Neutrophil Extracellular Traps Impair Regeneration

This study found that self-noncoding dsRNA activates TLR3 to stimulate intrinsic retinoic acid synthesis, promoting new hair follicle formation in wounded mice and showing similar gene expression changes in humans treated with rejuvenation lasers.

This study explored the regenerative abilities of the African spiny mouse's skin, revealing more robust wound-induced hair follicle neogenesis compared to laboratory mice and highlighting unique features of its hair and wound response.

This study found that activating the Sonic hedgehog pathway in scarring wounds can remodel the dermis to promote hair follicle regeneration, highlighting a potential new approach to enhance healing.

This study suggests that M2 macrophages play a key role in promoting wound-induced hair neogenesis in mice by producing growth factors like Igf1 and Fgf2.

This study found that transforming growth factor-β1 and CX3CR1 are crucial for recruiting specific macrophages essential for wound-induced hair growth in mice.

The researchers reported that noncoding double-stranded RNA promotes wound-induced hair neogenesis in mice by modulating prostaglandin and Wnt levels.

This study shows that macrophage-induced TNF signaling can activate hair follicle stem cells and promote new hair follicle formation after wounding by regulating AKT/β-catenin pathways.

This study found that hair follicles in mice and humans can convert wound-related myofibroblasts into adipocytes, suggesting a potential pathway to reduce scar formation by activating BMP signaling.

The researchers reported that dsRNA from damaged skin activates TLR3, promoting hair follicle regeneration, while TLR3-deficient animals fail to initiate this process, suggesting potential therapeutic approaches for hair neogenesis.

This study found that fibroblast growth factor 9, initially secreted by γδ T cells, plays a key role in modulating hair follicle regeneration in mice after skin wounds.

This study reports the first instance of skin autotomy in mammals, specifically in African spiny mice, and suggests they may possess a greater regenerative capacity than previously understood, possibly offering insights for regenerative medicine.

This study found that in vivo confocal scanning laser microscopy accurately quantifies neogenic hair follicles in mice, producing results similar to histology while avoiding fixation artifacts.

Hair follicles can regrow in wounded adult mouse skin using a process like embryo development.

This paper provides evidence supporting the formation of new hair follicles in adult humans, building on findings previously demonstrated in rabbits.
