Regional distribution and time course of mitotic activity of astroglia in the immature mouse forebrain.

Abstract

The regional distribution of mitotic figures in the immature mouse forebrain was mapped at various early postnatal periods up to P12, to determine the regional time courses of early postnatal cell proliferation. Mitotic figures seen outside the germinal layers appeared to be astroglial precursors; their postnatal proliferation was found to follow a well-defined regional programme.
