Translational research aiming to improve survival of ovarian tissue transplants using adipose tissue-derived stem cells.

There is now sufficient evidence to support the feasibility and efficacy of ovarian tissue (OT) cryopreservation and transplantation for both fertility preservation and restoration purposes. However, there are still issues to address regarding the grafting procedure itself, since transplanted tissue suffers massive follicle loss in the early post-grafting period. To improve follicle survival after transplantation, our group recently developed a two-step transplantation technique for OT transplantation in a xenografting model using adipose tissue-derived stem cells (ASCs). The aim of this narrative review is to describe and discuss the previously reported findings. ASCs were initially characterized by flow cytometry as positive for CD29, CD44, CD73, CD90, CD105 and CD166 (>95%) and negative for CD34, CD14, CD31, CD45 and Lin1. ASCs were used in a model of xenotransplantation, were they were embedded in a fibrin scaffold and transplanted to the peritoneum of immunodeficient mice. The goal of the first step was to increase levels of partial pressure of oxygen (pO
