  Satellite cells (SC) constitute the stem cell population of skeletal muscle and conduct myogenic growth and differentiation. Recently, aldehyde dehydrogenase 1 (ALDH1) has been identified as a novel myogenic factor in experimental models of SCs. ALDH1 constitutes a subfamily of the ALDH enzyme super family. The enzymatic functions of ALDH1 isoforms include both protection against oxidative stress products and regulation of differentiation as pacemaker enzyme in retinoic acid signaling. Although ALDH enzymatic activity has been demonstrated in SCs it is not clear which isoforms are important in human skeletal muscle. Here, we show that ALDH1A1 and ALDH1A3 are expressed in human SCs. Using antibodies directed against ALDH1 and its isoforms ALDH1A1 and ALDH1A3, respectively, we demonstrate immunohistochemical staining in peri-fascicular position matching the localization of SCs.
