The chick dermis is known to control the formation of feathers and interfeathery skin in a hexagonal pattern. The evidence that the segregation of two types of fibroblasts involves Delta/Notch signalling is based on three facts. Rings of C-Delta-1-expressing fibroblasts precede and delimit the forming feather primordia. C-Delta-1 is uniformly expressed in the dermis of the scaleless mutant, which is almost entirely devoid of feathers. Feather development is inhibited by overexpression of C… CONTINUE READING
