A Review on the Activity of Angiogenic and Apoptotic Factors in Transplanted Ovarian Tissue
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 to reach a follicle to preovulatory stage and to set up a network between granulosa cells and blood vessels through the theca layer. Up to the first 3 days after transplantation and reanastomosis start, a large number of follicles especially advanced types, begin an early death due to their severe dependence on nutrients of blood supply. Loss of the nutritional sources of granulosa cells leads to a decrease in survival and supporting factors and thus, cell death increases. Considering the importance of this issue, the present study intends to investigate the activity of angiogenic and apoptotic factors in transplanted ovarian tissue
