An in vitro assay to quantify satellite cell activation using isolated mouse myofibers.

Isolated myofibers offer the possibility of in vitro study of satellite cells in their niche. We describe a mouse myofiber isolation assay to assess satellite cell activation by quantifying myofiber-derived satellite cell progeny. The assay allows isolation of myofibers from a mouse using standard equipment and reagents. It can be used to compare satellite cells across different mouse models or to evaluate their response to treatments, offering a valuable complementary tool for in vitro experimentation.
