Initial infarction size and human ECFC retention rate in rat ischemic myocardium. a Diagram of experimental schedule. b–d Initial infarction size and AAR 1 day post IRI with PBS or ECFC + MPC injection (n = 5; mean ± SEM). e Luciferase-labeled ECFC retention rate at 1 day, 1, 2 week post-IRI with PBS or ECFC + MPC injection (n = 4; mean ± SEM). Normal data from healthy rat hearts served as a negative control (n= 3; mean ± SEM). Numbers above bars are P values
