Many changes of female reproductive system are based on the vascular activity and blood flow. In ovarian follicular development, re-anastomosis is critical and permits cells and oocytes to utilize nutrients as well as the hormones. Moreover, it plays a main role in corpus luteum formation. Female reproductive system undergoes several angiogenesis programs which are considered essential in order...
Background Fertility preservation for female cancer patients prior to cancer therapy has emerged as an essential component of comprehensive patient care. In the US, approximately 6% of women diagnosed with invasive cancer between 2007 and 2011 that were under 45 years old. The incidence of cancers in reproductive age women signifies a need for fertility preservation options and this need is inc...
BACKGROUND This study was designed to assess the impact of different ovarian tissue transplantation sites on the follicular pool and ovarian tissue integrity after short-term grafting, since there is no consensus in the literature as to the optimal grafting site in experimental models. METHODS Frozen-thawed ovarian tissue from eight patients was grafted for 1 or 3 weeks to the peritoneum, ins...
Ovarian injury because of chemotherapy can decrease the levels of sexual hormones and potentia generandi of patients, thereby greatly reducing quality of life. The goal of this study was to investigate which transplantation method for human umbilical cord mesenchymal stem cells (HUMSCs) can recover ovarian function that has been damaged by chemotherapy. A rat model of ovarian injury was establi...
BACKGROUND Previous studies showed that immature oocytes stored in ovarian tissue could develop to the mature stage after transplantation. However, the quality and competency of the oocytes developed in xenografted ovarian tissue have never been investigated. As a pilot study to investigate this uncharted issue, we evaluated microtubule organization and chromatin configuration of human oocytes ...
Human amnion epithelial cells (hAECs) transplantation via tail vein has been reported to rescue ovarian function in mice with chemotherapy-induced primary ovarian insufficiency (POI). To test whether intraperitoneally transplanted hAECs could induce therapeutic effect and to characterize the paracrine effect of transplanted hAECs, we utilized a chemotherapy induced mice model of POI and investi...
