Abstract
The epidermis of developing feathers comprises outer and inner periderm, subperiderm and germinal layer. The inner periderm gives origin to sheath and barb ridge vane cells that contain alpha‐keratin and form a belt around feather filaments. This produces mechanical resistance, forcing the inner epidermal cell layers to fold inward and form barb ridges. Mesenchymal‐epidermal contacts occur from the mesenchymal core to external regions of barb...
