Abstract
Background L-carnitine (Lc) as a type of flavonoid antioxidants and bone marrow stromal cells (BMSCs) as a type of mesenchymal stem cells may recover damaged ovaries. It seems that Lc has favorable effects on differentiation, increasing lifespan and decreasing apoptosis in BMSCs. The aim of this study was to investigate effects of co-administration of BMSC+Lc on damaged ovaries after creating a chemotherapy model with cyclophosphamide in rats. Materials and Methods In this experimental study, cyclophosphamide was intraperitoneally (IP) injected to forty female wistar rats for 14 days, in terms of chemotherapy-induced ovarian destruction. The rats were then randomly divided into four groups: control, Lc, BMSCs and co-administration of BMSC+Lc. Injection of BMSCs into bilateral ovaries and intraperitoneal injection of Lc were performed individually and together. Four weeks later, levels of serum estradiol (E2) and follicle-stimulating hormone (FSH) using enzyme-linked immunosorbent assay (ELISA) kit, number of ovarian follicles at different stages using hematoxylin and eosin (H and E) staining and expression of ovarian Bcl-2 and Bax proteins using western blot were assessed. Results Co-administration of BMSC+Lc increased E2 and decreased FSH levels compared to the control group (P<0.001). The number of follicles was higher in the co-administrated group compared to the control group (P<0.001). Co-administration of BMSC+Lc increased Bcl-2 protein level, decreased Bax protein level and increased Bcl-2/Bax ratio (P<0.001). Conclusion The effect of co-administration of BMSC+Lc is probably more effective than the effect of their separate administration on the recovery of damaged ovaries by chemotherapy.

Abstract
OBJECTIVES Ghrelin is a peptide which has a proliferative and antiapoptotic effect in many cells including bone marrow stromal cells (BMSCs). Homeobox protein B4 (HOXB4) is a transcription factor involved in stem cell regeneration and survival. The aim of the study was to find out the efect of ghrelin on Hoxb4 expression in BMSCs. MATERIALS AND METHODS In this experimental study, rat BMSCs were cultivated in Dulbecco's Modified Eagle Medium (DMEM). Passage three BMSCs were treated with ghrelin 100 μM for 48 hours. Real-time polymerase chain reaction (PCR) was carried out from the untreated BMSCs (B), BMSCs treated with 125 μM H2O2 (BH), BMSCs treated with 100 μM ghrelin then 125 μM H2O2 (BGH) and BMSCs treated with 100 μM ghrelin (BG) groups. For immunofluorescence, cells were incubated with an anti-HOXB4 monoclonal antibody. Primary antibodies were visualized using the Fluorescein isothiocyanate (FITC) method. All data are presented as mean ± SEM and P<0.05 was considered as statistical significant. RESULTS Hoxb4 expression significantly increased in the BG compared with BH and BGH groups. Furthermore, 100 μM ghrelin, increased the mean of HOXB4 positive immunoreactive cells compared to the BH group. CONCLUSIONS Ghrelin probably enhances proliferation and viability of BMSCs through Hoxb4 upregulation. However, the signaling pathway and other biological outcomes of this effect should be elucidated in different stem cells.

Abstract
Objective Although stem cell transplantation has beneficial effects on tissue regeneration, but there are still problems
such as high cost and safety issues. Since stem cell therapy is largely dependent on paracrine activity, in this study,
utilization of transplantation of bone marrow stromal cells (BMSCs)-secretome instead of the cells, into damaged
ovaries was evaluated to overcome the limitations of stem cell transplantation.
Materials and Methods In this experimental study, BMSCs were cultured and 25-fold concentrated conditioned
medium (CM) from BMSCs was prepared. Female rats were injected intraperitoneally with cyclophosphamide (CTX)
for 14 days. Then, BMSCs and CM were individually transplanted into bilateral ovaries, and the ovaries were excised
after four weeks of treatment. The follicle count was performed using hematoxylin and eosin (H&E) staining and the
apoptotic cells were counted using TUNEL assay. Ovarian function was evaluated by monitoring the ability of ovulation
and the levels of serum estradiol (E2) and follicle-stimulating hormone (FSH).
Results Evaluation of the ovarian function and structure showed that results of secretome transplantation were almost
similar to those of BMSCs transplantation and there was no significant differences between them.
Conclusion BMSCs-secretome is likely responsible for the therapeutic paracrine effect of BMSCs. Stem cell-
secretome is expected to overcome the limitations of stem cell transplantation and become the basis of a novel therapy
for ovarian damage.

Abstract
Objective Bone marrow and umbilical cord stromal cells are multipotential stem cells
that have the ability to produce growth factors that play an important role in survival and
generation of axons. The goal of this study was to evaluate the effects of the two different
mesenchymal stem cells on peripheral nerve regeneration.
Materials and Methods In this experimental study, a 10 mm segment of the left sciatic
nerve of male Wistar rats (250-300 g) was removed with a silicone tube interposed into
this nerve gap. Bone marrow stromal cells (BMSCs) and human umbilical cord stromal
cells (HUCSCs) were respectively obtained from rat and human. The cells were sepa-
rately cultured and transplanted into the nerve gap. The sciatic nerve regeneration was
evaluated by immunohistochemistry, and light and electron microscopy. Moreover, histo-
morphology of the gastrocnemius muscle was observed.
Results The nerve regeneration in the BMSCs and HUCSCs groups that had received
the stem cells was significantly more favorable than the control group. In addition, the BM-
SCs group was significantly more favorable than the HUCSCs group (P<0.05).
Conclusion The results of this study suggest that both homograft BMSCs and het-
erograft HUCSCs may have the potential to regenerate peripheral nerve injury and
transplantation of BMSCs may be more effective than HUCSCs in rat.

