This study found that while epidermal PLCγ1 is not necessary for keratinocyte differentiation in interfollicular epidermis, it is crucial for normal hair and sebaceous gland formation in mice.

In this study, Dsc 1 was highly expressed in certain layers of fetal epidermis and hair follicle but not in basal cells or oral mucosa, indicating its potential role in maintaining epithelial integrity.

This study found that hair germ and epidermal basal cells differ in keratin expressions in rat hair tissues, with hair-specific keratins appearing after the differentiation of each layer.

This study found that mutations in phosphorylation sites on the PIN3 protein disrupt its phosphorylation and subcellular trafficking, affecting auxin transport and root growth in a cell-type-specific manner.

This study concluded that GLCAT14A-C genes are crucial for the function of glucuronic acid transfer to AGPs in Arabidopsis, affecting various growth and reproductive traits such as seed germination and root hair growth.

This study found that during dialysis, lower plasma-potassium levels were associated with hyperglycemia, suggesting potassium correction is vital when using glucose-rich dialysate.

This study identified a missense mutation in the keratin 71 gene as the cause of autosomal dominant woolly hair/hypotrichosis in a Japanese family, marking the first human mutation in KRT71 linked to a hair disorder.

This study found that nestin-expressing progenitor cells, capable of becoming ORS keratinocytes, are present in both developing and adult mouse hair follicles.

This study found a strong positive correlation between vascular endothelial growth factor expression and microvessel density in the hair follicles of Liaoning cashmere goats during different fetal periods.

In this review, researchers reported that pyroptosis, a type of inflammatory cell death linked to inflammasome activity, is a key factor in the pathogenesis of alopecia areata and may present new therapeutic opportunities, though most treatments are still in early research stages.

This study observed distinct changes in the ultrastructure of Hexi cashmere goat hair follicles throughout the year, highlighting stages with specific cellular and structural characteristics.

This study found that integrin alpha-6 and p63 may play a role in hair loss, with variable expression patterns in different types of alopecia observed in scalp biopsy samples.

This study found that arbuscular mycorrhizal fungus inoculation and shading improved tea seedlings' growth, nutrient absorption, and stress resistance by enhancing root biomass and regulating phytohormone levels and gene expression.

This article integrates existing literature on hair follicle structure and formation at the cellular and molecular level, reporting no new findings.

This study found that overexpression of PKCα in mouse epidermis increases expression of specific proinflammatory mediators and induces inflammation but does not significantly affect epidermal differentiation, proliferation, or tumor promotion with TPA.

In this study, researchers found that p75 neurotrophin receptor signaling affects apoptosis during hair follicle regression in mice, and altering its activity might help manage disorders involving early catagen entry.

This review discusses the historical, legal, and clinical aspects of electrolysis and thermolysis, highlighting potential risks due to the lack of standardized training for electrologists in the United States, but reports no new clinical results.

Growth factors can either promote or inhibit hair follicle cell growth and collagen breakdown.

A missing mK6irs1 gene causes hair loss in mice.

This study found that the orphan protein Plet-1 is expressed in specific keratinocytes of mouse hair follicles and may regulate keratinocyte interactions with inert tissues by affecting migration and adhesion.

This review discusses methods for evaluating hair growth-promoting effects of candidate substances for androgenetic alopecia, focusing on cell assays, organ cultures, and animal models, and reports no new results.

This study concludes that loose anagen hair can develop in adulthood and may be difficult to distinguish from telogen hair loss, with pathologic findings offering limited diagnostic insights.

This case report describes dermoscopic features of pemphigus vulgaris on the scalp, highlighting that hair casts may suggest treatment adjustment for improved disease control.

This chapter reviews the anatomy and physiology of hair follicles but reports no new research findings or clinical results.

This study reports that a homozygous A1103G mutation in DSG 4 is responsible for localized autosomal recessive hypotrichosis in a 2-year-old Chinese girl, resulting in reduced DSG 4 expression and hair defects.

In this animal study, pigs on a biotin-deficient diet showed significant hair loss, weak and brittle claws, and skin lesions after 8–10 weeks, with tissue necrosis observed microscopically after 15 weeks.

This study found that injecting keratin into the skin of mice promoted hair growth, potentially through keratin's interaction with hair-forming cells and changes in the microenvironment.

In this study, UVB exposure was found to alter certain chemical properties of the hair shaft, such as keratin components and water content, without significantly affecting its physical morphology.

This study suggests that ADAM 10 and 12 proteases may play important roles in the regulation of hair cycling through their expression patterns in hair follicle structures.

This study successfully developed 3D hair follicle organoids from neonatal mouse epidermal and dermal cells, showing structural and molecular resemblance to native anagen hair follicles.
