Spermatogenesis after transplantation of adipose tissue-derived mesenchymal stem cells in busulfan-induced azoospermic hamster
نویسندگان
چکیده مقاله:
Objective(s): Adipose tissue-derived mesenchymal stem cells (AT-MSCs) with more potent immunomodulatory effects, greater proliferative potential and secretion of growth factors and cytokines in comparison with bone marrow derived MSCs are more appropriate for cell therapy. The aims of the present study were to evaluate the histomorphometric effect of AT-MSCs allotransplantation on regeneration of germinal layer cells of seminiferous tubules in busulfan-induced azoospermic hamsters.Materials and Methods: In the present experimental case-control study, AT-MSCs were isolated from adipose tissue of two female and six male donor albino hamsters, and testes of the males were simultaneously used as negative control group. Six mature male recipient hamsters received two doses of busulfan with three weeks interval to stop endogenous spermatogenesis. Right testis of hamsters was intratubular injected with AT-MSCs via efferent duct 35 days after induction of azoospermia and was used as cell therapy group. The left testis without cell therapy was served as azoospermia group.Results: After 35 days, testes and epididymis in all groups were removed for histological evaluation. Histomorphometric analyses of AT-MSCs-treated testes and epididymis showed that the epithelial tissue of seminiferous tubules was normally repaired in most cell-treated seminiferous tubules, and spermatozoa were present in epididymis tubes in comparison with intact testes. The untreated seminiferous tubules and epididymis tubes of azoospermia group were empty.Conclusion: Allotransplanted AT-MSCs could successfully induce spermatogenesis in azoospermic seminiferous tubules of hamster. Therefore, AT-MSCs can be suggested as an attractive candidate in cell transplantation of azoospermia.

BACKGROUND Bone marrow-derived mesenchymal stem cells (BM-MSCs) have potential of differentiation and they secrete anti-inflammatory cytokines and growth factors which make them appropriate for cell therapy. AIM OF THE WORK Were to evaluate the healing effect of BM-MSCs transplantation on germinal cells of busulfan-induced azoospermic hamsters. MATERIAL AND METHODS In the present experiment...

Evaluating the Viability of Adipose Tissue-derived Mesenchymal Stem Cells in Diabetic Culture Media Model
Introduction: In diabetes mellitus, stem cells are exposed to inappropriate conditions such as an increase of glucose in extracellular space, oxidative stress, and deprivation from growth factors (following ischemia). This study was aimed to evaluate the effect of these conditions on stem cells. Methods: Stem cells were isolated from subcutaneous adipose tissue of rats. The cells were maintaine...

Due to their favorable intrinsic features, including engraftment, differentiation, and immunomodulatory potential, adult mesenchymal stem cells (MSCs) have been proposed for therapeutic in utero intervention. Further improvement of such attributes for particular diseases might merely be achieved by ex vivo MSC genetic engineering previous to transplantation. Here, we evaluated for the first tim...

BACKGROUND Mesenchymal stem cells (MSCs) are ideal candidates for treatment of diseases. Amniotic membranes are an inexpensive source of MSCs (AM-MSC) without any donor site morbidity in cell therapy. Adipose tissue derived stem cells (ASCs) are also suitable cells for cell therapy. There is discrepancy in CD271 expression among MSCs from different sources. In this study, the characteristics...

Background: During radiation therapy, stromal cells surrounding the tumor (e.g mesenchymal stem cells) may affect the treatment outcomes. We aimed to investigate the effects of gamma radiation on the mRNA expression of cytokines, DNA damage and population doubling time (PDT) of adipose-derived mesenchymal stem cells (ASCs). Material and methods: ASCs were enzymatically extracted from breast tis...
