Hair growth cycle. Hair development is a continuous cyclic process and all mature follicles go through a growth cycle consisting of growth (anagen), regression (catagen), rest (telogen) and shedding (exogen) phases (Figure 3).Furthermore, therapeutic agents that target distinct phases and hormones involved in the hair cycle may be useful for promoting hair growth.

Huxley’s layer of inner root sheath hair matrix. actively dividing area of the hair bulb that produces the hair. connective tissue root sheath. derived from dermis but a bit denser, surrounds epithelial root sheath. epithelial root sheath. Extension of the epidermis lying adjacent to hair root. Widens at deep end into bulge—source of stem cells for follicle growth. Apr 20, 2024 · hair follicle: [noun] the tubular epithelial sheath that surrounds the lower part of the hair shaft and encloses at the bottom a vascular papilla supplying the growing basal part of the hair with nourishment — see hair illustration. Many growth factors and receptors important during hair follicle development also regulate hair follicle cycling. 3,4 The hair follicle possesses keratinocyte and melanocyte stem cells, nerves, and vasculature that are important in healthy and diseased skin. 5-7 To appreciate this emerging information and to properly assess a patient with hair ... In the present report, we demonstrate label-free visualization of hair follicle stem cells in mouse whiskers by multiphoton tomography due to the intrinsic fluorophores such as NAD(P)H/flavins. We compared multiphoton tomography of GFP-labeled HAP stem cells and unlabeled stem cells in isolated mouse whiskers. The Hair Follicle Bulge Hair follicle stem cells are cells with the potential to generate new hairs and potent
