Abstract
The phagocytic ability of satellite cells has long been a matter of dispute. Doinikow (1913), Behnsen (1927), Tschetschujeva (1930), and Nawzatzky (1933) found that particulate vital dyes accumulate in the satellite cells of the mouse, whereas the findings of De Castro in the cat (1932) and Brizzee in the chick (1949) were negative. Nageotte (1907c, d) in his early papers on the transplantation of spinal ganglia, attributed to the satellite cells the capacity to fragment and engulf degenerated neurons (neuronophagia). Instead, other authors (Marinesco 1907a, b, c; Schaffer 1910; De Castro 1921; Cajal 1928; Kuntz and Sulkin 1947a, b) denied the phagocytic activity of the satellite cells though maintaining that these cells are able to destroy degenerated neurons by releasing lytic enzymes. In a recent systematic study of the spinal ganglia of the chick embryo, Pannese (1978) found that satellite cells, identified on the basis of their relationship with the normal neuroblasts and basal lamina, are able to fragment and engulf degenerating neuroblasts (Figs. 29, 30). This result, as well as incidental observations made on developing ganglia (see, e.g., Tennyson 1970) and some findings obtained in ganglia of adult animals (see, e.g., Herman et al. 1973, Aldskogius and Arvidsson 1978), seems to lend support to the view originally advanced by Nageotte (1907c, d).
