Abstract
Regulatory T (Treg ) cell therapy is a promising approach for immune tolerance induction in autoimmunity conditions and cell/organ transplantations. Insufficient isolation yields and impurity during downstream processes and Treg instability after adoptive transfer in inflammatory conditions are major limitations to Treg therapy, and indicate the importance of seeking a valid, reliable method for de-novo generation of Tregs . In this research, we evaluated Treg -like cells obtained from different Treg differentiation protocols in terms of their yield, purity and activity. Differentiation was performed on naive CD4+ cells and a naive CD4+ /Treg co-culture by using three different protocols - ectopic expression of forkhead box protein P3 (E-FoxP3), soluble transforming growth factor β (S-TGF) and small molecules [N-acetyl puromycin and SR1555 (N-Ac/SR)]. The results showed that a high yield of a homogeneous population of Treg -like cells could be achieved by the N-Ac/SR method under a T helper type 17 (Th17)-polarizing condition, particularly interleukin (IL)-6 and TGF-β, when compared with the E-FoxP3 and S-TGF methods. Surprisingly, SR completely inhibited the differentiation of IL-17-producing cells and facilitated Treg generation in the inflammatory condition and had highly suppressive activity against T cell proliferation without Treg -specific demethylase region (TSDR) demethylation. For the first time, to our knowledge, we report the generation of efficient, pure Treg -like cells by using small molecules during in-vitro inflammatory conditions. Our results suggested that the N-Ac/SR method has several advantages for Treg generation when compared with the other methods, including a higher purity of Tregs , easier procedure, superior suppressive activity during the inflammatory condition and decreased cost.

Abstract
Objectives Embryonic stem cells (ESCs) are of significant interest as a renewable source of nonproliferating cells. Differentiation of ESCs is initiated by the formation of embryoid bodies (EBs). Standard methods of EB formation are limited in their production capacity, in any variations in EB size and formation of EBs through frequent passages. Here we have reported the utility of a microencapsulation technique for overcoming these limitations by mass production of mouse ESCs in alginate beads called ESC spheres. Methods The mouse ESCs were encapsulated in 1.2% alginate solution and cocultured on a feeder layer. The cells were evaluated by flow cytometry, in vitro differentiation, immunofluorescence, and reverse transcriptase polymerase chain reaction (RT-PCR). Results Analysis of encapsulated ESC spheres by flow cytometry showed similar percentages of Oct-4 and stage-specific embryonic antigen-1 (SSEA-1) expression in comparison with routine culture of ESCs. Moreover, the ESC spheres maintained a pluripotency potential which was comparable with ESCs cultured on feeder cells directly, as demonstrated by immunofluorescence and RT-PCR. Conclusions The results demonstrated that alginate encapsulation as a simple bioreactor, provides a scalable system for mass undifferentiated ESC sphere production with similar sizes and without the need for frequent passages for differentiation and clinical and pharmaceutical applications.

Abstract
Small molecules are being increasingly used for inducing the targeted differentiation of stem cells to different cell types. However, until now no systematic method for selecting suitable small molecules for this purpose has been presented. In this work, we propose an integrated and general bioinformatics- and cheminformatics-based approach for selecting small molecules which direct cellular differentiation in the desired way. The approach was successfully experimentally validated for differentiating stem cells into cardiomyocytes. All predicted compounds enhanced expression of cardiac progenitor (Gata4, Nkx2-5 and Mef2c) and mature cardiac markers (Actc1, myh6) significantly during and post-cardiac progenitor formation. The best-performing compound, Famotidine, increased the percentage of Myh6-positive cells from 33 to 56%, and enhanced the expression of Nkx2.5 and Tnnt2 cardiac progenitor and cardiac markers in protein level. The approach employed in the study is applicable to all other stem cell differentiation settings where gene expression data are available.

Abstract
Multiple sclerosis (MS) is a chronic, progressive demyelinating disorder which affects the central nervous system (CNS) and is recognized as the major cause of nervous system disability in young adults. Enhancing myelin repair by stimulating endogenous progenitors is a main goal in efforts for MS treatment. Fingolimod (FTY720) which is administrated as an oral medicine for relapsing-remitting MS has direct effects on neural cells. In this study, we hypothesized if daily treatment with FTY720 enhances endogenous myelin repair in a model of local demyelination induced by lysolecithin (LPC). We examined the response of inflammatory cells as well as resident OPCs and evaluated the number of newly produced myelinating cells in animals which were under daily treatment with FTY720. FTY720 at doses 0.3 and 1mg/kg decreased the inflammation score at the site of LPC injection and decreased the extent of demyelination. FTY720 especially at the lower dose increased the number of remyelinated axons and newly produced myelinating cells. These data indicate that repetitive treatment with FTY720, behind an anti-inflammatory effect, exerts beneficial effects on the process of endogenous repair of demyelinating insults.

