Bone marrow mesenchymal stem cell transplantation for treatment of cis-platinum-induced ovarian damage / 中国组织工程研究

BACKGROUND:Chemotherapy drugs can damage the ovarian function in women of childbearing age, and even lead to premature ovarian failure. Therefore, to improve and restore the ovarian function in patients has become an important issue. OBJECTIVE:To explore the therapeutic effect and feasibility of bone marrow mesenchymal stem cel therapy against chemotherapy-induced ovarian damage. METHODS:Rat models of chemotherapy-induced premature ovarian failure were established, and injected with PKH26-labeled bone marrow mesenchymal stem cels. At 15, 30, 45, 60 days after cel transplantation, five rats were selected respectively to detect folicle-stimulating hormone and estradiol levels, and then, the rats were kiled to take the right ovary for pathological examination. The number of ovarian folicles was detected under light microscope. At 30 days after cel transplantation, another two rats were selected to mate with male rats to observe the difference in the reproductive activity. RESULTS AND CONCLUSION:Four of 22 rats (18%) gradualy recovered their estrous cycle after cel transplantation, with the decreased folicle-stimulating hormone level and increased estradiol level. Moreover, the number of folicles was reduced. Al of these indicated that the ability to have children in rats was not damaged.These experimental findings suggest that bone marrow mesenchymal stem cels can partialy improve the ovarian function of rats under chemotherapy.

Expression of Ki-67 and estrogen receptor in the uterus of mice with autoimmune premature ovarian failure induced by peptide zona pellucida 3 / 南方医科大学学报

<p><b>OBJECTIVE</b>To investigate the histomorphology and the expressions of the proliferation marker Ki-67 and estrogen receptor in the uterus of mice with autoimmune premature ovarian failure (POF) induced by zona pellucida 3 peptide (pZP3).</p><p><b>METHODS</b>Autoimmune POP models were established in 20 female BALB/c mice (7-8 weeks old) by immunization with pZP3 and another 20 mice served as the control group. The POP models were verified by vaginal cytology, serum sex hormones, ovary histomorphology and ZP3 antibody immunohistochemistry. The histomorphology and expressions of Ki-67, estrogen receptor α and estrogen receptor β in the uterus of the mice were detected.</p><p><b>RESULTS</b>Autoimmune POP models were established successfully in 80% of the mice at 8 weeks after the immunization. Compared with those in the control group, the mice in the model group showed a smaller volume of the uterus, thinner endometrium and a reduced number of glands. The luminal epithelial cells, glandular epithelial cells and stromal cells in the uterus of the model mice all presented with a lower expression of Ki-67 than those in the control group, and Ki-67 translocation from the nuclei to the cytoplasm was found in the model group. The luminal epithelial cells, glandular epithelial cells and stromal cells showed positive ERα immunoreactivity in the model group but not in the control group. No obvious ERβ expression was found in the uterus in either of the groups.</p><p><b>CONCLUSION</b>pZP3 can induce autoimmune POP, cause suppressed proliferation of the endometrial epithelial cells and stromal cells, and reduce the cellular expression of ERα in the uterus of mice.</p>

Protective effect of lentivirus-mediated Bcl-2 gene transfection against phosphoramide mustard-induced apoptosis of human ovarian granulosa cells / 南方医科大学学报

<p><b>OBJECTIVE</b>To investigate the effect of lentivirus-mediated Bcl-2 gene transfection in protecting human primary ovarian granulosa cells against phosphoramide mustard (PM)-induced apoptosis.</p><p><b>METHODS</b>Granulosa cells were isolated from the follicle fluid of women undergoing in vitro fertilization and embryo transfer. The lentiviral vectors carrying Bcl-2 gene (pGC-FU-Bcl-2) and enhanced green fluorescence protein (pGC-FU-EGFP) were constructed and packaged into high-titer lentiviruses. The resulting recombinant lentivirus carrying Bcl-2 and EGFP genes or the empty vector were used to infect the primary human ovarian granulosa cells, followed by addition of PM in the cell culture, with untreated granulosa cells as the control. The cell apoptosis was detected by Annexin V and Hochst 33258 staining, and the expression of Bcl-2 protein was assessed using Western blotting.</p><p><b>RESULTS</b>The control granulosa cells showed an apoptotic rate of (1.93±0.28)%. The cells infected with pGC-FU-Bcl-2 prior to PM exposure had a apoptotic rate of (6.99±10.55)%, significantly higher than that of the control cells, but significantly lower than that of the cells with PM exposure only and those infected with the empty vector before PM exposure (P<0.05). The expression of Bcl-2 was the highest in the cells infected with pGC-FU-Bcl-2 prior to PM exposure (P<0.05).</p><p><b>CONCLUSION</b>Lentivirus-mediated Bcl-2 gene transfection can protect human ovarian granulosa cells against PM-induced apoptosis by upregulating Bcl-2 protein expression.</p>
