Spheroids of Bladder Smooth Muscle Cells for Bladder Tissue Engineering

Figure 5

Immunoblotting. The figure displays summarized representative bands and absolute protein concentrations normalized to GAPDH. Both SMC spheroids and 2D SMCs express the characteristic contractile marker proteins (α-SMA, calponin, smoothelin, and MyH11). Immunoblotting indicates that SMC spheroids quickly shift to a more differentiated phenotype than do 2D SMCs. , , , and . See figure S5 for representative bands for all time points.
