STEMdiff Cardio Maintenance Kit

Cardiomyocyte maintenance protocols for human pluripotent stem cell (hPSC) derivatives are supported by a serum-free workflow supplied by STEMCELL Technologies, formulated to preserve contractile activity and sarcomeric organization after the differentiation stage. The maintenance medium enables long-term culture of beating cardiomyocyte populations, sustaining expression of cardiac markers such as cTnT and α-actinin across multiple weeks of feeding cycles.

Typical downstream applications include in vitro cardiotoxicity screening, disease modeling using patient-derived iPSC lines, and electrophysiology characterization of ventricular-like and atrial-like cardiomyocytes. The kit ships as a multi-component system containing basal medium plus concentrated supplements; components should be stored frozen at -20 degrees C, with aliquots prepared upon first thaw to preserve activity across repeated experiments. Cultures are typically fed every 2 to 3 days to maintain consistent beating rates in well plates.

Researchers developing regenerative cardiac protocols, CRISPR-edited cardiomyopathy models, or high-throughput compound screens gain a defined maintenance medium that minimizes spontaneous dedifferentiation and supports reproducible sarcomere alignment. The product is intended for research use only and is produced under ISO-certified quality standards by STEMCELL Technologies.
