Congenital Adrenal Hyperplasia is mainly caused by enzyme deficiencies, leading to varying symptoms like hormone imbalances and physical changes.

This study developed immortalized cell-based models to screen and evaluate potential hair-care materials by forming hair follicle-like structures that respond to hair growth-promoting compounds.

This study in Hexi cashmere goats found that secondary follicle activity increases with time, and Hoxc13 expression varies significantly across different growth stages, suggesting a role in follicle activity.

This study found that HIF-P4H-2 function in FoxD1-lineage cells is crucial for normal hair follicle development and homeostasis in mice, implicating disrupted HIF, TGF-β, and Notch signaling pathways in associated defects.

This study found that high-speed optical coherence tomography may be a promising non-invasive tool for analyzing human hair conditions.

In this study, researchers observed that testicular 17β-hydroxysteroid dehydrogenase deficiency in an inbred Arab population in Israel leads to genital ambiguity at birth and progressive virilization after puberty.

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.

Hair follicle stem cells can become heart muscle cells.

In this study, Fgf20 was found to trigger movement and morphogenesis in dermal fibroblasts, facilitating dermal condensate formation essential for hair follicle development.

In this study, ultradeformable liposomes containing Tween 20 or terpenes increased phospholipid bilayer fluidity and enhanced skin penetration of sodium fluorescein, with terpenes improving hair follicle penetration.

According to this study, human scalp hair follicles containing pluripotent stem cells demonstrated the ability to differentiate into cardiac muscle cells and other cell types, suggesting potential applications in heart and nerve regeneration.

This article reviews the significance of hair in human social and sexual communication, reflecting on the interest in hair cosmetics and the demand for medical advice on hair issues, and reports no new research findings.

This study found that while extracellular matrix components like hyaluronic acid promoted larger organoid formation, other matrix components hindered hair follicle germ assembly in an in vitro model.

This study found that concentrations of haloperidol and its metabolite in human scalp hair significantly correlated with the daily dose and plasma trough levels in patients taking haloperidol.

This workshop overview concluded that follicular epithelial stem cells are multipotent and located in the bulge region of hair follicles, contributing to hair, epidermis, and sebaceous gland formation.

This article discusses the bi-compartmental organization of hair follicle stem cell niches for balancing stem cell cycling and organ growth and proposes similar structures may exist in other adult stem cell niches but reports no new experimental results.

This study found that loliolide enhanced hair growth-related functions in 3D dermal papilla spheroids by activating AKT/β-catenin signaling pathways, with increased expression of related growth factors and genes.

In this study, researchers identified at least four distinct basal stem cell populations in the human interfollicular epidermis, each crucial for maintaining epidermal communication and homeostasis.

This study found that biodegradable hyperbranched polyesters improved the solubility and loading capacity of hydrophobic drugs, with complete pyrene release achieved in 16 days under enzymatic conditions.

This study demonstrated that hiPSC-derived hair-bearing skin organoids lacked sufficient type VII collagen at the epidermal-dermal junction, indicating a need for further maturation to model certain forms of epidermolysis bullosa effectively.

This review discusses the distinct roles and surprising developmental flexibility of multiple somatic stem cell types in tissue maintenance and repair, reporting no new results but highlighting emerging questions about their regulation and origins.

This study found that 1,2,3,4-tetrahydroquinoline derivatives, particularly N-methyl-7-amino-1,2,3,4-tetrahydroquinoline, may be excellent blue dye candidates for human hair, offering superior color purity, stability, and fastness compared to 2,3-dihydroindoles.

This issue information abstract introduces a collection of articles, including one on hair keratins' unique filament formation, without reporting new experimental findings itself.

hHb1, hHb3, and hHb6 mRNAs start expressing at the same time in hair follicles.

This review discusses how using hydrogels as a three-dimensional culture platform for mesenchymal stem cells might affect the production of extracellular vesicles, highlighting challenges in standardization and opportunities to boost EV yield via combined hydrogels and bioreactor methods.

This study found that incorporating cell-adhesive ligands into 3D peptide hydrogels supports the survival and osteogenic differentiation of human amniotic mesenchymal stem cells.

In this study, researchers using the hair paradigm highlighted how periodic patterning and compartmentalization enable diverse regenerative behaviors, including region-specific renewal cycles and emergent properties like regenerative waves in organ populations.
