The effect of KLF5 knockdown on the differentiation of chicken SMSCs. The SMSCs were transfected with KLF5 siRNA or negative siRNA and cultured in differentiation medium for subsequent experiments. The myotube formation of cells transfected at 24 h, 48 h, and 72 h was observed under a light microscope. Red arrows indicate myotubes. Black scale bar=100 µm.
