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.

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.