Abstract
INTRODUCTION Transplantation of bone marrow stromal cells (BMSCs) or Schwann cells (SCs) can increase axonal regeneration in peripheral nerve injuries. Based on our previous investigations, the goal of the present work was to examine the individual and synergistic effects of the two different cell types in sciatic nerve injury. We pursued to evaluate the effects of BMSCs and SCs co-transplantation on the functional recovery after sciatic nerve injury in rat. METHODS In this experimental research, adult male Wistar rats (n = 32, 250-300g) were used, BMSCs and SCs were cultured, and the SCs were confirmed with anti S100 antibody. Rats were randomly divided into 4 groups (n = 8 in each group): 1-control group: silicon tube filled with fibrin gel without cells; 2-BMSCs group: silicon tube filled with fibrin gel seeded with BMSCs; 3-SCs group: silicon tube filled with fibrin gel seeded with SCs and 4-co-transplantation group: silicone tube filled with fibrin gel seeded with BMSCs and SCs. The left sciatic nerve was exposed, a 10 mm segment removed, and a silicone tube interposed into this nerve gap. BMSCs and SCs were transplanted separately or in combination into the gap. BMSCs were labeled with anti-BrdU and SCs were labeled with DiI. After 12 weeks electromyographic and functional assessments were performed and analyzed by one-way analysis of variance (ANOVA). RESULTS Electromyographic and functional assessments showed a significant difference between the experimental groups and controls. Electromyography measures were significantly more favourable in SCs transplantation group as compared to BMSCs transplantation and co-transplantation groups (p < 0.05). Functional assessments showed no statistically significant difference among the BMSCs, SCs and co-transplantation groups (p < 0.05). DISCUSSION Transplantation of BMSCs and SCs separately or in combination have the potential to generate functional recovery after sciatic nerve injury in rat. The electromyography evaluation showed a greater improvement after SCs transplantation than BMSCs or the co-transplantation of BMSCs and SCs.

Abstract
OBJECTIVE There is longstanding experimental and clinical evidence that supports the idea that replacement of dopaminergic (DAergic) neurons can ameliorate functional disabilities of Parkinson's disease (PD). The purpose of the present study is to examine the efficacy of transplantation of rat bone marrow stromal cell (BMSCs)-derived tyrosine hydroxylase-positive (TH(+)) cells induced by deprenyl into 6-hydroxydopamine (6-OHDA)-lesioned rat models, using behavioral tests and immunohistochemical evaluations. MATERIALS AND METHODS In this experimental study, undifferentiated BrdU-labeled BMSCs were incubated in serum-free medium that contained 10(-8) M deprenyl for 24 hours. Afterwards, BMSCs were cultured for 48 hours in α-minimal essential medium (α-MEM) supplemented with 10% FBS, then differentiated into TH(+) neurons. We randomly divided 24 hemiparkinsonian rats as follows: group 1 (control) received only medium, while groups 2 and 3 were injected with 2×10(5) BMSCs and deprenyl-treated cells in 4 µl medium. Injections were made into the injured strata of the rats. Rotational behavior in response to apomorphine was tested before transplantation and at 2, 4, and 6 weeks post-graft. Animals were then sacrificed, and the brains were extracted for immunohistochemical and electron microscopic studies. RESULTS Apomorphine-induced rotation analysis indicated that animals with grafted cells in groups 2 and 3 exhibited significantly less rotational behavior than those in the control group at 2, 4, and 6 weeks after transplantation. Immunohistochemical analysis demonstrated that BrdU-labeled cells expressed specific neuronal markers, such as NF 200 and TH, at the implantation site. The presence of TH(+) cells in conjunction with the reduction in rotation might show the capacity of grafted cells to release dopamine. Ultrastructural analysis revealed the presence of immature neurons and astrocyte-like cells at the graft site. CONCLUSION TH(+) neurons induced by deprenyl can be considered as a cell source for PD autograft therapy.

Abstract
Spinal cord injury (SCI) is a debilitating disease which leads to progressive functional damages. Because of limited axonal regeneration in the central nervous system, there is no or little recovery expected in the patients. Different cellular and molecular approaches were investigated in SCI animal models. Cellular transplantation of stem cells can potentially replace damaged tissue and provide a suitable microenvironment for axons to regenerate. Here, we reviewed the last approaches applied by our colleagues and others in order to improve axonal regeneration following SCI. We used different types of stem cells via different methods. First, fetal olfactory mucosa, schwann, and bone marrow stromal cells were transplanted into the injury sites in SCI models. In later studies, was applied simultaneous transplantation of stem cells with chondroitinase ABC in SCI models with the aid of nanoparticles. Using these approaches, considerable functional recovery was observed. However, considering some challenges in stem cell therapy such as rejection, infection, and development of a new cancer, our more recent strategy was application of cytokines. We observed a significant improvement in motor function of rats when stromal derived factor-1 was used to attract innate stem cells to the injury site. In conclusion, it seems that co-transplantation of different cells accompanies with other factors like enzymes and growth factors via new delivery systems may yield better results in SCI.
