Reciprocal signaling between the mesenchymal condensations and the placode leads to formation of mesenchyme-derived dermal papilla inside the epithelial envelope. The dermal papilla functions as a signaling center during initial hair morphogenesis in the embryo, as well as during the adult hair cycle. The dermal papilla transmits signals to the surrounding epithelium, maintaining its proliferation and differentiation into the various cell types of the growing hair shaft.
Rows of papillae protruding from the dermis into the epidermis form ridges that create patterns on the skin of the hands, feet, and body. These papillary ridges on the fingertips are responsible for fingerprints.These ridges develop sometime before birth.he dermal papillae are small, nipple-like protrusions of the dermis that reach into the epidermis, bringing food and oxygen to the lower layers of epidermal cells. In additio â¦ n, a papilla nourishes every hair follicle.
