This review discusses the use of natural products in cosmetic preparations for skin and hair care, but reports no new research results.

This study developed molecular signatures for dermal papilla cells and their niche, uncovering novel signaling regulators and genes linked to hair disorders, which may inform future hair development research.

This review discusses the role of DHEA in intracrinology, highlighting its impact on breast and prostate cancer treatment and potential as a menopause therapy, but reports no new research findings.

This study found that Shh from neurons signals to Gli1-expressing cells in the hair follicle, cultivating a niche where these bulge cells can potentially transform into epidermal stem cells in wound healing.

This review discusses the brain-skin connection, the skin's role in stress response, and highlights unmet challenges in understanding stress-induced skin inflammation but reports no new experimental findings.

This study found that, in mouse tail epidermis, stem cells rapidly activate and regenerate new progenitors to repair wounds, with mechanisms affecting their proliferation, differentiation, and migration.

This review discusses the crosstalk between auxin and ethylene in seedling growth and development, emphasizing how ethylene modulates auxin's effects across different tissues.

Basal cell carcinoma mostly starts from cells in the upper skin layers, not hair follicle stem cells.

This study found that while genetic ancestry affects physical appearance traits in Latin American populations, it accounts for only a modest portion of the observed variation.

This review discusses experimental data, technologies, and genetic factors related to stem cell niches, highlighting their role in tissue regeneration and diseases, but reports no new results.

This study suggests that skin-derived precursors from Sox2(+) hair follicle dermal cells have the potential to function as dermal stem cells, supporting hair morphogenesis, dermal maintenance, and wound-healing.

This review discusses the role of Lgr5 as a marker for identifying adult stem cells, particularly in the intestine and hair follicles, and reports no clinical results.

This study found that super-enhancers are essential for hair follicle stem cell identity, lineage commitment, and plasticity in mice, with SOX9 being a key regulator of these chromatin dynamics.

This study found that using a standardized protocol with microspheres of approximately 1.5 micrometers enhances penetration into hair follicles, particularly when skin is treated with cyanoacrylate skin surface stripping.

This study found that in mice, inactivating beta-catenin in the dermal papilla reduces hair follicle progenitor proliferation and disrupts the hair cycle.

This review discusses the protective roles of skin-resident immune cells in maintaining tissue homeostasis and facilitating wound healing, but reports no new experimental findings.

In this study, researchers found that wound healing in mouse skin recruits diverse fibroblasts, including myeloid-derived cells, which contribute to regenerating adipocytes.

Ets2 gene is crucial for placental development in mice.

This review discusses the role of the TOR pathway in aging and suggests that rapamycin could potentially target age-related diseases, but reports no new clinical results.

This study identified Lgr5 and Lgr6 as receptors expressed by small populations of stem cells in various adult organs, with Lgr5+ve cells forming long-lived organoids in certain mouse models.

This study found that rat whisker follicle stem cells can be expanded in culture and transplanted to form functional hair follicles, demonstrating their multipotency and potential for regenerative medicine.

The skin's layers protect, sense, and regulate the body's internal balance, but can be prone to cancer.

In this study, homozygous VDR null mutant mice exhibited nonfunctional vitamin D receptors, leading to growth abnormalities and revealing the limited physiological importance of vitamin D pathways outside the classical receptor.

This review discusses the limitations of animal models, particularly mice, in accurately predicting human skin wound healing outcomes and emphasizes understanding species-specific differences in skin characteristics for better translation to clinical settings.

This study identified new dietary ligands for the human vitamin D receptor, including curcumin and gamma-tocotrienol, which may influence its biological functions.

This study reveals that overexpression of Wnt3 in transgenic mouse skin leads to a short-hair phenotype and cyclical balding due to structural defects in hair shafts, highlighting a role for WNT signaling in hair growth regulation.

This study found multipotent progenitors in sweat ducts that become unipotent after sweat gland development, highlighting distinct regenerative capabilities in adult glandular skin stem cell populations.

This study identifies mutations in the SRD5A3 gene as a cause of a new type of congenital disorder of glycosylation, impacting mental, ophthalmologic, and cerebellar functions.

This review discusses the role of stem cell progeny as integral components of stem cell niches, offering feedback that may influence different stem cell systems' microenvironments, but it presents no new research findings.

This review discusses the preclinical and clinical data on teriflunomide for multiple sclerosis, highlighting its selective action on immune cells without causing clinical immune suppression, and provides no new clinical results.
