Abstract
Primary myoblasts can be isolated from mouse muscle cell extracts and cultured in vitro. Muscle cells are usually dissociated manually by mincing with razor blades or scissors in a collagenase/dispase solution. Primary myoblasts are then gradually enriched by pre-plating on collagen-coated plates, based on the observation that mouse fibroblasts attach quickly to collagen-coated plates, and are less adherent. Here, we describe an automated muscle dissociation protocol. We also propose an alternative to pre-plating using magnetic bead separation of primary myoblasts, which improve myoblast purity by minimizing fibroblast contamination.
