(a) A green fluorescence protein marker was used to determine the transfer efficiency of β-catenin knockdown in SHEDs (SHED-si). After transfection for 72 h, cells were observed under a (A) contrast phase microscope and an (B) immunofluorescence microscope. Scale bar, 100 μm. (b) qRT-PCR analysis was performed to detect β-catenin expression. (c) WB was conducted to determine β-catenin. (d) Quantification of β-catenin protein levels. vs. the control-si group.
