SUMMARY

Clear and dark satellite cell classes were identified by electron microscopy in the lumbar sensory ganglia of domestic fowl in 8 pre and 4 post-hatching stages of development. Some cytologic differences found between the two classes relating to the rough-endoplasmic reticulum, ribosomes, Golgi apparatus and junctional complexes suggest the existence of distinct functional features for both types of satellite cells.

RESUMO

Foram identificadas, por microscopia eletrônica, células satélites claras e escuras em gânglios sensitivos lombares do galo doméstico, em 8 fases pré e 4 fases pós-eclosão. Algumas diferenças citológicas encontradas, referentes ao retículo endoplasmático rugoso, ribosomos, aparelho de Golgi e complexos juncionais, sugerem a existência de características funcionais distintas para ambos os tipos de células satélites.
