Fig. 2From: Sfrp1 protects against acute myocardial ischemia (AMI) injury in aged mice by inhibiting the Wnt/β-catenin signaling pathwayIn vivo effects of Sfrp1 on histology and cardiac function of aged mice with acute myocardial infarction (AMI) (a) The infection efficiency of AAV-Sfrp1 was examined by immunoblotting. b Cardiac histopathological changes evaluated by HE staining. c-f Cardiac function evaluated by echocardiography. *P < 0.05, **P < 0.01, compared to the control group; #P < 0.05, ##P < 0.01, compared to the NC group or M3 group; &&P < 0.01, compared to the M7 groupBack to article page
