Keratin patterns in hair follicles help understand hair growth and potential hair and nail disorders.

This study found that keratin 6hf, a type II keratin, is expressed in specific regions of mouse and human hair and suggests potential interactions with keratin 17, impacting hair development and associated disorders.

This study found that hair follicle-specific keratins can form different structural assemblies depending on ionic conditions, with hair cortex keratins requiring physiological salt conditions to form intermediate filaments.

This study demonstrates a varied distribution of keratins in the epidermis of the Malayan pangolin, suggesting evolutionary adaptations related to their distinctive scales.

In this study, the combination of keratin-gelatin from poultry feathers promoted early acceptance and viability of full-thickness skin mesh grafts in experimental dogs compared to other treatments.

This study found that K15 is variably expressed in sheep and mouse hair follicles, with specific patterns suggesting a role in the early stages of keratinocyte differentiation.

Junctional proteins stabilize the inner root sheath and connect the companion layer in human hair.

This study identified the expression sites of five KAP5 genes on human chromosome 11q13.5 in scalp skin sections but did not explore their detailed distribution within hair follicles.

This study characterized a new human keratin, hK6irs1, specifically found in the inner root sheath of hair follicles, which suggests its role in the structural integrity and guidance of growing hair shafts.

This study reports the cloning and expression details of two new human type II keratins, K6irs3 and K6irs4, in the hair follicle's inner root sheath, suggesting a distinct functional role related to hair structure.

This study observed that the expression of certain keratins during human epidermal development marks the tissue's commitment to stratification and keratinization processes.

This study found that the tetracycline-regulated transcription system effectively controls conditional gene expression in the mouse epidermis, allowing suppression and activation of specific genes with doxycycline.

This study found that keratin K14 expression occurs early in epidermal cell differentiation, while a hair-specific keratin is expressed later in hair matrix cells, suggesting developmental divergence between the two cell types.

This study found that a keratin mutation may cause diffuse partial woolly hair associated with loose anagen hair syndrome in some families, but other genetic factors could play a role in different cases.

This study demonstrated that hair follicle bulge stem cells can form epidermis in a tissue-engineered skin model, highlighting the significance of K5/K17 filaments in slow-cycling stem cell subsets.

This study identified the distribution of keratin-associated proteins during cornification in the epidermis of reptiles, revealing unique structural characteristics in sauropsid keratin proteins compared to other vertebrates.

This study found that the fungus Microsporum gypseum enzymatically degrades keratin in human hair, with the sequence of degradation reflecting the keratinization and cystine content of individual hair components in vitro.

This study reports that eccrine sweat glands in mice predominantly develop on the footpads, offering a reference for skin research involving genetically engineered mice.

This study found that keratin derivatives with functionalized thiol groups improved binding to both natural and bleached hair fibers, suggesting a promising strategy for enhancing keratin's durability in hair repair.

This study found that genes in the human keratin-associated protein 1 family may have evolved mainly through gene duplication of cysteine-repeat motifs.

This study found that MAP-2 is intensely expressed in the companion layer of the hair follicle, suggesting its potential importance to follicle integrity and possible involvement in some types of alopecia.

This study found that keratin-associated proteins form part of the developing exocuticle and a-layer in hair fiber cuticle cells, while cornified envelope proteins were absent.

This study found that CMAD wool keratin may protect human hair from damage during repeated bleaching and permanent waving treatments.

This study reported that a Megsin-Cre transgene enables genetic manipulation primarily in skin, forestomach, and esophagus tissues, offering a new tool for studying development and diseases in these areas.

The study observed increased melanin and signs of skin aging in melasma-afflicted skin, with strong CK10 expression in the upper basal epidermis, potentially linked to excessive epidermal cell differentiation and aging.

This study found that both epithelial and hair keratins are expressed in beard hair medulla cells, exhibiting unique patterns and interactions distinct from other hair follicle and epithelial cells.

This study found that wound healing after CO(2) laser resurfacing is faster with occlusive dressings, as they enhance cell migration from hair follicles, compared to untreated skin, which showed delayed re-epithelialization.

This study found that ruby laser hair removal causes microscopic epidermal damage but does not lead to cellular hyperproliferation, unlike ultraviolet-irradiated cell damage.

This study localized Merkel cells in human skin, finding them in the basal layer of glabrous skin at palms and soles, and in the interfollicular epidermis and isthmus region of hair follicles.
