time and number and by growth curve plotting. Cellular aging was investigated with the senescence-associated ß-galactosidase staining method. RESULTS The amniotic fluid primary cell culture was composed of round flattened and fibroblastic cells. The latter dominated the culture after several passages. Successful tripotent differentiation of the isolated cells into bone, cartilage and adipose cells were indicative of their mesenchymal stem cells nature. The isolated cells appeared to be relatively proliferative cells as confirmed by the population doubling time value which was equal to about 69 hours. Furthermore, the cells were relatively clonogenic and they tended to initiate proliferation immediately after plating (there was no lag phase in their growth curve). ß-galactosidase positive cells were first observed at passage 3 and increased in number with subsequent passages. CONCLUSIONS Collectively it was concluded that murine amniotic fluid contained mesenchymal stem cells with relatively high proliferation property and typical tripotent differentiation potential.

Abstract
BACKGROUND Cirrhosis, the end stage of progressive hepatic fibrosis, is characterized by distortion of the hepatic architecture and the formation of regenerative nodules. Liver transplantation is one of the few available therapies for such patients. However, due to a severe shortage of organ donors, surgical complications, transplant rejection and the high cost of this procedure much interest has focused on research to find new treatment modalities for this disease. There is accumulating evidence for the contribution of bone marrow stem cells to participate in liver regeneration. METHODS Here we report on six patients with end stage liver disease who were subjected to intraportal administration of autologous bone marrow-derived CD133(+) in comparison to mononuclear cells in short-term (6 months) and long-term (24 months) follow up. RESULTS There were no adverse effects in any of the patients during the short- and long-term follow up period. Moreover, there were no significant alterations of liver function parameters, liver enzymes, serum albumin, creatinine, serum bilirubin and/or liver volume after transplantation of both types of autologous cells in these patients. CONCLUSION Our study has shown both the safety and feasibility of this type of liver cell therapy and may be a bridge to liver transplantation. The trial was registered with NIH clinical trials (www.clinicaltrials.gov) as identifier: NCT00713934.

Abstract
BACKGROUND Early clinical studies have suggested that administration of granulocyte-colony stimulating factor (G-CSF) may improve the clinical condition of patients suffering from myocardial infarction (MI).This prospective, randomized, double-blind, placebo-controlled single-centre trial aims to assess the safety and clinical efficacy of G-CSF administration in patients with subacute MI and impaired LV function undergoing delayed primary percutaneous coronary intervention (PCI). METHODS A total of 16 patients (13 men, mean age 51 years) with subacute ST-segment elevation MI and a left ventricular (LV) ejection fraction (EF) of less than 45% at baseline who underwent late revascularization, were included in the study. Patients were randomized in a double-blind fashion to receive either G-CSF (at a dose of 10 microg/kg body weight) or placebo for five consecutive days. End points consisted of assessment of safety parameters as well as changes of global and regional myocardial function from baseline until six months following PCI. RESULTS G-CSF administration resulted in a significant mobilization of different cell populations (four-fold increase in WBC count and a six-fold increase in CD34+ cells). G-CSF treatment was well tolerated in most patients and no major adverse cardiac events or severe G-CSF-related side effects were identified during hospitalization and at follow-up. No significant differences were observed between the G-CSF and placebo groups regarding global and regional myocardial function parameters. CONCLUSION G-CSF administration is safe, but not effective, in improving impaired LV functional parameters in patients with subacute MI who had an impaired baseline EF of less than 45%.

Abstract
The availability of disease-specific induced pluripotent stem cells (iPSCs) offers a unique opportunity for studying and modeling the effects of specific gene defects on human liver development in vitro and for testing small molecules or other potential therapies for relevant liver disorders. Here we report, for the first time, the derivation of iPSCs by the retroviral transduction of Yamanaka's factors in serum and feeder-free culture conditions from liver-specific patients with tyrosinemia, glycogen storage disease, progressive familial hereditary cholestasis, and two siblings with Crigler-Najjar syndrome. Furthermore, they were differentiated into functional hepatocyte-like cells efficiently. These iPSCs possessed properties of human embryonic stem cells (hESCs) and were successfully differentiated into three lineages that resembled hESC morphology, passaging, surface and pluripotency markers, normal karyotype, DNA methylation, and differentiation. The hepatic lineage-directed differentiation showed that the iPSC-derived hepatic cells expressed hepatocyte-specific markers. Their functionality was confirmed by glycogen and lipid storage activity, secretion of albumin, alpha-fetoprotein, and urea, CYP450 metabolic activity, as well as LDL and indocyanin green uptake. Our results provide proof of principal that human liver-disease specific iPSCs present an exciting potential venue toward cell-based therapeutics, drug metabolism, human liver development and disease models for liver failure disorders.

