Androgenetic alopecia is often treated by follicular unit transplantation, a technique that involves minimal risk of hair loss because of the more resistant nature of the donor area. Lichen planopilaris is a cicatricial alopecia that causes permanent destruction of hair follicles. We report two cases of post-transplantation lesions compatible with lichen planopilaris in both recipient and donor...

Sip1 is a member of the family of two-handed zinc finger/ homeodomain proteins identified as a DNA binding transcriptional repressor interacting with receptor-activated SMADs. SMADs are intracellular signal transducers activated by binding of TGFb/BMP ligands to their receptors and are involved in the control of cellular functions of embryonic development and tissue homeostasis. During mouse an...

Vellus hair follicle Accessory auricle Trichofolliculoma Hair nevus Abstract We present a case of hair follicle nevus, a rare hamartoma composed of vellus hair follicles. Hair follicle nevus should be differentiated from accessory auricle, trichofolliculoma and hair nevus.

Background: The cold-induced inflammation of cryotherapy mayalter the immunologic processes and structural components ofthe hair follicles responsible for AA. The aim of this study was tostudy the efficacy of cryotherapy in alopecia areata, and totalis.Method: Forty-four patients with recalcitrant scalp alopeciaareata or totalis were treated with cryotherapy. The cryo-systemchosen was a closed ...

Growth factors are involved in the regulation of hair morphogenesis and cycle hair growth. The present study sought to investigate the hair growth promoting activities of three approved growth factor drugs, fibroblast growth factor 10 (FGF-10), acidic fibroblast growth factor (FGF-1), and basic fibroblast growth factor (FGF-2), and the mechanism of action. We observed that FGFs promoted hair gr...

Introduction: Adult stem cells are the group of cells which conserve their nature in tissues and organs among other cells. In recent years, the researchers reported the existence of stem cells on the Bulge of hair follicles near to the smooth muscle. It is possible to differentiate these stem cells to neural cells by induction of Shh, FGF, and RA factors. Because of existence of these factors ...

Previous work has implicated the Myc-binding transcription factor Miz1 in the control of keratinocyte proliferation and in the cellular response to TGFbeta. Miz1 is expressed in basal keratinocytes of the interfollicular epidermis and in hair follicles. Here we have conditionally knocked out the POZ/BTB transactivation domain of Miz1 in keratinocytes using a keratin 14 (K14)-Cre mouse deleter s...

Cellular hair growth therapy is an emerging approach to alopecia. Recently, Tsuboi et al. (J Am Acad Dermatol. 2020;83,109–116.) have observed hair-growth stimulation by dermal-sheath-cup cells in patients with androgenic Hair follicle-associated pluripotent (HAP) stem cells, originate the bulge area and express nestin, been shown differentiate multiple cell types including keratinocytes, neuro...

background and objective: rosacea is a common and ill-defined disease and demodex folliculorum has been reported in rosacea in a number of clinical studies. since demodex mite is present in many healthy individuals, the mite may have a pathogenic role only when it is present in high densities. therefore, in this study, the possible role of demodex folliculorum and the importance of mite density...
