Effects of growth factors on hair follicle cell proliferation and release of collagenolytic factors

摘要

The present invention relates to methods for detecting the effects of selected growth factors and pharmaceuticals on the growth and development of hair follicles by assaying hair follicle cell proliferation and cellular collagenolytic factor secretion. In particular, isolated hair follicle cells maintained as intact functioning folliculoids are embedded in a three-dimensional culture system, and exposed to the chemical agent of choice. The effect of this agent can then be determined with respect to its ability to modify cellular proliferation or secretion of proteolytic factors. Each determination involves the use of a separate assay.
