This article discusses the role of the American Society of Plastic Surgeons in plastic and reconstructive surgery education but presents no new research findings.

Small molecule DMF improves psoriasis and multiple sclerosis, adult skin cells can be made to grow new hair, certain skin cells initiate hair growth, IL-17C controls gut health and can cause skin inflammation, and skin cells produce IL-17 that can lead to psoriasis.

This study found that modulating Wnt signaling can promote new hair follicle regeneration in adult mouse skin wounds, suggesting potential treatment strategies for scarring and alopecia.

This study found that microencapsulated human hair dermal papilla cells successfully induced hair follicle regeneration on the dorsal skin of nude mice, unlike control groups with free cells or empty microcapsules.

This study found that occlusive dressings on mouse wounds eliminated wound-induced hair neogenesis by upregulating mechanotransduction, which promotes fibrosis, and suppressing Wnt signaling involved in regeneration.

This study identified CXXC5 as a key mediator of hair loss induced by PGD2 and DHT via suppression of the Wnt/β-catenin pathway, with implications for potential therapeutic targets.

This study identified that bacterially-induced metabolic changes in keratinocytes enhance skin and hair follicle regeneration, suggesting that modifying skin microbiome interactions may improve wound healing.

This review discusses the mechanisms of wound-induced hair neogenesis and its similarities with embryonic hair follicle development, but reports no new clinical results.

This study found that Wnt3a liposomes can induce hair follicle neogenesis when delivered subcutaneously, demonstrating their potential for regenerative applications.

This study demonstrates that bacteria contribute to hair follicle neogenesis after skin wounding through IL-1R1 signaling in keratinocytes.

This study found that both human and rat dermal papilla spheroids can induce hair follicle neogenesis, but larger spheroids increase inductivity without significantly affecting hair fiber diameter.

This study observed that earlier-passage keratinocyte cultures led to superior hair follicle neogenesis in dermal-epidermal composites grafted onto immunodeficient mice, suggesting their potential utility in studying human hair follicle development.

This study demonstrated that fibrin hydrogels support skin-derived precursors in hair follicle neogenesis in mice, with new hair growth and regeneration of blood vessels and sebaceous glands observed.

This abstract explores the roles of dermal fibroblasts and keratinocytes in hair follicle neogenesis and regeneration but does not present new experimental results; it suggests more study is needed on the dermal sheath.

This review discusses circadian clock regulation in stem cells and its role in processes like neurogenesis, but reports no new results; the authors emphasize its significance in stem cell function across various tissues.

This study found that laboratory and African spiny mice have distinct spatiotemporal patterns in wound-induced hair neogenesis, with the Twist1 pathway playing a central role in epidermal-dermal interactions for hair primordia formation.

This study found that reducing skin bacteria through cage changes or antibiotics decreased wound-induced hair follicle neogenesis and slowed healing, suggesting skin microbiota and IL-1β signaling are important for regeneration.

This study found that RADA-PRG hydrogels enhanced skin-derived precursor cell proliferation and improved hair follicle neogenesis in mice, suggesting potential use as a scaffold material in tissue engineering.

In this study, researchers found that microglia play a crucial role in neurogenesis and brain regeneration in zebrafish by regulating inflammatory signaling, and their absence impairs these processes.

This study found that transfecting hair follicle stem cells with a PEI-DNA complex expressing hTERT stimulated hair growth in rats by inducing follicle neogenesis and promoting the anagen phase.

This comprehensive review suggests that CD44 signaling plays a significant role in post-natal skin wound healing and scar formation, with potential for therapeutic approaches targeting CD44 to shift from fibrotic scarring towards regenerative healing, including wound regeneration and hair neogenesis.

This study found that a newly constructed composite hydrogel dressing, made from silk fibroin, chitosan, and halloysite, promoted hair follicle neogenesis, angiogenesis tissue regeneration, and scar reduction.

In this study, nondermal-derived CD34+ cells from adult peripheral blood were found to enhance wound healing and contribute to hair follicle neogenesis and skin regeneration.

The researchers in this study identified a new subpopulation of dermal fibroblasts in neonatal murine dermis marked by EGFR, which they report contributes to hair follicle regeneration through the promotion of IGF1, potentially aiding in wound-induced hair follicle neogenesis.

This review highlights the potential of nanotechnology for hair follicle regeneration, focusing on strategies such as hair cycle modulation, progenitor cell stimulation, and wound-induced hair neogenesis, while also discussing regulatory challenges that may affect the development of these innovative approaches.

In this animal study, the researchers found that biodegradable extracellular matrix scaffolds accelerated wound healing and enhanced hair follicle neogenesis in mice, suggesting a role for immune systems in tissue regeneration.

This study found that DPP4 inhibition in mice can enhance hair follicle activation and regeneration, suggesting a potential therapeutic strategy for improving hair growth and wound-induced hair follicle neogenesis.

This study found that 4-aminopyridine significantly enhanced skin wound healing by accelerating wound closure, improving skin architecture, and promoting hair follicle neogenesis and tissue regeneration.

In this study, researchers developed a novel temperature-sensitive biopolymer-based drug delivery system that enhanced the transdermal delivery of ISX9, a neurogenesis inducer, resulting in more effective hair follicle regrowth and signal pathway activation in vivo compared to traditional topical application.

This review highlights the roles of key transcription factors and signaling pathways in regulating olfactory epithelium regeneration, discussing recent advances in single-cell and spatial transcriptomics as well as organoid models to enhance understanding of olfactory regeneration mechanisms.
