text_1: Addition of BMP4, activin A, CHIR99021, and SU504 to reprogramming fibroblasts generates, expands and maintains cardiovascular progenitor cells (CPCs)
text_2: These induced expandable cardiovascular progenitor cells (ieCPCs) proliferated extensively for more than 18 passages in chemically defined conditions, with 10(5) starting fibroblasts robustly producing 10(16) ieCPCs.
