During a woman's reproductive period, the endometrial tissue is shed and regenerated every month to prepare for pregnancy or for the next cycle. The aim of the present study was to isolate, culture and characterize human endometrial cells (ECs) derived from menstrual blood (MB) and the endometrium (E). MB‑derived ECs (MB‑ECs) were isolated from women's MB. E‑derived ECs (E‑ECs) were isolated from women's endometrial tissues. The present study investigated the epithelial cell marker cytokeratin 18 (CK18) in MB‑ECs and E‑ECs. Cell proliferation analyses indicated that E‑ECs (population doubling time, 20.85 h) grew faster than MB‑ECs (population doubling time, 22.05 h; P<0.05). Cell migration ability was found to be significantly greater for MB‑ECs than for E‑ECs at 48 h (P<0.01). MB‑ECs incubated with TGF‑β1 (3 ng/ml) exhibited significantly decreased CK18 mRNA expression (P<0.01), and significantly increased vimentin (Vim) mRNA (P<0.05) and protein (P<0.01) expression at 6 and 12 h, respectively. E‑EC incubation with TGF‑β1 (3 ng/ml) significantly decreased CK18 mRNA expression (P<0.01) at 12 h and significantly increased Vim mRNA (P<0.01) and protein expression (P<0.05) at 6 h. The present results indicated that MB‑ECs and E‑ECs were biologically different, and that epithelial‑mesenchymal transdifferentiation could be induced by TGF‑β1 treatment.
