Developmental Dynamics, EarlyView.Abstract Neural crest cells are a transient cell population that emerges from the dorsal neural tube during neurulation and migrates extensively throughout the embryo. Among their diverse derivatives, glial cells (such as Schwann and satellite ganglionic cells) and melanocytes represent two major lineages. In vitro studies suggested they share a common

What controls melanogenesis? [PDF]
Experimental Dermatology, 1998 The pigments eumelanin and pheomelanin are the visually most striking products of specialized neural crest‐derived cells (melanocytes), and provide color to both epidermis and hair shafts. While the intriguing and controversial biological functions of these multifaceted heteropolymers will be discussed in a later feature, here it is explored how their ...

ENZYME LOCALIZATION DURING MELANOGENESIS [PDF]
The Journal of Cell Biology, 1969 The DOPA-reaction was used to identify tyrosinase in the nucleus and cytoplasm of the neural crest melanoblast of Taricha torosa, the California newt. In this urodele there is a nuclear DOPA-positive response during the normal embryonic development from the late blastula stage to the nucleus of the early melanocyte.
