[Feather- and hair-forming properties of dermal cells of glabrous skin from bird and mammals].
The absence of cutaneous appendages in glabrous skin areas of birds and mammals rises from the incapacity of the dermis to trigger off the development of feather and hair buds. The dermal cells from avian or mammalian glabrous regions are however able to induce the continuation and completion of feather or hair morphogenesis respectively, provided the initiation of appendage bud formation has been triggered off by dermis from feather- or hair-forming regions.
