Figure 3. Quantitative Reverse transcriptase polymerase chain reaction analysis shows the expressions of stemness markers (A), (B) mRNA expression levels of Oct4 and Sox2 (C) granulosa cell morphology from passage 0 (P0), passage 1 (P1), and passage 4 (P4). ***P < 0.001 (P0) vs. P1 and P4, **P < 0.01 (P1) vs. P4.
