Figure 6: (a) Expression of Nkx2.5 and MyoD in MDSC-EMT and iPS-EMT. Both MDSC-EMT and iPS-EMT expressed Nkx2.5 (green) and MyoD (red) transcription factors at the protein level. Scale bar indicates 20 μm. (b) Distribution of Nkx2.5 and MyoD positive cells in EMT. The majority of cells expressed both Nkx2.5 and MyoD. DN denotes double negative cells. * by Chi-square test.
