How and when the regional competence of chick epidermis is established: feathers vs. scutate and reticulate scales, a problem en route to a solution.

The International journal of developmental biology - 1 Jan 2004

Prin Fabrice, Dhouailly Danielle

Abstract excerpt

Most of the chick body is covered with feathers, while the tarsometatarsus and the dorsal face of the digits form oblong overlapping scales (scuta) and the plantar face rounded nonoverlapping scales (reticula). Feathers and scuta are made of beta-keratins, while the epidermis of reticula and inter-appendage or apteria (nude regions) express a-keratins. These regional characteristics are determined in skin...
