Fig. 4From: Tissue-engineered cardiac patch seeded with human induced pluripotent stem cell derived cardiomyocytes promoted the regeneration of host cardiomyocytes in a rat modelQuantitative comparison of the cellular infiltration into the scaffold and α-actinin positive cell. a There was no statistical difference between the groups in the cell number within the scaffolds at 16 weeks after implantation. b The area fraction of positively stained α-actinin cells was significantly higher in the seeded group than in the unseeded group. *: p < 0.05Back to article page
