This study discovered that the circadian clock influences hair follicle regeneration, making hair grow faster in the morning and causing more radiation-induced hair loss in the morning compared to the evening.

This study suggests that miniaturization in pattern hair loss may occur abruptly and can be reversed with treatment, as supported by histologic evidence in finasteride-responsive patients.

Hair color production is closely linked to the active growth phase of hair in mice and may also influence hair growth itself.

This article reviews the current status of oral retinoids in dermatology and reports no new clinical findings.

This study found that PDGFA is critical for the proliferation and maintenance of adipocyte stem cells in skin but not other white adipose tissues, highlighting unique regulatory mechanisms in different tissue depots.

In this study, sequences upstream of the TGM3 gene were found to regulate epithelial-specific gene expression in keratinocytes, suggesting potential applications in gene therapy.

This study found that the vitamin D receptor in lampreys, which lack bones and hair, binds 1,25-dihydroxyvitamin D3 and may function to induce enzymes for detoxifying substances.

This study found that thymus transplantation in infants with FOXN1 deficiency led to T-cell reconstitution and functional immunity, resolving serious infections and cytopenias.

This review discusses advances in protecting against chemotherapy-induced alopecia and reports no new clinical results; calcitriol and cyclosporine A emerged as promising agents in animal models with broader efficacy across multiple chemotherapy drugs.

This review discusses the pharmacological properties and clinical applications of cyproterone acetate and similar antiandrogens, noting previous failures in local applications due to concentration limitations; it reports no new empirical results.

This study describes the first case of female pseudohermaphroditism due to a novel homozygous glucocorticoid receptor gene mutation, indicating possible pre- and postnatal virilization in affected females.

This study found that the transcription factor p63 is crucial for horizontal basal cell differentiation in the olfactory epithelium, suggesting a p63-dependent mechanism activates reserve stem cells after injury.

This study found that low oxygen conditions and ECM degradation products increased the proliferation and migration of perivascular stem cells without altering their phenotype, suggesting potential roles in tissue repair.

In this study, a novel mutation in the glucocorticoid receptor gene was identified in a young woman, impairing glucocorticoid signaling and leading to generalized glucocorticoid resistance.

This chapter reviews the complexity of hair and wool follicle formation, emphasizing the importance of cytological studies to understand the relationship between cellular components.

This review discusses the genetic factors involved in hair follicle morphogenesis and cycling and reports no new clinical results; it emphasizes the role of genes in hereditary hair diseases.

This review discusses androgenetic alopecia and alopecia areata through a systems biology lens, emphasizing the role of multi-omics data integration to explore molecular mechanisms and potential therapeutic strategies, but offers no new clinical results.

This review discusses mammalian models of epimorphic regeneration to define a vertebrate regeneration blastema, concluding that regenerative failure likely stems from cellular responses to the microenvironment after injury, not progenitor cell availability, and calls for targeted modification studies in mammals to advance human regeneration.

This review evaluates existing research on Keratin 15 to assess its validity as a marker for epidermal stem cells, reporting no new results.

This review discusses recent advancements in hair rejuvenation strategies and assesses the potential of herbal drugs as safer alternatives, but reports no new clinical results.

This study describes a simplified method for isolating and cultivating human hair follicle papillae that can be easily executed by new lab personnel.

This study identified changes in transcription factor gene expression across various signaling pathways during inner ear hair cell regeneration in birds, revealing patterns and potential new pathways for future investigation.

This study found that TPA was significantly more effective than mezerein in inducing dark basal keratinocytes in mouse skin, which may be important in early tumor promotion stages.

This review discusses the use of Dermal Papilla cells as in vitro models for studying hair growth modulators, emphasizing their role in aiding the development of new hair treatments, but reports no new clinical results.

This review discusses the properties and therapeutic potentials of beta-sitosterol, highlighting a need for more detailed studies on its mechanisms and long-term effects in humans; it reports no new results.

This study found that Sophora flavescens extract may promote hair growth in mice by inducing earlier hair cycle changes and regulating growth factors in dermal papilla cells.

In this study, researchers found that depleting mtDNA in mice caused skin wrinkles and hair loss but restoring mitochondrial function reversed these effects, highlighting mtDNA's significant role in skin and hair health.

This study found that blue light at a wavelength of 453 nm promoted hair growth ex vivo, potentially through interacting with OPN3 receptors in human hair follicles.

This review discusses melanocyte development, emphasizing the plasticity of melanoblasts and the role of both intrinsic and extracellular signals in their differentiation and migration, with no new clinical results reported.

This review suggests that isotretinoin's effects on severe acne and various cancers may result from apoptosis, which might also explain its adverse effects through genetic variability.
