Abstract
Satellite cell (SC) transplantation represents a powerful strategy to investigate SC biology during muscle regeneration. We described here a protocol for SC isolation from green fluorescent protein (GFP)-expressing mice and their transplantation into murine muscles. This procedure was originally used to assess the effects of the hormone unacylated ghrelin on muscle regeneration, in particular evaluating how the increase of unacylated ghrelin in the recipient muscle affected the engraftment of donor SCs (Reano et al., 2017).

Background
Skeletal muscle, which is composed of differentiated myofibers, can regenerate upon injury. Muscle regeneration relies on a population of quiescent resident stem cells called satellite cells (SCs) that reside beneath the basal lamina of the muscle fiber (Mauro, 1961). Upon injury, SCs undergo activation, extensive proliferation, differentiation, and fusion, eventually repairing or replacing the damaged myofibers (Collins et al., 2005).
Transplantation of SCs was considered for many years a potential therapy for Duchenne Muscular Dystrophy (DMD), since the engrafted myoblast can fuse with host myoblasts, suggesting the possibility of a functional repair in defective fibers (Partridge et al., 1978). Unfortunately, in human clinical trials in DMD patients, this strategy failed to restore dystrophin in injected muscles, and no functional improvements have been observed (Partridge, 2002). Nevertheless, SCs transplantation still represents a robust strategy to investigate SC biology, mainly to study both cell-autonomous and non-cell-autonomous mechanisms of muscle regeneration. In this protocol, we describe a method to transplant cells isolated from GFP-expressing donor mice that allow an easy tracking and measurement of engrafted cells in the recipient muscles. We used a simple and relatively inexpensive cell isolation method; however, cells to be transplanted can be isolated by different techniques, such as Fluorescence Activated Cell Sorting (FACS) or magnetic beads.
