This study found that cortexolone 17α-propionate showed strong topical antiandrogenic activity, outperforming progesterone and several known antiandrogens, but lacked systemic antiandrogenic effects in animal models.

This report presents the first known case of a proliferating hybrid cyst containing both epidermoid and trichilemmal components on the scrotum of a 44-year-old man.

This study found that human hair cuticle and cortex have different protein structures, with beta-sheet and disorder configurations in the cuticle and alpha-helical structures in the cortex.

This study found that in early retinal neurogenesis in mice, the transcription factor Lhx2 regulates Sonic Hedgehog signaling by controlling expression of pathway genes like the co-receptors Gas1 and Cdon.

This study found that hair follicle patterning in development may arise from a combination of epidermal prepattern signals and mesenchymal self-organisation, with fibroblast growth factor and bone morphogenetic protein activities playing key roles.

This study reports that trichocyte intermediate filaments from rat vibrissae and human hair follicles may contain a hollow region at their core, suggesting unique structural properties.

This report describes a rare case of ectopic adrenocorticotropic hormone syndrome caused by a pheochromocytoma that unusually co-expresses both ACTH and corticotropin-releasing hormone.

This study examines the structure of the "sinuskissen" in cat hair follicles, revealing it as a loose connective tissue susceptible to changes in aqueous flow, and describes its variable three-dimensional shapes.

This study demonstrated that plucked human hair follicles cultured in a collagen gel matrix developed spike-like structures, suggesting a useful method to study outer root sheath cell growth and differentiation in vitro.

This study reports new cellular features and complex interaction systems in fiber differentiation, indicating more intricate cellular organization than previously recognized, including features like mast cells and primary cilia.

The document describes a method for preparing hair for microscopy by embedding it in plastic, cutting it, and storing it cold before imaging.

This review synthesizes existing research on eyelid pilomatrixomas, highlighting the challenges in diagnosis and the importance of understanding their presentation and management strategies.

This report describes an unusual case of proliferating trichilemmal cyst with trichoepitheliomatous change in a young woman, differing from its typical presentation in elderly women.

This study suggests that PrPC plays a role in the differentiation of mouse embryonic stem cells during neurogenesis, impacting neural progenitor cell development.

This study suggests that pilomatrixomas' maturation towards areas of shadow cells is linked to a gradual loss of differentiation-specific hair keratins, supporting a hair matrix origin for the tumor.

In this study, researchers mapped gene expression in developing hair follicles to reveal unknown cell populations and markers, suggesting early establishment of cell fates in hair placodes.

This study revealed the complex three-dimensional innervation of touch domes in cat forepaw skin, highlighting the extensive branching and unmyelinated endings associated with Merkel cell–axon complexes.

This study found that dermal papilla cells in culture may enhance and attract follicular epithelial cell growth, suggesting their pivotal role in hair and follicle development.

This case report described a facial hairline tumor initially diagnosed as a sebaceous cyst but ultimately confirmed as a rare Proliferating Pilar Tumor with focal malignancies upon histopathological examination.

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 phase 1 study reported that after administering supratherapeutic doses of cortexolone 17α‐propionate, a topical antiandrogen intended for hair loss treatment, there was no effect on the QTc interval, indicating no measurable cardiac safety concerns in the concentration range tested.

This research suggests that both proposed pathways into hair fibers for molecule penetration are valid and complementary, with all fiber structures acting as potential routes for delivering materials.

This study revisits and reproduces Felix Pinkus' concept of the vitreous membrane in hair follicles, suggesting these structures may play a role in differentiation or nutrition due to their location in metabolically dynamic regions.

This study found that local refinement of hair follicles into higher order patterns can occur without the core planar cell polarity system, but global alignment with body axes requires its function throughout development and regeneration.

This case report describes a hybrid cyst in a Sprague-Dawley rat, showing both infundibular and matrical differentiation similar to different parts of normal hair follicles.

In this study, researchers found that the cornification process in the nuptial pads of Xenopus frogs involves the expression of the type II hair keratin homolog, krt59, and is regulated by the transcription factor hoxc13, showing similarities to mammalian hair evolution.

In this study, researchers developed a detailed spatial atlas of healthy human skin and basal cell carcinoma, revealing that basal cell carcinoma likely originates from hair follicles and involves expansion of specific fibroblast subpopulations found in healthy skin.
