Effects of transplanted adipose tissue on intimal and vasa vasorum neovascularization. a Immunostaining for CD31 was performed to evaluate intraplaque angiogenesis. b Statistical analysis for a (n = 6). **p < 0.01 compared with sham group, ^##p < 0.01 compared with PVAT group. c Immunostaining for CD31 in another mouse in PVAT group, suggesting markedly neovascularization and thrombus organization. d Vasa vasorum neovascularization of the mice in PVAT group
