ESTABLISHMENT OF FUNCTIONAL CLONAL LINES OF NEURONS FROM MOUSE NEUROBLASTOMA*

AUTOR(ES)
RESUMO

Clonal lines of neurons were obtained in culture from a mouse neuroblastoma. The neuroblastoma cells were adapted to culture growth by the animal-culture alternate passage technique and cloned after single-cell plating. The clonal lines retained the ability to form tumors when injected back into mice. A striking morphological change was observed in the cells adapted to culture growth; they appeared as mature neurons, while the cells of the tumor appeared as immature neuroblasts.
