To examine the correlations among the mRNA levels of OCT4, TGF-β RI, and migration-related genes, ectopic chocolate cyst and adenomyosis samples were collected and analyzed for mRNA expression levels of OCT4, TGF-β RI, SNAIL, SLUG, and TWIST, using the qRT-PCR method. Here, POU5F1 is linked to adenomyosis.
