Abstract

The influence of accessory cells on the generation of neurons and neuronal survival has been studied in vitro using an immortalised, cloned cell line, Ast-1, which has many of the functional and phenotypic characteristics of cells of the astrocytic lineage. It was found that monolayers of Ast-1 cells were equivalent to monolayers of primary astrocytes in their ability to promote the generation of neurofilament positive neurons from neuroepithelial cells obtained from embryonic day 10 (E10) mice; and both were superior to NIH 3T3 cells. Ast-1 cell monolayers were also found to provide a suitable substrate for the prolonged survival (at least 3 days in vitro) of neurofilament positive neurons ..
