This study found that elevated STAT5 levels are linked to improved hair-inducing capabilities in human dermal papilla cells, and reducing STAT5 impairs hair follicle induction.

This study found that treating human dermal fibroblast cells with ginsenoside Rd increased the expression of mRNA associated with the dermal-epidermal junction, suggesting potential as an anti-aging cosmetic ingredient.

This study found that TGFbeta is a key pathway causing age-related loss of dermal fat's antimicrobial function, suggesting that targeting TGFBR might help restore skin defense against infections in older age.

This chapter reviews the presence and roles of stem cells in various body systems, focusing on their lifelong function in animals and humans, and reports no new experimental findings.

This review discusses three aspects of cell fate specification across Metazoa and reports no new experimental results, highlighting the formation of nematode equivalence groups, evolution of echinoderm skeletogenic mesoderm, and adult cell fate regulation.

This research found that keratin hydrogels derived from human hair may support cell viability and proliferation, indicating potential as 2D and 3D soft tissue culture scaffolds.

This symposium abstract reports no new experimental results and discusses the pathophysiology of hair growth as presented at an event organized by the Institute of Dermatology.

This study found that the absence of Hes1 in hair follicles delays secondary hair germ activation and shortens the anagen phase, impacting HFSC self-renewal and long-term hair regeneration.

This study found that αvβ6 integrin inhibits keratinocyte proliferation during wound healing and hair regeneration, suggesting its downregulation may enhance recovery and influence epidermal stem cell behavior.

This review discusses the increased use of platelet-rich plasma in dermatology for conditions like skin ulcers and alopecia but reports no new clinical results, emphasizing the need for more scientific evidence to support its benefits.

In this review, retinoids are highlighted as promising agents for promoting scarless skin regeneration by coordinating cellular and molecular processes that suppress fibrosis, enhance re-epithelialization, promote angiogenesis, and enable hair follicle formation, potentially advancing functional skin repair.

This study found that two microRNAs, oar-miR-23b and oar-miR-133, inhibit the development of hair follicles in superfine wool sheep by targeting genes involved in key signaling pathways, suggesting their potential use as molecular markers for breeding fine wool sheep.

This study found that a high-fat diet in macaques led to severe gastrointestinal inflammation and chronic wasting, with more pronounced effects in females, highlighting the potential risks of certain dietary interventions in obesity models.

This review discusses the fundamental hallmarks of aging as they relate to skin aging and highlights the prominent roles of oxidative damage and the extracellular matrix in photoaging, reporting no new results.

This study established a rat model of radiation-induced dermatitis using 90 Gy irradiation, which may aid in exploring new treatments and understanding the pathology, particularly highlighting autophagy regulation as a potential therapeutic target.

This review discusses recent genetic approaches to understanding tissue regeneration mechanisms in vertebrates and reports no new results; it highlights objectives in identifying cellular and molecular factors involved.

This study found that thymosin β4 is highly expressed in multiple human tissues and may play a role in organ function and angiogenesis through co-localization with VEGF.

This study observed that cultured dermal papilla cells showed distinct functional properties from dermal fibroblasts, including lower proliferation rates, higher adhesion to collagen type IV, and different cell-matrix interactions.

This study found that in skin blister healing, hair follicle development is compromised as stem cells repair wounds at the expense of morphogenesis gene expression.

This study found that knocking out the integrin β1 subunit in induced pluripotent stem cells enhanced their migration and improved their wound-healing effects in a mouse model.

This study found that subcutaneous adipose tissue-derived extracellular vesicles (AT-EVs) protect skin from photodamage by enhancing fibroblast proliferation and reducing oxidative stress compared to those from adipose-derived stem cells.

This study reviewed recent literature and reported that although PRP products are recognized for benefits in dermatology, including wound care and hair growth, there remains a need for standardized protocols and consensus to enhance their acceptance in cosmetic dermatology.

Fibronectin is essential for hair follicle regeneration and may help rejuvenate aged skin.

This study found that alpha-tocopherol acetate did not demonstrate any protective effect against hair loss induced by doxorubicin in patients with solid tumors.

This study demonstrated that hyaluronan gel is a promising biomaterial for 3-D in vitro culture of mouse ovarian follicles, supporting the production of fertilizable metaphase II oocytes.

This review discusses the potential of platelet-rich plasma applications in regenerative medicine and explores recent progress and challenges in translating non-clinical PRP findings into human treatments, but reports no new clinical results.

This review discusses the development, lineages, functions, and roles of fibroblasts in fibrosis across four organs, highlighting their capabilities in tissue repair and contributions to fibrotic disorders when aberrantly activated, but it reports no new experimental findings.

This study found that a biomaterial gel made from human hair keratins facilitated nerve regeneration in an animal model, potentially matching the effectiveness of traditional autografts.
