  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.
