The study suggests that abnormal activation of hair follicle stem cells and Wnt10b/β-catenin signaling may contribute to the development of sebaceous neoplasms.

This review discusses the varied roles of Wnt7a in development, tissue homeostasis, and cancer, reporting no clinical results; the authors emphasize the need for further investigation on its roles in inflammation and fibrosis.

This study found that keratoacanthoma of the lip likely arises from outer root sheath cells, based on the presence of specific keratin markers and periodic acid-Schiff staining patterns.

This study used single-cell RNA sequencing to create a detailed atlas of human scalp hair follicles and found that early-stage hair graying involves matrix hair progenitor depletion linked to P53 pathway activation.

The document explains what healthy skin, nails, and hair look like on an ultrasound.

This chapter reviews the use of electrospun matrices in creating tissue-engineered skin substitutes and reports no new clinical results; it emphasizes the need for a cell-friendly microenvironment.

This review discusses the mechanisms, applications, and research evidence of photobiomodulation, highlighting its efficacy, safety, and potential for standardized evaluation methods, but reports no new clinical results.

This study demonstrates that a novel autologous hair follicle-derived epithelial sheet can effectively repigment skin in patients with stable vitiligo, offering a potential new treatment option.

In this study, researchers examined androgen receptor activity in the adult mouse brain and found specific expression in key brain areas, which could inform understanding of cognitive side effects in humans undergoing androgen deprivation therapy for prostate cancer.

In this study, researchers identified hair follicle stem cells in the bulge region of canine hair follicles, suggesting potential applications for future translational research.

In this study, the authors concluded that a hydrolyzed eggwhite protein treatment promoted the reconnection of disulfide bonds in excessively bleached hair, after reduction and oxidation processes in permanent waving.

This review discusses drug repositioning for cardiometabolic disorders and reports no new clinical findings; the authors emphasize its potential benefits, such as known safety profiles and reduced development costs compared to new drug development.

This chapter reviews various mucocutaneous manifestations of endocrine disorders and provides illustrative images of these clinical features, but reports no new research findings.

This study reported that fermented grapeseed oil may enhance hair permeability and improve strength and color retention in chemically treated hair compared to regular grapeseed or silicone oils.

In this study, trichocytes were shown to have potential for alternative differentiation, with mesenchymal cell influences playing a critical role in determining this process.

In this study, researchers used atomic force microscopy to capture and analyze morphological changes in the surface of healthy hair, identifying features such as pitting and rod-shaped macro-fibrillar elements, which could inform future research on hair conditions and care.

This anatomical study on Eclipta alba concluded that unique secretory structures in stems and leaves may serve as identifying features of the plant and the Asteraceae family.

This paper reviews the surface degradation of hair and describes how combining 18-MEA with specific surfactants can maintain hydrophobicity on bleached and weathered hair surfaces.

This study found that the binding and release of BMP-2 from kerateine biomaterials are significantly influenced by pH and salt concentration, highlighting the potential for developing improved bone repair systems.

This study reported that patients with alopecia areata have reduced expression of the melanocortin receptor MC2R in their scalp tissues compared to normal scalp, indicating potential involvement in the condition's pathophysiology.

In this study, researchers analyzed hair from different regions of Malvi cattle and found significant variations in color, shape, and band pattern, although the medullary index remained consistent between 0.50 and 0.60 across the samples.

The 15th-century Korean mummy's hair was well-preserved due to a protective lime-soil coating.

This study found that human epidermal keratinocytes express a functional μ-opiate receptor at both the mRNA and protein levels, potentially playing a role in skin physiology and pathology.

This study identified a domain on human chromosome 21q22.1 containing various high glycine-tyrosine and high sulfur keratin-associated protein genes, revealing their diverse expression in hair-forming cells.

The connective tissue around hair follicles changes structure throughout the hair cycle.

This study identified and characterized a gene called 4C32, which is expressed in the periderm of embryonic mouse skin and has a structure similar to keratin-associated proteins.

In this study, NuMA's microtubule-binding domain was found to be crucial for correct spindle orientation and skin differentiation, with its loss leading to neonatal lethality in mice.

This review synthesizes the diverse roles of the transcription factor LHX2 in development, tissue maintenance, and injury repair across various organ systems, highlighting its potential therapeutic applications and significance in regenerative medicine, particularly in developmental disorders and tissue regeneration.

This study found that somatosensory axons innervating Merkel cells in adult mouse skin exhibit significant plasticity, influenced by epithelial and neural factors, indicating a complex interaction in maintaining homeostasis.

This study in adult mice found that somatosensory axons innervating Merkel cells in the skin are highly plastic, with significant remodeling in response to epithelial turnover, and that Merkel cells play a role in limiting axonal branching and promoting their maturation.
