Re: Re: GB --> FR precuticular epithelium

[Guest guest]

Bonjour Nath, Bonjour Sue,

I was thinking along the same lines after finding this, although it sounds

strange for a diagram. Pre- in the sense of precursor?

*Microanatomical changes in the hair follicle epithelium and mesenchyme

during the hair cycle.* In telogen hair follicle, epithelial cells of the

secondary hair germ are located immediately above the follicular papilla. In

late anagen hair follicle, the onion-shaped follicular papilla is surrounded

by epithelial hair bulb containing germinative cells that differentiate into

six cell populations and form the hair shaft and the inner root sheath. In

catagen hair follicle, follicular papilla returns into the ball-shaped

quiescent state and keeps integrity with cells of the regressing epithelial

strand (Stenn and Paus, 2001).

FWIW,
