Abstract

Embryonic stem (ES) cells are pluripotent stem cells derived from a developmental stage of pre‑implanted embryos. The present study investigated the effect of female sex steroid hormones on the characteristics of human ES cells by using a feeder‑free culture protocol. In a feeder‑free condition without sex hormones, human ES cells assumed the form of tightly packed cells that grow in a monolayer. The cells had clean and defined edges with no evidence of differentiation and expressed several markers specific for undifferentiated ES cells including POU class 5 homeobox 1 (POU5F1), sex determining region Y‑box 2 (SOX2) and NANOG homeobox (NANOG). It was then investigated if female sex steroid hormones including 17β‑estradiol (E2) and progesterone (P4) altered the protein expression of epithelial-mesenchymal transition (EMT) associated markers in addition to pluripotency markers including POU5F1, SOX2 and NANOG in human ES cells. The protein expression levels of N‑cadherin, Snail and Slug were increased while E‑cadherin expression was decreased by treatment of E2 or P4, and the expression levels of POU5F1, SOX2 and NANOG were decreased by the treatment of E2 or P4. When E2 and P4 were treated in combination with an estrogen receptor inhibitor (ICI 182,780) and progesterone receptor inhibitor (RU486) respectively, their effects on EMT and pluripotency of ES cells were restored to control levels. The results suggested that E2 and P4 may regulate EMT and pluripotency of human ES cells by mediating their receptors. The present study may aid in the understanding of the role of sex steroid hormones in the cellular biology of human ES cells.
