[Quantitative microcinematographic analysis of interactions between sensory nerve cells and cutaneous tissues in vitro: demonstration of a difference in the behavior of nerve fibers with respect to dermal and epidermal cells].

Dynamic and morphometric analysis of interactions between sensory nerve cells and cutaneous tissue of 7 day Chick embryos in co-culture show that nerve endings behave differently when interacting with dermis of epidermis. In particular, nerve fibers display a deviation reaction in the proximity of epidermis.
