EFFECT OF CONDITIONED MEDIA FROM GLIAL CELL CULTURES ON THE REPRODUCTIVE SYSTEM OF FEMALE RATS OF DIFFERENT AGES
Keywords:ovaries, sex hormones, conditioned environment, glial cell culture, neurotrophic factors, cryopreservation
Conditioned media from stem/progenitor cell cultures are a valuable source of growth factors for restoring ovarian function, inhibiting their premature aging, and preventing age-associated pathological changes in oocytes.
The aim of this work was to study the effect of conditioned media obtained from intact and cryopreserved cultures of glial cells on the structural and functional characteristics of the ovaries, the levels of the sex and gonadotropic hormones in rats of different ages. The experiments were carried out on females aged 6 (reproductive age, RA) and 14 months (late reproductive age, LRA). A monolayer culture in which glial cells predominated was obtained from the dorsal root ganglia of neonatal piglets. Cells were cryopreserved in the presence of 7.5% cryoprotectant dimethyl sulfoxide. Conditioned media from intact (ICM) and cryopreserved (CCM) cultures were fractionated by ultrafiltration and fractions up to 30 kDa were obtained. The ICM and CCM fractions were injected into rats intraperitoneally. The estrous cycle, the levels of gonadotropic and sex hormones, the histological structure of the ovaries and the quantitative composition of the follicles were studied.
ICM and CCM had a stimulating effect on the release of primordial follicles from the dormant state in the ovaries of RA and LRA animals, while the intraovarian follicular pool was rearranged with a decrease in the number of follicles of hormone-independent developmental stages (primordial and primary) and an increase in the number of atretic follicles. The introduction of ICM and CCM promoted an increase in the LH/FSH ratio and inhibition of the formation of age-associated cysts in LRA rats. The biological effect of CCM on the reproductive system of female rats was similar to that observed with the use of ICM.
