Gene expression changes in pOCs (line bars), pEpiE (white with black dots bars), and hEpiE (black with white dots bars) during the ECM-based scaffold repopulation process. Expression pattern of fibroblast-specific (VIM, and THY1), pluripotency-related (OCT4, NANONG, REX1, and SOX2), and granulosa-cell-associated (STAR, CYP11A1, CYP19A1, AMH, FSHR, and LHCGR) markers in freshly isolated pOCs and porcine and human untreated fibroblasts (T0), in fibroblasts exposed to 5-aza-CR (post 5- aza-CR), and at different time points of ECM-based scaffold repopulation (24 and 48 h and 7 days). (a), (b), and (c) indicate statistically significant differences (p < 0.05).
