Human UC-MSC transplantation promotes endothelial cell proliferation. a Ki-67 protein expression in single, twice, and thrice transplantation groups was detected by immunohistochemistry (400×). b Ki-67 mRNA expression in single, twice, and thrice transplantation groups was detected by qRT-PCR. GAPDH serves as an internal reference for qRT-PCR. *P < 0.05, **P < 0.01. MSC mesenchymal stem cell, TD8 transplantation day 8
