Fibro-Adipogenic Progenitor Cells for Research Use
Bypass lengthy culture timelines by purchasing ready-to-use fibro-adipogenic progenitor (FAP) cells from the first and only commercial supplier.

Reliable cells from the most trusted name in muscle cell technology
Cook MyoSite is the first and only supplier to make purified human primary fibro-adipogenic progenitor (FAP) cells commercially available for research use. FAP cells are notoriously slow-growing and difficult to isolate, so we take care of that for you at our facility in Pittsburgh, Pennsylvania. Our laboratory is among the most well-equipped facilities worldwide for handling human muscle tissue and cell culture, which means your lab can count on receiving viable, uncontaminated, and reproducible cell products.


What are FAP cells?
- FAP cells are tissue-resident progenitor cells with ‘stem-like’ properties.
- These cells are dormant by default until acute injury of muscle fibers cause them to activate.
- In a variety of diseases, altered FAP cell responses are a major cause of muscle pathology and muscle loss.
- Current literature supports a role for these cells in the homeostasis and repair of multiple tissues suggesting that FAPs may have extensive therapeutic potential in the treatment of numerous diseases.
Our Guarantee
Reproducibility
Muscle cells are our core expertise, and our quality-controlled manufacturing process means no more worrying about consistent access to pure and uncontaminated cell cultures.
Dependability
Cook MyoSite manufactures each lot of FAP cells 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.
Characterization
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. These data ensure the provision of a well-defined primary starting culture to researchers.
Quality
Our production of quality FAP cell populations is backed by more than 20 years of 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.
