Effects of manually and automatically isolated CD133⁺ stem cells on formation of infarction scar. 1 × 10⁵ CD133⁺ stem cells were intramyocardially transplanted into SCID bg mice after myocardial infarction (MI). Three weeks after cell transplantation infarction size (a) and infiltration of the infarcted scar with new blood vessels (b) were analyzed. For control untreated infarction (MIC) and SHAM operation were used. Data are presented as mean ± SEM. *p ≤ 0.05; **p ≤ 0.01; ***p ≤ 0.001 vs. MIC; ns not significant
