Studies on the differentiation of egg envelopes. I. The starfish, Astropecten aurantiacus.

abstract：:Cellular dedifferentiation underlies topical issues in biology such as regeneration and nuclear cloning and has common features in plants and animals. In plants, this process characterizes the transition of differentiated leaf cells to protoplasts (plant cells devoid of cell walls) and is accompanied by global chromat...
