Abstract

Beginning with the first mitotic division in a Caenorhabditis elegans embryo, asymmetric cleavages establish much of the body plan. Although they share a common axis of polarity, at least three kinds of asymmetric cell division occur: two are under intrinsic control, while a third requires an inductive signal and may operate repeatedly throughout development.

摘要

从秀丽隐杆线虫胚胎的第一次有丝分裂开始，不对称分裂奠定了大部分的身体结构。尽管它们共享一个共同的极性轴，但至少发生三种不对称细胞分裂：两种受内在控制，而第三种需要诱导信号，并且可能在整个发育过程中反复起作用。
