1342 Spatial transcriptome profiling reveals TGFβ-2 in hair follicle progenitor cells is a potential driver of androgenetic alopecia

Re-activation of Wnt/β-catenin Signaling Pathway in Hair Follicle Stem Cells in Treatment of Androgenetic Alopecia

Hair loss is a common hair disorder in human population. It affects quality of life and there are ongoing attempts to find permanent treatment for this condition. But, today there is no completely safe and protective treatment for all. Hair follicle stem cells are alive, but quiescence in androgenetic alopecia and are potentially active and can proliferate and differentiate, then regenerate hai...

Androgenetic Alopecia

Nestin expression in hair follicle sheath progenitor cells.

The intermediate filament protein, nestin, marks progenitor cells of the CNS. Such CNS stem cells are selectively labeled by placing GFP under the control of the nestin regulatory sequences. During early anagen or growth phase of the hair follicle, nestin-expressing cells, marked by GFP fluorescence in nestin-GFP transgenic mice, appear in the permanent upper hair follicle immediately below the...

Prostaglandin D2 inhibits hair growth and is elevated in bald scalp of men with androgenetic alopecia.

Testosterone is necessary for the development of male pattern baldness, known as androgenetic alopecia (AGA); yet, the mechanisms for decreased hair growth in this disorder are unclear. We show that prostaglandin D(2) synthase (PTGDS) is elevated at the mRNA and protein levels in bald scalp compared to haired scalp of men with AGA. The product of PTGDS enzyme activity, prostaglandin D(2) (PGD(2...

Inflammation in androgenetic alopecia

Years of research have led to the conclusion that androgenetic alopecia may be a result of an alteration in the hair growth cycle and/or a premature aging of the pilosebaceous unit. The etiology of androgenetic alopecia has been defined as multifactorial or even polygenic in nature. The fact that the success rate of treatment with either antihypertensive agents or modulators of androgen metabol...
