This study suggests that pilomatricoma can differentiate towards various hair follicle structures, including hair matrix, hair cortex, follicular infundibulum, outer root sheath, and hair bulge.

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.

This study found that hydrogenated palm oil effectively conditions damaged hair by preventing water-induced swelling, with TOF-SIMS analysis showing that its component tripalmitin penetrates the hair's cuticle and outer cortex.

This study observed that calcifying epithelioma of Malherbe is composed of tumor cells that differentiate into both hair cortex and outer root sheath, supporting its hair follicle origin.

This study observed that in mouse hair follicles, enzymes Aldh1a2 and Aldh1a3 have distinct expression patterns that suggest they are involved in different signaling pathways during the hair cycle.

This study found that in androgenetic alopecia patients, there is enhanced expression of type 2 TGF-β and type II receptors in hair follicles, suggesting a link to hair growth cycle changes.

This study found that increased expression of type 2 TGF-β and type II receptor was observed in the bald vertex area of hair follicles from androgenetic alopecia patients, suggesting a role in catagen induction.

In this study, researchers found that the curliness of human hair is associated with an asymmetric structure at the cellular level, particularly in the differentiation of the precortex.

This study investigated the immunohistochemical characteristics of keratin proteins in epidermal appendages, finding variable staining patterns in different skin structures and tumor cells, which suggests differences in keratinization.

This study identified a unique concentric double-layered structure in both Japanese and Caucasian SHINAYAKA hair, associated with improved flexibility and elasticity, and developed a succinic acid treatment to enhance these properties.

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 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 investigated the role of NLRP3 inflammasomes in alopecia areata and found that outer root sheath cells may contribute to inflammation by increasing IL-1β and HMGB1 secretion when stimulated with double-stranded RNA.

BTNL2 helps protect hair follicles from immune attacks.

This study found that stabilizing HIF1A in hair follicle cells promoted a shift to glycolysis, potentially reducing oxidative stress and promoting hair growth, particularly in balding dermal papilla cells.

This study found that trichoblastomas and nodular basal cell carcinomas have similar cytokeratin expression patterns, indicating differentiation towards the outer root sheath epithelium.

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 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 observed that PAD type III and trichohyalin are expressed earlier than their deiminated form during the first and second hair cycles in rat hair follicles, indicating a potential additional factor is involved in triggering deimination.

This study found that injected wax did not prevent androgenic alopecia and led to remodeling of the skull's outer cortex over a 30-year follow-up, necessitating removal due to a fibroxanthoma.

This study found that repeated cycles of wetting and blow-drying hair fibers can cause cracks in the hair cuticles, particularly among individuals who frequently blow-dry their hair.

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

Mutations in keratin genes may link hair disorders to dental decay.

In this study, researchers found that the morphology, composition, and elemental enrichment of domestic cat hairs vary significantly along their length, contributing to a functional gradient that affects mechanical properties and challenging assumptions of uniformity in hair structure.

This study found that both transgender and cisgender individuals experience similar psychological and cosmetic benefits from surgical body modifications, but cisgender individuals typically have more autonomy and support in pursuing these surgeries.

This article reviews the types and characteristics of adrenal cortex tumors, including their hormone secretion and detection as incidental findings, but presents no new research results.

This review discusses the cell biological characteristics of the outer root sheath of normal human hair follicles and highlights some similarities and differences with trichilemmal tumors, but reports no new results.

This study observed that the molecular structure of keratins in hair fibres' discrete transition zone differs in breast cancer patients, with altered lipid ester absorption bands reverting post-cancer removal.

Minoxidil works in liver and outer hair root sheath for hair growth.

This study proposed the existence of a membrane-like structure between the cuticle and cortex in human hair, which may provide strong protection against external stimuli.
