YAP dysregulation triggers hypertrophy by CCN2 secretion and TGFβ uptake in human pluripotent stem cell-derived cardiomyocytes.

Hypertrophy Cardiomyopathy (HCM) is the most prevalent hereditary cardiovascular disease - affecting >1:500 individuals. Advanced forms of HCM clinically present with hypercontractility, hypertrophy and fibrosis. Several single-point mutations in b-myosin heavy chain (MYH7) have been associated with HCM and increased contractility at the organ level.

The effects of xeno-free cryopreservation on the contractile properties of human iPSC derived cardiomyocytes.

Human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) have advanced our ability to study the basic function of the heart and model cardiac diseases. Due to the complexities in stem cell culture and differentiation protocols, many researchers source their hiPSC-CMs from collaborators or commercial biobanks. Generally, the field has assumed the health of frozen cardiomyocytes is unchanged if the cells adhere to the substrate and commence beating.
