Cardiogenic differentiation of mesenchymal stem cells on elastomeric poly (glycerol sebacate)/collagen core/shell fibers

Figure 7 Dual immunocytochemical analysis for the expression of mesenchymal stem cells marker protein CD 105 (A, D, G) and cardiac marker protein Actinin (B, E, H) in the co-culture samples and the merged image showing the dual expression of both CD 105 and Actinin (C, F, I); on the tissue culture plate (A, B, C), collagen nanofibers (D, E, F) and poly (glycerol sebacate)/collagen core/shell fibers (G, H, I) at 60 × magnification. Nucleus stained with 4,6-diamidino-2-phenylindole hydrochloride.
