Fibroblasts can be turned into melanocytes for potential skin treatments.

Hedgehog signaling helps keep hair follicle stem cells the same in both young and old human skin.

This study observed that in aged mouse skin, there was an increase in IL-17-expressing T helper cells, γδ T cells, and innate lymphoid cells, and blocking IL-17 signaling reduced skin inflammation and delayed age-related changes, suggesting it as a potential target to mitigate skin aging.

This article details laboratory methods for isolating and culturing human dermal papilla cells but provides no new experimental results.

This study found that FOXN1 haploinsufficiency is a significant genetic factor causing T cell lymphopenia at birth, linked to reduced thymic function in both humans and mice.

This study found that skin microbiota, particularly in wild-type mice, promotes wound-induced hair follicle neogenesis and wound healing, highlighting the potential downsides of routine antibiotic use on skin regeneration.

This study found that micro-needling with cosmeceuticals or platelet-rich plasma significantly improved wrinkles, skin laxity, scar softening, and hair growth over 12 months, with minimal side effects, and that the best results occur with pigment and platelet massaging between 5 to 30 minutes post-treatment.

This study found that JunB, a transcription factor, is crucial for maintaining epidermal-pilosebaceous stem cell homeostasis by regulating progenitor cell behavior and preventing sebaceous gland dysfunction.

Keratin peptides can change hair shape gently without harsh chemicals.

In this study, patients receiving adipose-derived stromal vascular cell transplantation for alopecia areata experienced significant hair regeneration, increased growth, and improved hair quality after 3 and 6 months, indicating potential efficacy of this stem cell-based therapy for hair loss.

This study found that lymphatic vessels in mice are important for hair follicle development and organization, as their depletion blocks hair growth.

This mini-review discusses human hair follicle development and summarizes genetic disorders linked to abnormalities in hair follicle morphogenesis, structure, or regeneration, but reports no new experimental results.

In this study, socially defeated mice showed increased alcohol consumption, and CRF-R1 antagonism selectively reduced drinking in these mice, suggesting a potential treatment target for stress-related alcohol use disorders.

This study found that inhaled fluticasone for 11 months did not adversely affect the immune function or response to vaccination in horses with heaves.

This article reviews the complexity and diverse manifestations of systemic lupus erythematosus, highlighting potential genetic, hormonal, and environmental factors in its pathogenesis without presenting new clinical findings.

This review found that three monthly PRP injections improved hair density in patients with androgenetic alopecia compared to placebo, but more rigorous studies are needed for broader dermatological applications.

This study found that in adult mouse skin, reduced levels of histone H3 K4/K9/K27me3 during hair follicle stem cell quiescence are linked to proper tissue homeostasis.

This study demonstrates that incorporating human neopapilla into reconstructed human skin can initiate hair follicle morphogenesis by stimulating epidermal invagination and maintaining follicle-inductive properties in vitro.

This study reports that a sarcoptic mange outbreak, likely originating from mange-infected llamas from a governmental program, dramatically reduced vicuña and guanaco populations in San Guillermo National Park, Argentina.

This article reviews skin disorders in Parkinson's disease, highlighting the potential of skin studies and stem cell research to advance understanding and treatment of the neurodegenerative disorder, without presenting new results.

This review discusses major advances in understanding inherited hair diseases through genetic research and reports no new clinical results; the authors emphasize the potential for new preventive and therapeutic tools.

This study found that using ectopic expression of CD24 is a promising approach for selecting genetically modified human epidermal stem cells for safe cutaneous gene therapy in cancer-prone conditions.

This article reviews the role of R-spondins and their receptors in bone development and metabolism, highlighting their potential modulatory effects and clinical implications for treating bone loss diseases, but reports no new clinical results.

This review discusses how certain genetic, infectious, and metabolic conditions might influence disease severity and highlights the potential for new therapies, but it presents no new research findings.

In this study, hair loss in Japanese men with androgenetic alopecia was found to be primarily due to hair follicle miniaturization rather than hair shedding, particularly in those aged 25 and older.

In this study, ustekinumab did not promote hair regrowth in human patients with alopecia areata or prevent disease development in an AA mouse model, suggesting limited efficacy for this treatment.

This study found that 5% primed conditioned medium from human umbilical cord blood-derived mesenchymal stromal cells significantly improved hair density, thickness, and growth rate in patients with androgenetic alopecia.

This study found that melanocyte progenitor cells are present in human subcutaneous adipose tissue and may differentiate into mature melanocytes, suggesting potential applications in treating skin diseases and rejuvenation.

This study identified a regulatory element necessary for Foxn1 expression specifically in mouse thymic epithelial cells, crucial for thymus development but not affecting hair follicles.

This study observed dynamic behaviors such as cluster formation, migration, and active proliferation of transplanted bone marrow cells in a mouse model, providing insight into cellular-level changes post-transplantation.
