The species of extracellular ATP can participate the effect of nerve system not only as the neurotransmitter and modulator but also has a trophic action to glial cell and neuron. It participates in many courses, e.g. cell differentiation and apoptosis, the morphologic change of chondriosome, to stimulate the synthesis and release of cytokine and nerve growth factor. It has a great influence to neurological growth and plasticity.

Methods We established the model of human hair follicle in vitro in Williams E serum-free medium. We can continuously observe morphologic change of hair follicle under an invert microscope. The length of hair follicle was measured by eyepiece micrometer and DNA synthesis rate of human hair follicle in vitro by measuring the rates of incorporation of 3H-TdR.Histology form was observed by Cryo-section and transmission electron microscope.
