This review discusses the mechanisms and potential benefits of platelet-rich plasma therapy for various skin conditions and reports no new clinical findings.

This review discusses the complex correlation between cellular senescence and PCOS, emphasizing senescence markers, mechanisms, and potential anti-senescence therapies, but reports no new clinical results.

This study found that stem cells can temporarily act as non-professional phagocytes during hair cycle regeneration by clearing apoptotic cells through a process requiring local lipids and retinoids for activation, providing insights into their dual role in maintaining tissue integrity.

This review discusses the unique features of fetal wound healing that may enable scarless repair and reports no new experimental findings.

This study found that both PHDPE and ePTFE hair-bearing scaffolds were well tolerated in a rat model, with minimal infection or extrusion, though artificial hair showed progressive loss over time.

This review discusses the processes of melanocyte stem cell quiescence and activation, focusing on their interaction with hair follicle stem cells, and highlights current research on hair graying mechanisms; it reports no new results.

In this study, BTP-loaded solid lipid nanoparticles were developed and shown to protect hair from heat-induced damage by enhancing cuticle integrity and thermal resistance in simulated thermal straightening conditions.

This study identified increased expression of ACAA1 and its regulation by hsa-miR-1343-3p, linking androgenetic alopecia to lipid metabolism pathways, particularly through PPAR signaling, in scalp tissues.

In this study on mice, elevated IGF-1 levels in the skin were linked to premature aging of hair follicles, but interventions like reducing IGF-1 or using senolytic treatments helped restore stem cell health and counteract aging effects.

This review highlights the multifunctional role of exosomes in dermatology, noting their potential as therapeutic agents for conditions like skin cancers and hair disorders, while also indicating pathogens exploit them for immune evasion.

In this study, oral spermidine supplementation was found to significantly prolong the hair follicle anagen phase and reduce hair loss, with effects persisting three months after treatment in healthy participants, suggesting potential therapeutic benefits for hair loss conditions.

This review explores the current and experimental therapies for chronic wounds, emphasizing the potential of cellular and immunotherapies in addressing these persistent conditions, but notes a shortage of comprehensive studies on their effectiveness.

3D-oxy exosomes may significantly boost hair growth, offering new treatment options for hair loss.

This study found that gene therapy using a mouse cytomegalovirus vector with telomerase reverse transcriptase or follistatin significantly extended lifespan and improved health markers in mice, without adverse effects.

This review outlines the various fibroblast subsets in the skin dermis, their origins, and their influence on epidermal stem cell behavior, highlighting the role of the local dermal niche in stem cell plasticity.

This study found that claudins CLDN1 and CLDN3 are crucial for maintaining proper hair follicle structure in mice, and their dysregulation may lead to telogen hair loss.

This study found that age-related changes in scalp dermal fibroblasts, including increased MMP-1 and reduced ECM components, may significantly affect the hair follicle environment and contribute to hair aging.

The authors concluded that low energy laser therapy may serve as a useful complementary treatment for skin diseases such as lichen planus, infectious finger pulpits, scalp alopecia, and crural ulcers.

This review explores recent insights into the diverse cell populations involved in skin development, homeostasis, wound healing, and cancer progression but reports no new results.

This study proposes the miR-22-5p-LEF1 axis as a novel pathway that may regulate hair follicle stem cell proliferation.

This review discusses emerging treatments and mechanisms for alopecia, highlighting potential therapies like janus kinase inhibitors and advances in stem-cell technology, but reports no new experimental results.

In this study, researchers investigated the penetration and cellular responses to nanoplastics in human skin models with compromised barriers, finding that nanoplastics can penetrate the skin, accumulate in cells, and trigger inflammatory responses through specific signaling pathways.

This study found that an inter-hair-follicle blood vessel network, originating from ND-GFP-expressing stem cells, contributes to angiogenesis in skin transplants and wound healing in ND-GFP transgenic mice.

This study provided the first proteome dataset for alopecia areata, revealing novel pathways in the disease mechanisms that may lead to new therapeutic targets.

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 in SPF lambs found that primary and secondary orf virus infections trigger similar skin responses, but the primary infection caused a more severe and prolonged reaction.

This study suggests that epigallocatechin gallate (EGCG) from green tea may counteract DHT-induced hair follicle damage by modifying the miRNA expression profile in human dermal papilla cells.

In this study, researchers developed a simple, non-invasive method to monitor circadian gene expression using whole hair root cultures, finding that elderly dementia patients' peripheral clocks still oscillate similarly to younger, healthier individuals, which suggests cellular senescence minimally affects some aspects of circadian rhythms.

This study found that incorporating hair follicle-primed spheroids into skin constructs showed potential for developing hair-bearing skin mimetics with follicle-forming abilities in vitro.
