ABSTRACT
RESEARCH QUESTION Does adipose-tissue-derived stem cell conditioned medium (ASC-CM) supplementation enhance follicle and stromal cell outcomes in vitro? DESIGN:
Bovine ovaries (nâ¯=â¯8) were sectioned and cultured in vitro for 8 days in two different groups (i) standard culture (OT Ctrl D8); and (ii) culture with ASC-CM supplementation (OTâ¯+â¯CM D8). Half of the culture medium was replaced every other day, and stored to measure the production of oestradiol. Follicle classification was established using haematoxylin and eosin staining. Follicle and stromal cell DNA fragmentation was assessed by TUNEL assays, while growth differentiation factor-9 (GDF-9) staining served as a marker of follicle quality. Additionally, three factors, namely vascular endothelial growth factor (VEGF), interleukin 6 (IL-6) and transforming growth factor beta 1 (TGF-ß1), were evaluated in ASC-CM in order to appraise the potential underlying mechanisms of action of ASC.RESULTS:
The OTâ¯+â¯CM D8 group showed a significantly higher proportion of secondary follicles (Pâ¯=â¯0.02) compared with the OT Ctrl D8 group. The OTâ¯+â¯CM D8 group also demonstrated significantly lower percentages of TUNEL-positive follicles (Pâ¯=â¯0.014) and stromal cells (Pâ¯=â¯0.001) compared with the OT Ctrl D8 group. Furthermore, follicles in the OTâ¯+â¯CM D8 group exhibited a significant increase (Pâ¯=â¯0.002) in expression of GDF-9 compared with those in the OT Ctrl D8 group, and oestradiol production was significantly higher (Pâ¯=â¯0.04) in the OTâ¯+â¯CM D8 group. All studied factors were found to be present in ASC-CM. VEGF and IL-6 were the most widely expressed factors, while TGF-ß1 showed the lowest expression.CONCLUSIONS:
Addition of ASC-CM to culture medium enhances follicle survival, development and oestradiol production, and promotes the viability of stromal cells. VEGF, IL-6 and TGF-ß1 could be paracrine mediators underlying the beneficial effects.Palabras clave