Abstract
Fibronectin type III domain containing 5 (Fndc5) has already been distinguished to be involved in neural differentiation. However, cellular events of Fndc5 function are still ambiguous in the nervous system. One approach to shed light on duty of this protein in the nervous system is to find its cross-talks with various signaling pathways with defined characteristics and roles. Identification of the underlying molecular mechanism which controls Fndc5 expression and switches its activity up and down enables us to find out the Fndc5 functional map in the nervous system and other human body systems. Retinoic acid (RA) is a bio-small molecule which exerts its role as a neural inducer in the neurodevelopmental process of neural tube. RA up-regulates the expression of various genes involved in neural differentiation process via two distinct pathways: the genomic and the non-genomic. Our previous study has revealed that RA induces Fndc5 expression during neural differentiation process. In this study we have evaluated our hypothesis about the non-genomic up regulation of Fndc5 expression by RA. Interestingly we have identified that there is an association between ERK signaling pathway and Fndc5 expression. Furthermore, inhibition of this pathway by PD0325901 dramatically reduced Fndc5 mRNA level, while activating the pathway up-regulated Fndc5 transcription. In addition, it has been proven that ERK1/2 modulation via RA has more significant controlling effect on Fndc5 promoter rather than bFGF. This led us to conclude that RA enhances Fndc5 expression through a non-genomic pathway via the ERK signaling pathway.

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
Royan B(1) stem cell can be differentiated to specialized cell types including cardiomyocytes. This developmental change is accompanied with expression of various K(+) channel types. The aim of this study was to detect functional expression of K(+) currents from stem cell stage and one week and two weeks after differentiation into cardiomyocyte. Mouse stem cell derived cardiomyocytes (ES-cardiomyocytes) were isolated to single cell suspension for K(+) current recording using whole cell patch-clamp technique. The predominant depolarizing current in ES-cardiomyocytes was a tetraethylammonium (TEA) (10 mM) sensitive current which was partially blocked by nifedipine (1 μM) and attenuated by increasing concentration of EGTA (10 mM) in the pipette solution. Pharmacology and electrophysiological properties of this oscillatory sustained current very well matched with characteristics of Ca(2+) activated K(+) current. In addition there was another kind of sustained outward K(+) current which was resistance to TEA but was inhibited by 3,4-diaminopyridine. The characteristic features of this current indicate that this current was due to activation of delayed rectifier K(+) channels. RT-PCR study also confirmed expression of these two types of K(+) channels in ES-cardiomyocytes. Therefore, present study shows functional expression of two types of K(+) ionic current in ES-cardiomyocytes.

Abstract
Several types of cells including mature hepatocytes, adult liver progenitor cells and human embryonic stem cells, fetal liver progenitor cells, bone marrow derived hematopoietic or mesenchymal stem cells, and umbilical cord blood cells-both in rodents and humans-have been reported to be capable of self-replication, giving rise to daughter hepatocytes, both in vivo and in vitro. They have been shown to be able to repopulate liver in both animal models of liver injury and in patients with liver disease and to improve liver function. Human embryonic stem cell therapy seems to be a great promise for the treatment of liver cirrhosis, but there is no human clinical application due to ethical concerns or difficulties in harvesting or safely and efficiently expanding sufficient quantities. In contrast, adult bone marrow-derived hematopoietic or mesenchymal stem cells, which can be easily and safely harvested, have been used in clinical trials to treat several chronic diseases including chronic liver disease. Cell therapy offers exciting promise for future treatment of cirrhosis and metabolic liver diseases, but significant technical hurdles remain that will only be overcome through years of intensive research. There is also serious concern about the long-term safety of stem cell therapy and the possibility of tumor development. Herein, we present our experience with cell therapy in treatment of chronic liver disease in Iran.

Abstract
Embryonic stem cells are capable of differentiating to variety of cell tissues including cardiomyocytes. This developmental change is accompanied with a great deal of ion channel expression and functions. Mouse stem cell derived cardiomyocytes were prepared and separated to yield isolated single cell suspension for cell current recording. In the present study some properties of the K(+)-current in Royan B(1) stem cell derived cardiomyocytes were investigated using whole cell patch-clamp technique. When the holding potential was - 60 mV, in some cells a major outward current was elicited by square depolarizing pulses from -60 mV to +50 mV. This outward current was sustained for the duration of 300 ms test pulse. The sustained outward K(+) current was inhibited by tetraethylammonium (10 mM) indicating the activity of Ca(2+) activated K(+) channel in these cells. In some of the cells with 0.2 mM 3,ethylene glycol-bis (β-aminoethyl ether) N,N,N(`),N(`)-tetraacetic acid in the pipette, only a very small outward current was recorded which suggests that in these cells the voltage activated K(+) channels is either absent or if existed it is not fully functional. Other cells were in far between, indicating that voltage activated K(+) channels are developing in these cells but it is not yet fully functional. In conclusion, we have identified functional large conductance Ca(2+) activated K(+) channel in Royan B(1) stem cell derived cardiomyocytes.

Abstract
AbstractMagnetic iron oxide (maghemite, Fe3O4) particles were encapsulated with polyester resin. The resulting magnetic powders were characterized by Fourier transform infrared spectroscopy (FTIR), thermo gravimetric analysis (TGA), differential scanning calorimetry (DSC), Fritsch particle sizer, scanning electron microscopy (SEM), X-ray diffractometer (XRD) and vibrating sample magnetometer (VSM) measurements. FTIR and XRD confirmed the presence of iron oxide in polymer phase. The TGA and DSC measurements indicated the magnetic polymer particles have more than 50% iron oxide content and high thermal stability. SEM revealed that all maghemite particles were embedded in the polymer phase. The size distribution analysis of prepared magnetic particles has shown that the mean diameter of the bare iron oxide particles slightly increased with encapsulation. According to our magnetometry data, shape of the loops evidences the ferromagnetic character of the material and no evidence of superparamagnetism was seen.
