  • Publication number: 20200121760
    Abstract: This invention describes methods for treating wound healing pathologies, inhibiting or reversing fibrotic skin disorders, including but not limited to keloids, atrophic and hypertrophic scars, and reversing skin aging via generating new dermal adipocytes (DAs). Methods described herein comprise (a) grafting of human hair follicles or (b) direct delivery of conditioned media from in vitro cultured hair follicles, or (c) delivery of purified individual factors secreted by hair follicles, or (d) delivery of small molecule agonists that mimic hair derived signaling activities, or (e) delivery of small molecule antagonists that inhibit anti-adipogenic programs, or (f) delivery of small molecule agonists of pro-adipogenic programs to convert endogenous wound or scar skin fibroblasts into new DAs.

  • Publication number: 20200101000
    Abstract: The present invention provides methods of treating baldness in a subject and generating new hair follicles, comprising epidermal disruption and administration of a compound that promotes a differentiation of an uncommitted epidermal cell into a hair follicle cell. The present invention also provides methods for hair removal and inducing hair pigmentation.

  • Publication number: 20200078351
    Abstract: DP-2 antagonists reversed PGD2-mediated human hair growth inhibition in a dose-dependent manner in vitro by reducing PGD2-triggered apoptosis and maintaining proliferation of keratinocytes. Hair follicles from approximately half of the alopecia patients exhibited little susceptibility to PGD2's effect in vitro. SNPs in the human DP-2 gene were identified that are associated with hair growth inhibition by PGD2. These findings underscore the role of DP-2 in regulating hair growth and indicate that DP-2 can be an effective approach in preventing and/or treating androgenetic alopecia in patients sensitive to PGD2. Furthermore, the SNPs identified here can be used to identify patients who will benefit from treatment.
