The Hair Follicle as a Dynamic Miniorgan [PDF]

Current Biology, 2009
Hair is a primary characteristic of mammals, and exerts a wide range of functions including thermoregulation, physical protection, sensory activity, and social interactions. The hair shaft consists of terminally differentiated keratinocytes that are produced by the hair follicle.

3D Numerical Simulation of Hair Formation Process Using a Particle Model [PDF]

, 2015
Hair is very important in determining human appearance. Although there are numerous observed data and experimental recordings for hair, a detailed mechanism of hair formation has not yet been elucidated.

Expression profile of long non-coding RNA in inner Mongolian cashmere goat with putative roles in hair follicles development

Frontiers in Veterinary Science, 2022
The hair follicle is a complex skin accessory organ, which determines hair growth. Long non-coding RNAs (lncRNAs) have been proven to play an important role in hair follicle development, but their specific mechanism is still unclear.

Ginsenoside CK inhibits androgenetic alopecia by regulating Wnt/β‐catenin and p53 signaling pathways in AGA mice

Food Frontiers, 2023
Androgenetic alopecia (AGA) is one of the most common chronic skin diseases caused by the destruction of androgens in the body. It is caused by the excessive deposition of dihydrotestosterone around the hair follicle, resulting in hair follicle atrophy ...

Serpins in the Human Hair Follicle [PDF]

Journal of Investigative Dermatology, 2000
Proteinases and their inhibitors are very likely to function as mediators or regulators of the hair growth cycle. Very little information is currently available, however, regarding the specific inhibitors present in human hair follicles at defined stages of their growth cycle.

Self-organizing & stochastic behaviors during the regeneration of hair stem cells [PDF]

, 2011
Stem cells cycle through active and quiescent states. Large populations of stem cells in an organ may cycle randomly or in a coordinated manner. Although stem cell cycling within single hair follicles has been studied, less is known about regenerative ...

Ratchet effect for nanoparticle transport in hair follicles [PDF]

, 2016
The motion of a single rigid nanoparticle inside a hair follicle is investigated by means of Brownian dynamics simulations. The cuticular hair structure is modeled as a periodic asymmetric ratchet-shaped surface. Induced by oscillating radial hair motion

Pre-aggregation of scalp progenitor dermal and epidermal stem cells activates the WNT pathway and promotes hair follicle formation in in vitro and in vivo systems

Stem Cell Research & Therapy, 2019
Background Billions of dollars are invested annually by pharmaceutical companies in search of new options for treating hair loss conditions; nevertheless, the challenge remains.

Plucked human hair shafts and biomolecular medical research [PDF]

, 2013
The hair follicle is a skin integument at the boundary between an organism and its immediate environment. The biological role of the human hair follicle has lost some of its ancestral importance.

Rosmarinus officinalis Essential Oil Increases Hair Length and Follicle Diameter of Ultraviolet B-exposed Mice Through VEGF

Indonesian Biomedical Journal, 2023
BACKGROUND: Ultraviolet (UVB) radiation induces hair photoaging by triggering oxidative stress, causing alterations in hair diameter and length, which contribute to the development of senile alopecia.
