Ectodermal dysplasias form a large disease family with more than 200 members. The combination of hair and tooth abnormalities, alopecia, and cutaneous syndactyly is characteristic of ectodermal dysplasia-syndactyly syndrome (EDSS). We used a homozygosity mapping approach to map the EDSS locus to 1q23 in a consanguineous Algerian family. By candidate gene analysis, we identified a homozygous mut...
ABSTRACT The integrity of hair is determined by the intricate building blocks many layers follicle, but it also relies on proper nutrition. Weak can result from external factors such as physical trauma, heat manipulation, and chemicals, well internal inadequate A “hair diet” addresses both that lead to fragile or damaged provides basis for a conversation with patients improve health th...
OBJECTIVE To investigate the possible stimulating mechanism of Huoxue Bushen Mixture (HXBSM), a traditional Chinese compound medicine, on hair growth of mice via measuring the variance of skin blood vessel neogenesis and vascular endothelial growth factor (VEGF) expression in the hair follicle. METHODS Hot rosin and paraffin mixture depilation were used to induce C57BL/6 mice hair follicle to...
Activation of epithelial stem cells and efficient recruitment of their proliferating progeny plays a critical role in cutaneous wound healing. The reepithelialized wound epidermis has a mosaic composition consisting of progeny that can be traced back both to epidermal and several types of hair follicle stem cells. The contribution of hair follicle stem cells to wound epidermis is particularly i...
Several clinical research studies have demonstrated that chronic cutaneous wounds can be treated with hair follicle grafts. However, the clinical outcomes of hair follicle grafting compared to split-thickness skin grafting have not been examined. This study sought to compare the clinical outcomes of patients with chronic wounds following hair follicle therapy and split-thickness skin graft ther...
Keratins from the differentiating cortical cells of the guinea-pig hair follicle have been studied by immunological and immunofluorescent procedures. Antisera were prepared to the unfractionated keratin proteins from the follicle and the specificity of these antisera examined by lmmunodifTusion and lmmunoelectrophoresis. The major follicle antigens were the 'lowsulphur' keratins, and the antibo...
The hair-growth cycle is an example of a cyclic process that is well characterized morphologically but understood incompletely at the molecular level. As an initial step in discovering regulators in hair-follicle morphogenesis and cycling, we used DNA microarrays to profile mRNA expression in mouse back skin from eight representative time points. We developed a statistical algorithm to identify...
The murine hair coat consists of four different hair types that are characterised by hair length, the number of medulla columns, and the presence and number of bends. The molecular mechanisms underlying the establishment and maintenance of distinct hair follicle fates are unknown. We identify Igfbp5 as the first molecular marker that distinguishes among different hair follicle types. High-resol...
Ornithine decarboxylase (ODC) is the key enzyme in the synthesis of polyamines, small cationic molecules believed to have a role in many cellular processes such as cell migration, proliferation and differentiation. We show that ODC expression is associated with cell proliferation and commitment in hair follicle development and hair growth. In embryonic epidermis, ODC is expressed in ectodermal ...
Mammalian hair follicles are complex multicellular structures in the skin, which produce hair fibre under the influence of locally produced and systemic signalling systems. Investigation to determine mechanisms of regulation, follicular responses and the importance of nutritional supply have utilised a number of in vivo and in vitro approaches. Included in these are studies on isolated intact a...
