Making a face: A new and earlier marker of neural crest development

... and non-neural cell layers. "We show in this work that neural crest stem cell precursors are designated very early in development -- as early as the gastrula stages -- and in an independent fashion from those other tissues," said Martín García-Castro . The researchers grew grafts of cells from "stage ...
