BACKGROUND Alopecia areata is the hair loss usually reversible, in sharply defined areas. The treatment of alopecia using growth factors shows interesting activity in promoting hair growth. In this concept, VEGF (vascular endothelial growth factor) is a marker of angiogenesis, stimulating hair growth by facilitating the supply of nutrients to the hair follicle, increasing follicular diameter. T...
The Arabidopsis (Arabidopsis thaliana) genome includes eight PIN-FORMED (PIN) members that are molecularly diverged. To comparatively examine their differences in auxin-transporting activity and subcellular behaviors, we expressed seven PIN proteins specifically in Arabidopsis root hairs and analyzed their activities in terms of the degree of PIN-mediated root hair inhibition or enhancement and...
Eclipta alba (L.) Hassk, Asiasarum sieboldii (Miq.) F. Maek (Asiasari radix), and Panax ginseng C. A. Mey (red ginseng) are traditionally acclaimed for therapeutic properties of various human ailments. Synergistic effect of each standardized plant extract was investigated for hair growth potential on nude mice, as these mutant mice genetically lack hair due to abnormal keratinization. Dried pla...
BACKGROUND Thuja orientalis has been traditionally used to treat patients who suffer from baldness and hair loss in East Asia. The present study sought to investigate the hair growth-promoting activity of T. orientalis hot water extract and the underlying mechanism of action. METHODS After T. orientalis extract was topically applied to the shaved dorsal skin of telogenic C57BL/6 N mice, the h...
The Wnt and Notch signalling pathways regulate hair follicle maintenance, but how they intersect is unknown. We show that Notch signalling is active in the hair follicle pre-cortex, a region of high Wnt activity, where commitment to hair lineages occurs. Deletion of jagged 1 (Jag1) results in inhibition of the hair growth cycle and conversion of hair follicles into cysts of cells undergoing int...
Human fibroblast?derived extracellular vesicles promote hair growth in cultured human hair follicles
Hair loss is a prevalent medical condition affecting both genders. In this study, we investigate the effects of specific class extracellular vesicles (EVs), namely human normal fibroblast-derived EVs (hFB-EVs), on dermal papilla (DP) and outer root sheath (ORS) cells examine molecular mechanisms responsible for hair growth in follicles (HFs). We find that Wnt3a, which maintains hair-generating ...
ABSTRACT Hirsutism is a difficult problem for both to the patients and the physicians. Its definition is subjective and the severity of hirsutism and the degree of acceptance are dependent on racial, cultural and social factors. The hair growth pattern, under the influences of genetic and ethnic factors, has significant variations among normal females. In order to determine the prevalence of h...
BACKGROUND Latanoprost is a prostaglandin analogue used to treat glaucoma. It can cause adverse effects, such as iridial and periocular hyperpigmentation, and eyelash changes including pigmentation and increased thickness, length, and number. Latanoprost has been used to treat eyelash alopecia, but knowledge on its effects on human scalp hair growth is not available. OBJECTIVE The primary obj...
INTRODUCTION Androgenetic alopecia (AGA) is the most common cause of hair loss among males, characterized by progressive thinning of the scalp hairs and defined by various patterns. The main factors underling hair loss in AGA are genetic predisposition and increased sensitivity of the hair follicles to androgens, leading to a shortening of the anagen phase. In the present study, the authors inv...
Receptor activator of NF-κB (RANK), known for controlling bone mass, has been recognized for its role in epithelial cell activation of the mammary gland. Because bone and the epidermo-pilosebaceous unit of the skin share a lifelong renewal activity where similar molecular players operate, and because mammary glands and hair follicles are both skin appendages, we have addressed the function of R...
