Cook MyoSite offers single-donor primary human skeletal muscle cells (skMDC) characterized by age, gender, race, and BMI with optimized media (MyoTonic, CryoTonic) to make cell culture growth, differentiation, and cryopreservation as reliable as possible in your lab. We offer cells from healthy donors and donors with a range of medical, neuromuscular, and other conditions.

At Cook MyoSite, our services are backed by nearly two decades of clinical experience in muscle-related research. skMDC are isolated and processed using only the highest quality materials, and our highly experienced Laboratory Research Services team provides expert customer service and technical support to ensure that the cells perform as expected.

Our Guarantee



Cook MyoSite, Inc., produces each lot of skMDC through a tightly controlled process using only high-quality materials to ensure consistent isolation of the muscle cells. These populations expand reliably in culture to experimentally relevant quantities, while maintaining their desired phenotype.



Cook MyoSite, Inc. only provides cell samples of the highest purity to researchers. The determination of purity is made via immunocytological analyses and/or flow cytometry of Desmin and Myosin Heavy Chain. Our company also offers the option of a gene expression profile. These data ensure the provision of a well-defined primary starting culture to researchers.



Our production of quality skMDC populations is backed more than 20 years’ experience in controlled cellular manufacturing at Cook MyoSite, Inc. Each lot is free of adventitious agents and is tested rigorously to ensure product consistency and performance.
