This study reports two cases of trichoblastic neoplasms with histologic features suggesting they may be distinct, locally aggressive trichoblastic carcinomas separate from basal cell carcinoma.

This case study reports a peculiar variant of an epidermal cyst in a patient, featuring unique characteristics like brownish, lumpy contents resembling bone marrow.

In this study, hair shafts from trichothiodystrophy patients with ERCC2 mutations revealed abnormal cuticle structures and protein imbalances compared to normal hair shafts.

This study found that distinct glycoconjugate expression patterns in human hair follicle cells suggest complex carbohydrate metabolism, revealing a unique sugar moiety in outer root sheath cells not present in other keratinocytes.

In this case study, a 51-year-old Japanese man was diagnosed with desmoplastic trichoepithelioma after histological examination of surgically excised facial plaques.

This study demonstrated that keratin is widely present in various epithelial cells, providing structural strength and potential insights into the origin of cell lines.

This study shows that microdiffraction experiments reveal structural layers in keratinous tissues, each with different keratin types, potentially explaining their dual role as mechanical support and chemical barriers.

This study found that telocytes in human scalp tissue were located around hair follicles and glands and may be involved in skin regeneration and homeostasis.

In this study, researchers found that serum granulysin levels might serve as a novel marker for disease activity in acute alopecia areata, being significantly associated with broader bald skin areas, poorer prognosis, and co-existing allergic disorders.

This review discusses the various trichoscopic features of androgenetic alopecia and alopecia areata, noting white dots in advanced cases as indicators of poor prognosis, but reports no new clinical results.

This study found that epithelial components of calcifying epithelioma of Malherbe showed lectin binding and keratin staining patterns similar to normal hair follicles, with prominent Con A staining in tumor giant cells.

This case report details the immunohistochemical study of cytokeratins in a trichofolliculoma, providing insights but no new clinical findings.

This research found that a monoclonal antibody (MAb 17) specifically reacts with certain subunits of trichocyte keratin in rats, and discovered that trichocyte keratin expression in hair and whiskers begins at different embryonic stages.

This study identified a new type II cytokeratin, named K6hf, exclusively expressed in the companion layer of the human hair follicle, distinguishing it from other keratins and suggesting a unique biochemical role.

This study found that mu-crystallin gene expression in mouse skin is highest during the anagen phase of hair development, suggesting its possible role in hair follicle growth.

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

This study found that cultured hair apparatus cells initially showed low keratin antibody reactivity, which increased by day 6 as cells differentiated and corresponded with electron microscopic observations.

This study suggests that human hair follicle cells and epidermal keratinocytes differ in their degree of keratinization and other characteristics when cultured on mixed collagen membranes.

This study observed that multinucleate giant cells were present in 31% of biopsy specimens from patients with male pattern alopecia but not in other alopecia types, suggesting a potential histologic marker for androgenetic alopecia.

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 suggests that the mechanical robustness of hair may be enhanced by the binding interactions of keratin-associated proteins, particularly KAP8.1, with intermediate filament proteins.

This study suggests that the cell membrane complex in hair cuticles contains hydrophilic regions with disulfide bonds allowing polymer uptake and hydrophobic lamella-like lipid layers.

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.

In this study, the researchers identified LHX2 as a specific marker for hair follicle placodes, differentiating them from eccrine sweat gland placodes through double immunofluorescence staining.

This study discovered that the lipid in human hair follicles is mainly located in the hair cuticle and keratinized inner root sheath, distinct from sebaceous and epidermal lipids, suggesting a potential role as a "hair barrier.

This study found that dermal papilla and dermal sheath cells from human scalp tissue differ from interstitial dermal fibroblasts in morphology and produce varying levels of TGF-beta 2.

This study presents recombinant human hair keratins K31 and K81, observing novel nanostructures from their self-assembly and emphasizing disulfide crosslinking's role in this process.

Aδ-LTMRs have complex synapses with glycine, while Aβ-LTMRs have simpler ones.
