Postnatal satellite cells, isolated from normal or previously denervated skeletal muscles of juvenile quails, were tested as to their capacity to participate in embryonic muscle ontogeny. They were grafted into 2-day chick embryo hosts, in place of a piece of brachial somitic mesoderm. Satellite cell implants were prepared from pellets either of freshly isolated cells or of cells precultured in vitro under proliferative conditions. Myogenic capacity of the implanted cells was attested by their ability to fuse into myotubes when cultured under differentiation conditions. In no case did the implanted satellite cells invade the adjacent wing bud or participate in wing muscle morphogenesis. They did not either give rise to myotubes at the site of implantation, nor did they even survive longer than 3 days in the embryonic environment. These negative results indicate that postnatal satellite cells, unlike embryonic myoblasts, are unable to take part in muscle embryogenesis. Although they derive from the same somitic myogenic cell line as the embryonic myoblasts, they therefore represent a differentiated non-totipotent type of myogenic cell.
