Abstract

The mechanisms underlying neural and epithelial specification in the blastoderm are under constant study. Growth factors of several kinds participate in this specification process but also they affect the proliferation of blastoderm cells and apoptosis. In this work we analyze the distribution of cell death and the pattern of cell proliferation in early chick embryos and evaluated how these cellular processes are governed by growth factors.
