Abstract
Adult skeletal muscle stem cells, termed satellite cells, are essential for regenerating muscle after tissue damage. Satellite cells are located in a specialized microenvironment between muscle fibers and their surrounding basal lamina. This local niche serves as a compartment to preserve satellite cell function and provides signals that facilitate the rapid response to injury. Visualization of this local niche enables the elucidation of such niche-derived signals. Here, we describe techniques for isolating single myofibers with their associated satellite cells for ex vivo visualization and analysis of an intact muscle stem cell niche.
