COMPARISON OF THERAPEUTIC EFFECTS OF DIFFERENT METHODS OF ADMINISTRATION OF MEZENCHIMAL STEM CELLS TO MICE WITH PREMATURE OVARIAN INSUFFICIENCY

Premature ovarian insufficiency (POI) is condition of female hypogonadism. One of the reasons for the development of POI is anticancer chemotherapy. Currently, hormone replacement therapy is considered the most effective method of treatment POI, which, however, had a number of side effects, requires constant administration of pharmaceuticals, did not restore fertility and correct pathological changes in target organs. Therefore, the search for alternative methods of treatment based on the use of stem cells is promising. The aim of work was to compare the therapeutic effects of different methods of administration of mesenchymal stem cells isolated from adipose tissue (AT MSCs) in restoring sexual function, as well as the behavior of mice with chemotherapy-induced premature ovarian failure. Materials and methods. The investigation was carried out on BALB/c mice with a POI model induced by Cyclophosphamide and Busulfan. A histological examination of preparations of the ovaries and uterus was carried out. We studied the changes in the weight of mice, ovarian function, sexual activity, as well as the behavior of animals in anxiolytic and zoosocial tests after treatment with AT MSCs with intraperitoneal and intraovarian routes of administration. Results and discussion. It was shown that the effectiveness of the use of AT MSCs depends on the method of their administration at the treatment of POI induced by chemotherapy. More rapid and complete restoration of the morphological structure, sexual function, and behavioral responses were observed in mice with POI treated by intraovarial administration of AT MSCs.
