This review discusses 46,XY disorders of sex development caused by defects in androgen production and highlights the need for long-term care from experienced multidisciplinary teams, but it reports no new clinical findings.

This review discusses hormonal influences on hair growth and suggests that understanding hormone-gene interactions may improve treatment of hirsutism and alopecia, but reports no new clinical findings.

This review discusses the enhanced understanding of how stem cell niches respond adaptively to systemic signals, aging, and local perturbations, but reports no new research findings.

This review discusses the role of pharmacological sciences in advancing regenerative medicine technologies but reports no new experimental findings; the authors advocate for increased pharmacologist involvement to drive innovations.

This review explores genetic and lifestyle factors influencing hair diversity and reports no new findings, calling attention to the potential for future discoveries in genetic and epigenetic research.

This article reviews the generation of complex integument patterns through genetic, chemical, and environmental influences, with applications in tissue engineering, but reports no new experimental results.

This report reviews current advances in hair follicle regeneration for tissue-engineered skin grafts and highlights the feasibility and challenges of creating human hair follicles in this setting, suggesting key bioengineering requirements.

This review summarizes recent discoveries about how tissue-resident stem cells interact with their environments during normal conditions and after injury, without reporting new results.

This study observed that rat vibrissa hair follicles cultured in vitro showed morphological changes suggesting cyclical activity but remained blocked in the pro-anagen stage.

This study reports that X chromosomes often show greater differentiation between human populations than autosomes, likely due to a mix of demography and selection pressures.

This study found that applying TPA to mice accelerated hair follicle regeneration by activating Akt and Wnt/ß-catenin signaling pathways, involving hair follicle stem cell proliferation.

This study found that BAF200, a subunit of the PBAF chromatin remodeling complex, is crucial for heart development and coronary artery formation in mice, as its absence led to embryonic lethality with severe cardiac defects.

This review discusses recent advances in understanding the Eda pathway's role in developmental biology, and highlights ongoing trials and areas for further research, including Eda's potential involvement in cell processes and disease.

This study identified a large deletion in the desmoglein 4 gene as the genetic basis of the Iffa Credo "hairless" rat's skin phenotype, linking it to lanceolate hair mutations.

This study found that in vitro, cultured bulge cells from human hair follicles possess properties of primitive cells, supporting the hypothesis that hair follicle stem cells reside in the bulge area.

This study developed an in vitro system to analyze human skin progenitor cells' ability to form hair peg-like structures, providing insights for engineering hair follicle organoids.

This review discusses various aspects of hair follicle biology and highlights unresolved questions and potential new research avenues, but presents no new experimental findings.

This article reviews the proposed mechanism of minoxidil in treating androgenetic alopecia, suggesting it may prolong the anagen phase by modulating cell growth factors and vascular activity, but reports no new results.

This review discusses recent advances in the genetic understanding of inherited hair and nail disorders and reports no new clinical results.

This study found that in wound-induced hair neogenesis, African spiny mice and laboratory mice exhibit different morphogenetic field formation patterns related to tissue stiffness, suggesting evolutionary developmental biology advantages.

This study found that ILK deficiency disrupts hair follicle development by impairing cell polarity and laminin-511 assembly, but these defects can be partially reversed with exogenous laminin-511.

This study reports that dynamic interactions between stem cells and their niche, influenced by macro-environmental factors, regulate regenerative behavior in integument pattern formation.

This study observed that human hair follicles with a completely destroyed bulb can regenerate after being grafted onto immunodeficient mice, entering a shortened dystrophic telogen followed by anagen phase.

This study found that the XEDAR receptor can activate the non-canonical NF-kB pathway involving p100 processing, which is regulated by interactions with TRAF proteins and specific kinases.

This study found that feeding mice high levels of dietary vitamin A increased WNT signaling, which activated hair follicle stem cells and may have accelerated alopecia areata progression.

This study found that their system effectively supports the rapid formation of human hair follicle organoids, providing a platform for studying hair regeneration and drug screening.

This review discusses strategies to regenerate human hair follicles using stem cells and reports no new experimental results; the authors note existing challenges and the potential of hiPSCs for future applications.

This review examines the interaction between hedgehog and Wnt/β-catenin signalling in hair follicles and basal cell carcinoma, linking Hh pathway inhibition to both tumor regression and alopecia.
