Definition of 'Delamination'

From: GCIDE
  • Delamination \De*lam`i*na"tion\, n. (Biol.) Formation and separation of lamin[ae] or layers; one of the methods by which the various blastodermic layers of the ovum are differentiated. [1913 Webster]
  • Note: This process consists of a concentric splitting of the cells of the blastosphere into an outer layer (epiblast) and an inner layer (hypoblast). By the perforation of the resultant two-walled vesicle, a gastrula results similar to that formed by the process of invagination. [1913 Webster]
