Direct observation in vitro of how neuroblasts migrate: medulla and cochleovestibular ganglion of the chick embryo.

The hypothesis that neuroblasts migrate in the nervous system by a locomotory process was tested experimentally. An in vitro preparation permitted direct observation of postmitotic cells migrating from the rhombic lip of the medulla and the anlage of the cochleovestibular ganglion. Cell locomotion was not seen. Instead migration was produced by elongation… CONTINUE READING
