Primordial Germ Cells in Mammals,germ cell lineage, or germline, provides the only biological link, the only route of genetic transmission, from one generation to the next. Unlike somatic cell lineages, the germline is potentially immortal. For reproduction, for heredity, for development and for evolution, germ cells are of fundamental importance.

Mapping of Gastrulation Movements in Birds,y a demonstration of the procedure for preparing the germs. This procedure is derived from that of New (1955). Its main characteristic is that it allows normal development in vitro for a 24 hour period in laid blastoderms that are cultivated with their ventral side up, towards the observer.

,Hensen’s Node: The Amniote Equivalent of Spemann’s Organizer,lip is now widely referred to as “Spemann’s organizer”. In the early 1930’s, C.H. Waddington demonstrated that amniote embryos (ducks, chicks and rabbits) could also be made to generate a second nervous system by transplanting the tip of the primitive streak, a region known as Hensen’s node (Waddington, 1932; 1933).
