Hair Follicle - Physiology
Research News and Information
Definition of 'Hair Follicle'A tube-like invagination of the EPIDERMIS from which the hair shaft develops and into which SEBACEOUS GLANDS open. The hair follicle is lined by a cellular inner and outer root sheath of epidermal origin and is invested with a fibrous sheath derived from the dermis. (Stedman, 26th ed) Follicles of very long hairs extend into the subcutaneous layer of tissue under the SKIN. Common names: Hair Follicle; Follicle, Hair; Follicles, Hair; Hair Follicles |

Trp53 loss of function has previously been shown to rescue tissue maintenance and developmental defects resulting from DNA damage or DNA-repair gene mutations. Here, we report that p53 deficiency severely exacerbates tissue degeneration caused by ... Read more...
Circadian clock genes contribute to the regulation of hair follicle cycling.

Hair follicles undergo recurrent cycling of controlled growth (anagen), regression (catagen), and relative quiescence (telogen) with a defined periodicity. Taking a genomics approach to study gene expression during synchronized mouse hair follicle ... Read more...
6 Jul 2009 In view of the low loads of beta human papillomaviruses in skin samples, amounts of cellular DNA used in qualitative PCR may become limiting for virus detection and introduce variations in prevalence and multiplicity. This issue was explored within ... Read more...
