Abstract
Hair follicles display a unique pattern of cyclic growth and regression involving cell proliferation, differentiation and migration. The molecular details of these processes are largely unexplored. Global expression analyses on the basis of about 20,000 genes for each morphologically distinguishable stage of the hair cycle revealed unexpected complexities of and major temporal shifts in transcriptional programs involving about 13% of all genes. In particular, hundreds of genes characterise the pattern of genomic activity during regression and resting phases; selected genes can be used to monitor hair growth in mice. We demonstrate that temporal expression patterns predict gene expression domains within the hair follicle. Expression of insulin-like growth factor binding proteins and anti-angiogenic factors is associated with the regression phase of the hair cycle.
