Robust cardiomyocyte differentiation from RhiPSCs in fully chemically defined conditions. (a) Schematic of cardiomyocyte differentiation protocol from RhiPSCs. The differentiation stages and media were shown above and under the arrows and timeline, respectively. MEF-CM, MEF conditioned medium; CDBM, cardiac differentiation basal medium. (b) Immunofluorescence staining (top panels) and FACS analysis (bottom panels) for cardiac markers: cTnT, MYH, and α-ACTININ at day 10 of differentiation. Nuclei were stained by DAPI (blue). Scale bars, 50 µm. (c) Cardiac differentiation efficiency on different matrices (Matrigel, VTN-N, and Synthemax). Representative immunofluorescence staining for α-ACTININ and NKX2.5 (left panels) and flow cytometry analysis for cTnT (right panel) (data are mean ± SEM, n = 3). Nuclei were stained by DAPI. Scale bars, 50 µm. (d) Cardiac differentiation efficiency, assessed by cTnT expression via flow cytometry, of 8 unique RhiPSC lines on Synthemax-coated plates (data are mean ± SEM, n = 3).
