Experiments on skin development in amniotes have shown conclusively that the pattern of cutaneous appendages is determined by the dermis. The following concept of feather pattern formation is proposed. The diameter of feather rudiments and the dermal

Collagen types I and III were purified from the skin of 3-or 7-week-old chickens, collagen type IV from bovine skin or EHS mouse tumour, fibronectin from human serum, and laminin from EHS mouse tumour. Antibodies were produced in rabbits or sheep, an

Spontaneous cutaneous wounds occur in avian embryos (chick, duck, quail) in various prominent parts of the body, notably the elbow, the knee and the outer face of feather buds. The frequency and size and the light and electron microscopic morphology

The shape, distribution, and orientation of peridermal cells were examined in the dorsolumbar skin of 7 1 2 - day chick embryos. Most feather rudiments of middorsal and lateral rows showed a marked cephalocaudal polarity. A similar polarity was found

Feet of chicks are normally covered with scales. Injection of retinoic acid into the amniotic cavity of 10-day chick embryos causes the formation of feathers on the foot scales. To elucidate whether retinoic acid affects primarily the epidermis or th

Two months after transplantation of human skin onto the nude mouse, excisional wounds were made through the entire thickness of the skin, at the center of the graft, using a 2-mm punch. At various time intervals thereafter, ranging from 2 days to 9 w

The distribution of glycosaminoglycans (GAGs) was studied in embryonic chick skin, using alcian blue staining with critical electrolyte concentration and glycanase treatment, immunofluorescence and transmission electron microscopy. Light microscopy r

A new approach in the understanding of the role of the two molting hormones, α- ecdysone and β- ecdysone , in disc development is described. A new culture medium has been developed which allows discs, with either hormone, to undergo all steps of me
