Cardiomyocytes differentiated from human induced pluripotent stem cells(iPSCs)are valuable for the understanding/treatment of the deadly heart diseases and their drug ***,the very much needed homogeneous 3D cardiac differentiation of human iPSCs is still ***,it is discovered surprisingly that Rock inhibitor(RI),used ubiquitously to improve the survival/yield of human iPSCs,induces early gastrulation-like change to human iPSCs in 3D culture and may cause their heterogeneous differentiation into all the three germ layers(i.e.,ectoderm,mesoderm,and endoderm)at the commonly used concentration(10μM).This greatly compromises the capacity of human iPSCs for homogeneous 3D cardiac *** reducing the RI to 1μM for 3D culture,the human iPSCs retain high pluripotency/quality in inner cell mass-like solid 3D ***,the beating efficiency of 3D cardiac differentiation can be improved to more than 95%in~7 days(compared to less than~50%in 14 days for the 10μM RI condition).Furthermore,the outset beating time(OBT)of all resultant cardiac spheroids(CSs)is synchronized within only 1 day and they form a synchronously beating 3D construct after 5-day culture in gelatin methacrylol(GelMA)hydrogel,showing high homogeneity(in terms of the OBT)in functional maturity of the ***,the resultant cardiomyocytes are of high quality with key functional ultrastructures and highly responsive to cardiac *** discoveries may greatly facilitate the utilization of human iPSCs for understanding and treating heart diseases.