Abstract
Human embryonic stem cell (hESC)-derived hepatocytes provide a promising unlimited resource for the treatment of liver disease. However, current protocols for the generation of mature and functional hepatocytes are inefficient. Therefore, in order to better differentiate and maintain the function of differentiating hESCs, we have hypothesized that hESCs undergo better differentiation into hepatocyte-like cells (HLCs) when induced on three-dimensional nanofibrillar surfaces. We have demonstrated that, during stepwise differentiation of induction, the markers of hepatic lineage expressed and finally lead to the generation of functional mature cells. In the presence of an ultraweb nanofiber, HLCs produced lower AFP, greater urea, glycogen storage, metabolic PROD activity, uptake of LDL and organic anion ICG, all of which are indicative of the differentiation of HLCs. These results show that topographically treated hESCs at the nano level have a distinct hepatic functionality profile which has implications for cell therapies.

Abstract
Although human induced pluripotent stem cells (hiPSCs) hold great promise as a source of differentiated cells for vast therapeutic implications, many obstacles still need to be surmounted before this can become a reality. One obstacle, a robust feeder- and serum-free system to generate and expand hiPSCs in culture is still unavailable. Here, for the first time, we describe a novel establishment and maintenance culture technique that uses human dermal fibroblasts to generate hiPSCs by introducing four factors, Klf4, Oct4, Sox2, and c-Myc under serum- and feeder-independent conditions. We have used a serum replacement product, conditioned medium (CM), or feeder-free medium (FFM) supplemented with high elevated basic-fibroblast growth factor in the absence or presence of Matrigel. Our FFM system in the presence of Matrigel enhanced the efficiency of alkaline phosphatase-positive colonies at a frequency at least 10-fold greater than the conventional method on feeder cells. The established hiPSCs are similar to human embryonic stem cells in many aspects including morphology, passaging, surface and pluripotency markers, normal karyotype, gene expression, ultrastructure, and in vitro differentiation. Such hiPSCs could be useful particularly in the context of in vitro disease modeling, pharmaceutical screening and in cellular replacement therapies once the safety issues have been overcome.

Abstract
This study was initiated to evaluate the safety and effectiveness of intraepidermal injection of dissociated epidermal cells into the lesions of stable vitiligo patients. Autologous dissociated epidermal cell suspensions were injected intraepidermally into 10 stable vitiligo patients. None of the patients received adjuvant therapy. The response was evaluated as: marked (76-100%), moderate (51-75%), mild (26-50%) and minimal repigmentation (0-25%). Transmission electron microscopy was used to evaluate the transplanted cells and immunohistochemical staining with HMB-45 was performed to assess the repigmentation in vivo. In all cases, repigmentation started during the 4-week period after transplantation. Six months after transplantation, a marked repigmentation in four (40%), moderate repigmentation in two (20%) and mild repigmentation in two (20%) patients were observed. Two (20%) patients with white patches on their lids showed minimal repigmentation. No side effects were observed in any patients. Interestingly, repigmentation of gray hair in one patient, 4 months post transplantation was observed. Analysis of the ultrastructure of transplanted cells showed 1.5% of the cells had melanocyte morphology. HMB-45 positive cells were observed after cell transplantation. This method is an effective, simple and safe therapeutic option for stable vitiligo lesions.

Abstract
Progress in understanding the cellular and molecular biology of the immune system, in the second half of the 20(th) century brings the transplantation of replacement organs and tissues in clinical reality to cure disease. Immunosuppressive agents that are part of nearly every transplantation procedure, are toxic to some extent and their chronic use predisposes the patient to the development of infection and cancer. Alternatives to immunosuppression include modulation of host immune system to reduce the immune response and the induction of a state of immunologic tolerance. Induction of hematopoietic mixed chimerism through donor bone marrow transplantation offers a promising approach for tolerance induction as a prelude to organ transplantation. Furthermore, mesenchymal stromal cells have important effects on the host immune system and possess immune modulation properties that make them attractive for potential use in organ transplantation as immunosuppressant. Both modalities might potentially provide novel therapeutic options for treatment/prevention of rejection and/or repair of organ allografts through their multifaceted properties. In this review, evidences for the tolerogenic properties and mechanisms of hematopoietic mixed chimerism as well as mesenchymal stromal cells effects on allograft surveillance are summarized.

