Figure 4 Transplanted Human Cells Induce Neoangiogenesis in the Infarcted Heart

(A) Representative images of CD31 immunostaining in the peri-infarct and the infarct regions of hearts transplanted with CD56⁺CD34^–CD144^– cells, CD56^–CD34⁺CD144⁺ cells, and CD56⁺CD34⁺CD144⁺ cells. Scale bars = 100 µm. (B) Hearts transplanted with CD56⁺CD34⁺CD144⁺ cells display a higher capillary density within the infarct when compared with the other groups (*p < 0.05, CD56⁺CD34⁺CD144⁺ vs. CD56⁺CD34^–CD144^– and CD56^–CD34⁺CD144⁺; p < 0.05, all cell groups vs. phosphate-buffered saline [PBS]).
