Quantitative PCR results of miRNAs in differentiated and undifferentiated BMECs. a: Cellular miRNAs of BMECs. b: miRNAs in BMEC culture media. c: The miRNA expression ratio of medium/cells. ⁺ P < 0.10; * P < 0.05, ** P < 0.01, and *** P < 0.001 indicate differences between BMEC cultures with (DIP+) and without lactogenic hormones (DIP−) for each of the miRNAs
