Fig 1: Level of cardiomyocyte-like cell differentiation across the 4 groups. (A) Western blotting analysis of protein expression levels and (B) quantification of the results. The percentage increase in the protein expression levels of differentiation markers relative to control in the adipose-derived stem cells in the transparent group were as follows: GATA-4, 5.23%; Nkx-2.5, 5.66%; cTnT, 36.35%; desmin, 42.57%; Cx43, 5.78%. There were no differences observed in the expression of MyoD and a-SMA among groups. *P<0.05, **P<0.01 and ***P<0.001 vs. control group; #P<0.05, ##P<0.01 and ###P<0.001 vs. 5-aza-2'-deoxycytidine and laminin group; $P<0.05 and $$P<0.01 vs. white PHEMA group. Gata4, GATA binding protein 4; Nkx2.5, NK2 homeobox 5; cTnT, cardiac troponin T; Cx43, connexin-43; MyoD, myogenic differentiation; a-SMA, a-smooth muscle actin; PHEMA, poly-ß-hydroxyethyl methacrylate.
