This study found that ectopic expression of Whn in transgenic mice caused impaired differentiation in epidermis and hair follicles, with hair growth defects and severe urinary tract issues leading to hydronephrosis.

This study found that proteomic analysis can distinguish hair samples across different ethnicities and body regions based on keratin protein levels, which may aid forensic hair identification.

This review discusses common skin appendage diseases, including their pathophysiology and treatments, but does not report new results.

This study demonstrated that engineered skin substitutes using human keratinocytes and murine dermal papilla cells can develop pigmented hairs without sebaceous glands, suggesting separate pathways for hair development and eruption.

In this study, synthetic vitamin D3 analogs stimulated hair growth and formation of normal hair follicles in nude mice, unlike the natural form 1,25 dihydroxyvitamin D3.

In this mouse study, researchers found that hydrogen peroxide and monoethanolamine in hair dyes may be key contributors to dermatitis and hair loss due to oxidative stress.

This study found that human scalp hair follicles can internally operate a Cori cycle, synthesize glycogen in the presence of lactate, and modulate growth through glycogen phosphorylase activity.

This study found statistically significant patterns in hair morphology and ultrastructure linked to biogeographic ancestry among European, African, and East Asian populations.

This study indicates that the OVOL1-OVOL2 axis may play a significant role in hair follicle differentiation and growth, potentially serving as therapeutic targets for hair disorders like alopecia and in the tumorigenesis of pilomatricoma.

This study found that unsaturated fatty acids are more abundant in the cortex of human hair than on its surface, and steryl glycoside-like lipids may help bind the cuticle to the cortex.

This study found that sonography and electron microscopy revealed distinct abnormalities in hair follicle morphology in patients with androgenetic alopecia, which may aid in diagnosing and managing the condition.

This study found that Wnt ligands from CD133-positive dermal papilla cells are essential for maintaining hair growth by supporting cell signaling between different hair follicle structures.

This study found that defective cross-linking in hair cuticles is observable in a minority of mouse hair mutants, suggesting different proteins are involved in cross-linking across cell types.

In human follicular cells, this study found that an Annurca apple-based dietary supplement may stimulate the production of hair keratins, suggesting potential benefits for hair growth.

This study found that hair loss in an Olmsted syndrome mouse model with a Trpv3 mutation was linked to premature keratinocyte maturation, affecting hair follicle structure and function.

This study found that CD99 is strongly expressed in the basal cells and hair follicles of normal adult and developing fetal skin, with expression patterns becoming similar after 20 weeks of gestation.

This article reviews the potential of topical minoxidil to cosmetically thicken hair in some individuals with male pattern hair loss, but it reports no new clinical results.

This study found that pelage abnormalities in Harlequin mutant mice are linked to severe AIF deficiency and associated with altered expression of genes related to hair structure.

This study concluded that the inner root sheath inhibits the expression of certain differentiation markers in hair bulbs, with calcium-induced changes paralleling those seen in hair follicle mid-segments.

The book discussed in this abstract is a comprehensive guide to hair analysis, detailing the latest methods and applications across various fields such as toxicology and drug monitoring, designed for both newcomers and experts in the field.

This review discusses the development and role of corneodesmosin in skin and hair follicle integrity, highlighting findings from mouse models and its connection to genetic diseases, with no new experimental results included.

The study developed a hair cream using extracts from plants like Hibiscus rosa sinensis and Nigella sativa, reporting that it may protect the scalp and hair by providing antimicrobial effects, promoting hair growth, and preventing hair fall and graying.

This study found that AP-2α and AP-2β transcription factors are crucial for maintaining adult skin homeostasis, with their inactivation in keratinocytes leading to impaired differentiation, hair abnormalities, and inflammation, highlighting their key regulatory roles.

This study utilized advanced imaging techniques to quantify hair damage and dye uptake dynamics, revealing that compound penetration in hair is influenced by molecule size and lipophilicity.

This review discusses the cornification process of epidermal keratinocytes in forming the skin barrier and reports no new results; it emphasizes the importance for diagnosis and treatment of skin disorders.

This study suggests that human hair follicles may operate their own Cori cycle, synthesizing glycogen from lactate under conditions of lactic acidosis.

In this study, the activation of Notch1 signaling in keratinocytes was found to play a key role in recruiting immune cells and facilitating skin repair after injury.

This study visualized mitochondrial metabolism in cultured bovine hair follicles and plucked human hairs, finding that ROS and mitochondrial polarization correlate in specific hair follicle regions, particularly near keratin deposition sites.

Hair from people with seborrheic dermatitis is thicker scaled, more damaged, and thinner than healthy hair, and atomic force microscopy can help monitor the condition.

This study found that expanding hair follicle keratinocytes with a fibroblast feeder followed by short-term coculture with dermal papilla cells could restore their ability to form new hair follicles.
