Abstract excerpt
1. As previously reported, ectodermal a4-2 blastomeres isolated from 8-cell embryos of the ascidian, Halocynthia roretzi or aurantium, and cultured under conditions of cleavage arrest always differentiated into an epidermal phenotype, showing long-lasting Ca(2+)-dependent action potentials and/or tunic on the cell surface. a4-2 blastomeres contacted by a chordamesodermal blastomere, A4-1, differentiated into a...
