Core Tip
Core tip: Nutrient supplements were screened for improving cell survival during the cardiomyocyte differentiation process of human embryonic stem cells (hESC) and human induced pluripotent stem cells (hiPSC) in a serum-free medium based on the inhibition of p38 MAPK (SB media). Soy hydrolysate and bovine serum albumin supplementation was found to improve cell viability and therefore increased the yield of HES-3 cardiomyocytes by 2.6-fold over non-supplemented SB medium. The enhancing effect of this medium was demonstrated in an additional hESC line (H1) and Siu1-hiPSC cell line (15 and 9 fold respectively). The cardiomyocytes formed expressed canonical cardiac markers (sarcomeric α-actinin, myosin heavy chain and troponin-T) and demonstrated all three major phenotypes: nodal-, atrial- and ventricular-like.
