The regenerative potential of cardiac patch was evaluated in a rat MI model. Infarction was surgically induced by occluding the distal left anterior descending coronary artery (Figure 3A), then one monolayer cardiac patch and one omentum patch were sutured over the site of infarction in animals from the patch group (n=6) (Figure 3B). One omentum patch was sutured over the injury site in animals from the control group (n=6) (Figure 3C), while animals in the MI group recovered without either experimental treatment. After four weeks, the survival rate of patch group and control group were 100% and 83.3% respectively. Human Nuclear Antigen (HNA) and human Troponin T positive staining were noted in the histological assessment 4 weeks after surgery (Figure 3D-E: HNA,F-G: Troponin T). The scar areas of the infarction in both groups were evaluated as previously described (Takagawa et al. 2007). The average percentage of scar area in the patch group was significantly lower than that of control group (mean ± SD of 10.6 ± 5.1% and 19.39 ± 8.1% respectively, p = 0.048) (Figure 4 A-C).
