Fig 4. Transplantation of CM with GH increased newly formed vasculature.

(A) Cardiac sections were stained with von Willebrand factor (vWF), and angiogenesis was evaluated in PBS, GH, CM+PBS, and CM+GH groups. The number of vWF-positive cells was increased in the CM+GH group. Bars are 200 μm. (B) vWF-positive cells were counted in the central and peripheral portions of the infarcted area. The transplantation of CM and GH significantly increased angiogenesis in both areas. (* P<0.05)
