Distinct pattern of embryonic expression of the sea urchin CyI actin gene in Tripneustes gratilla.

abstract：:Early embryonic cells are capable of acquiring numerous developmental fates until they become irreversibly committed to specific lineages depending on intrinsic determinants and/or regional interactions. From fertilization to gastrulation, such pluripotent cells first increase in number and then turn to undergoing dif...
