Knockdown of β-catenin in MSCs. a The transfected MSCs were screened with puromycin (at 10 µg/mL). Only the cells transduced by lentivirus survived. The dead cells did not contain lentivirus. b, c After a week, the living cells formed clones. d The β-catenin mRNA expression in β-catenin-knockdown MSCs was compared with the control group and the nontarget group by qPCR. Scale bar 100 µm
