L'École de Nogent: the contributions of Etienne Wolff and Nicole Le Douarin

Charles Galperin*

Paris, France

ABSTRACT We retrace here the foundation of the "Nogent School". What were its main scientific orientations? Two fields of research dominated Etienne Wolff's work: Experimental Teratology and Intersexuality. Nicole Le Douarin's work , in one sense, started with a remarkable tool which is the quail / chick marker system. She applied this system to the study of in vivo migration of cells during embryonic life, i.e.neural crest cells and lymphoid progenitors. This article revisits some of these fundamental aspects.
