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

Figure 4 Cell proliferation study for days 5, 10 and 15 on tissue culture plate, poly (glycerol sebacate)/collagen core/shell fibers and collagen nanofibers using cardiomyocytes, mesenchymal stem cells and cardiomyocytes-mesenchymal stem cells co-culture. Denotes statistical significant difference MSC ^aP≤ 0.05 vs co-culture cells cultured on TCP and PGS/collagen core/shell fibers; Denotes statistical significant difference MSC ^dP≤ 0.01 vs co-culture cells cultured on collagen and PGS/collagen core/shell fibers. TCP: Tissue culture plate; PGS: Poly (glycerol sebacate); MSCs: Mesenchymal stem cells.