Abstract
Bombay phenotype is one of the rare phenotypes in the ABO blood group system that fails to express ABH antigens on red blood cells. Nonsense or missense mutations in fucosyltransfrase1 (FUT1) and fucosyltransfrase2 (FUT2) genes are known to create this phenotype. This blood group is compatible with all other blood groups as a donor, as it does not express the H antigen on the red blood cells. In this study, we describe the establishment of human induced pluripotent stem cells (iPSCs) from the dermal fibroblasts of a Bombay blood-type individual by the ectopic expression of established transcription factors Klf4, Oct4, Sox2, and c-Myc. Sequence analyses of fibroblasts and iPSCs revealed a nonsense mutation 826C to T (276 Gln to Ter) in the FUT1 gene and a missense mutation 739G to A (247 Gly to Ser) in the FUT2 gene in the Bombay phenotype under study. The established iPSCs resemble human embryonic stem cells in morphology, passaging, surface and pluripotency markers, normal karyotype, gene expression, DNA methylation of critical pluripotency genes, and in-vitro differentiation. The directed differentiation of the iPSCs into hematopoietic lineage cells displayed increased expression of the hematopoietic lineage markers such as CD34, CD133, RUNX1, KDR, alpha-globulin, and gamma-globulin. Such specific stem cells provide an unprecedented opportunity to produce a universal blood group donor, in-vitro, thus enabling cellular replacement therapies, once the safety issue is resolved.

Abstract
Dendritic cells (DCs) are the most potent antigen-presenting cells (APC) of the immune system, and are critically involved in initiation of immune responses in autoimmune diseases. They can modulate the nature of immune responses to stimulatory or tolerogenic fashion. Previous studies have demonstrated that the administration route of DCs is an important variable in eliciting anti-tumor immunity. In this study we used experimental autoimmune encephalomyelitis (EAE) as an animal model of multiple sclerosis to compare different protocols of DC delivery in autoimmunity or tolerance induction. Dendritic cells were generated from bone marrow cells of C57BL/6 mice by culturing in the presence of GM-CSF and IL-4 for 7 days, followed by 2 days culture with TNF-alpha. The obtained DCs were pulsed in vitro with myelin oligodendrocyte glycoprotein (MOG) peptide and injected (5 x 10(5) cells/mouse) via the intravenous (i.v.), intraperitoneal (i.p.) or subcutaneous (s.c.) route into female C57BL/6 mice. In some instances pertussis toxin was also injected zero and 48 hours after DC injection. After follow up of the mice pretreated in this way for 4 weeks, in the i.v. group in which no clinical signs of EAE occurred, the mice were immunized with MOG peptide for EAE induction via the common method and the results were compared with mice that were not pre-immunized. Only after three s.c. DC injections with pertussis toxin, the mice showed mild clinical signs of EAE, whereas mice given i.v. or i.p. injections with or without pertussis toxin failed to develop EAE after 4 weeks. Induction of EAE via the common method after three injections of TNF-alpha treated DCs, in i.v. injected groups showed no protection from EAE. It seems that several factors influence the tolerance versus immunity induction by DCs. Our results showed that the administration route of DCs is one of the pivotal factors in DC-based induction of autoimmune diseases.

Abstract
INTRODUCTION Arsenic trioxide is effective and approved for treatment of relapsed or refractory acute promyelocytic leukemia (APL) cases resistant to all-trans retinoic acid (ATRA), but its effect on new cases of APL is not clear. MATERIALS AND METHODS We studied 111 patients with APL. Arsenic trioxide was infused at 0.15 mg/kg daily dose, until complete remission was achieved. Then, after 28 days of rest, arsenic trioxide was infused daily for 28 days as consolidation therapy. We studied minimal residual disease (MRD) by semi-sensitive reverse transcription polymerase chain reaction (RT-PCR) on peripheral blood samples. RESULTS Complete remission was observed in 95 patients (85.6%). With the median (range) follow-up period of 16.5 (1-57) months, 1- and 2-year disease-free survival was 88.3% and 63.7%, respectively; 24 patients relapsed, 19 of whom achieved a second complete remission, again by arsenic trioxide. Third and fourth remissions were seen in some relapsed patients, again by arsenic trioxide. For patients in complete remission, 1- and 3-year survival was 95.5% and 87.6%, respectively. MRD was positive in four (8.3%) out of 48 cases during 1 year after remission induction; three of them relapsed clinically. CONCLUSIONS Arsenic trioxide is effective as first-line treatment for APL. Results of arsenic trioxide combination therapy with chemotherapy/ATRA requires further study.

Abstract
We carried out a case-control study is to investigate the relationship between iodine deficiency and stomach cancer. We compared the ratio of urinary iodine to urinary creatinine in 100 patients diagnosed with stomach cancer and 84 people in a control group. Mean urinary iodine levels were lower in the patients with stomach cancer, 61.9 microg/g creatinine, compared to 101.7 microg/g creatinine in the control group (P < 0.0001). More of the cancer patients (49.0%) had severe iodine deficiency (< 25 microg/g creatinine) than people in the control group (19.1%) (P< 0.0001). We found the relationship between stomach cancer and iodine deficiency to be significant.
