Therapeutic efficacy of amniotic membrane stem cells and adipose tissue stem cells in rats with chemically induced ovarian failure

The present study was conducted to compare between the therapeutic efficacies of human amniotic membrane-derived stem cells (ham-mscs) vs. adipose tissue derived stem cells (ad-mscs) in cyclophosphamide (ctx)-induced ovarian failure in rats. forty-eight adult female rats were included in the study; 10 rats were used as control group. thirty-eight rats were injected with ctx to induce ovarian failure and divided into four groups: ovarian failure (iof) (iof group),iof + phosphate buffer saline (pbs group),iof + ham-mscs group and iof + ad-mscs group. serum levels of fsh and estradiol (e2) were assessed. histopathological examination of the ovarian tissues was performed and quantitative gene expressions of oct-4,stra8 and integrin beta-1 genes were conducted by quantitative real time pcr. results showed that iof and iof + pbs rat groups exhibited decreased ovarian follicles,increased interstitial fibrosis with significant decrease of serum e2,significant increase serum fsh level and significant down-regulation of stra8 and integrin beta-1. in ham-mscs and ad-mscs rat groups,there were increased follicles and corpora with evident the presence of oocytes,significant increase in serum e2,significant decrease in serum fsh levels (in ham-mscs treated group only) and significant up-regulation of the three studied genes with higher levels in ham-mscs treated rats group when compared to ad-mscs treated rats group. in conclusion,administration of either ham-derived mscs or ad-mscs exerts a significant therapeutic efficacy in chemotherapy induced ovarian insult in rats. ham-mscs exert higher therapeutic efficacy as compared to ad-mscs. © 2015.
