Melatonin and the hair follicle
Journal of Pineal Research, 2007Abstract: Melatonin, the chief secretory product of the pineal gland, has long been known to modulate hair growth, pigmentation and/or molting in many species, presumably as a key neuroendocrine regulator that couples coat phenotype and function to photoperiod‐dependent environmental and reproductive changes.

Hair follicle predetermination
Journal of Cell Science, 2001Recent genetic and molecular studies of hair follicle (HF) biology have provided substantial insight; however, the molecular data, including expression patterns, cannot be properly appreciated without an understanding of the basic cellular rearrangements and interactions that underpin HF cyclic transformations.

It is fashionable to refer to man as a naked ape, meaning a hairless ape. This witty designation, however, is completely wrong, since we are certainly not hairless and we are not apes. We are abundantly supplied with hairs, but most of them are barely visible to the naked eye. Quantitatively, we probably have as many hairs in our skin as furry animals.

Hair Follicle Regeneration by Transplantation of a Bioengineered Hair Follicle Germ
2016Hair follicle morphogenesis is first induced by epithelial-mesenchymal interactions in the developing embryo. In the hair follicle, various stem-cell populations are maintained in specialized niches to promote repetitive hair follicle-morphogenesis, which is observed in the variable lower region of the hair follicle as a postnatal hair cycle.

Localized hair follicle hamartoma
Journal of Cutaneous Pathology, 1993A 4‐year‐old male presented with an indurated papular plaque on his right nasolabial fold. The lesion, present since the child was a few months of age, progressively extended in a band‐like fashion up to the upper lip. Microscopically, there was almost complete replacement of the hair follicles by trichoepithelioma‐like epithelial proliferations ...

Seminars in Cell & Developmental Biology, 2007
The increasing use of the hair follicle as a stem cell paradigm is due in part to the complex interplay between epithelial, dermal and other cell types, each with interesting differentiation potential and prospective therapeutic applications. This review focuses on research into the environmental niche, gene expression profiles and plasticity of hair ...

Hair follicle kinetics in psoriasis
British Journal of Dermatology, 1976The rate of epidermal cell production has been measured in the various parts of scalp hair follicles in patients with psoriasis of the scalp, and in controls with normal scalp skin. An in vitro technique was used in which thin tissue slices were exposed to tritiated thymidine enabling cells about to divide to become autoradiographically labelled ...

Minoxidil Sulfation in the Hair Follicle
Skin Pharmacology, 2009The in vivo model which may be the most accurate for the ability to predict hair growth in humans, and which was utilized in the preclinical development of minoxidil, is the adult stumptailed macaque. Previous reports have suggested that the enzyme activity which accounts for the activation of minoxidil, i.e., minoxidil sulfotransferase, is present in ...

IMMUNOPATHOLOGY OF THE HUMAN HAIR FOLLICLE
Dermatologic Clinics, 1999Although patients are told that, in many instances, their hair loss is precipitated by stress, they are certainly stressed and saddened by their alopecia. They would be elated with the ability to regrow their hair. Ideally, therapy would be specific and targeted at the cascade of inflammatory, cytokine-mediated, and mesenchymal events which lead to ...

Optimization of hair follicle spheroids for hair-on-a-chip
Biomaterials ScienceWe report spheroids prepared by injecting LEF1 and Wnt1 into DPCs via transfection and then adding KCs and HUVECs. Through SEM, we observed a part extending outward from the TK and TKH surfaces, as indicated by white arrows.
