This study introduced fibronectin nanogel microneedles (FNG MNs) that demonstrated improved tissue penetration and transdermal delivery, restoring skin homeostasis in a photoaged mouse model and enhancing collagen deposition and angiogenesis in a diabetic wound rat model.

This study designed fibronectin nanogel microneedles, reporting their potential to enhance tissue repair by improving collagen organization, reducing inflammation, and promoting angiogenesis in both photoaged and diabetic wound models.

This study reported that a newly designed multifunctional conductive hydrogel, PrM, combined with electrical stimulation significantly accelerated wound healing, achieving 95.9% healing in a mouse model on day 10, by enhancing regenerative processes and downregulating TNF-α signaling under electrical treatment.

This review discusses recent advancements in hair follicle organoid technology for alopecia treatment but presents no new experimental results, emphasizing the potential for clinical applications and drug screening.

This research observed that removing RNase L in mice enhances regenerative capacity through increased IL-36 and wound-induced hair neogenesis, highlighting RNase L as a gene that represses regeneration by moderating immune responses during viral infections.

This study reports that using a hydrogel-based therapy that dynamically regulates reactive oxygen species helps achieve skin regeneration in infected wounds, promoting organized dermal architecture with improved hair follicle and blood vessel formation, rather than scar formation.

In an animal study with a skin defect model, this research reported that curcumin-loaded hydrogels made from recombinant humanized collagen and an eco-friendly crosslinker enhanced wound repair by promoting angiogenesis, granulation tissue formation, and hair follicle neogenesis, while providing antioxidant benefits.

Wnt signaling helps regenerate hair follicles in wounds by reducing skin cell sensitivity to mechanical stress.

This study demonstrates that Wnt signaling plays a crucial mechanoregulatory role in skin regeneration by influencing cellular responses to substrate rigidity, which promotes hair follicle regeneration in the wound-induced hair neogenesis model.

This study found that RNase L acts as a regeneration repressor gene in mammals, as seen in Rnasel-/- mice which showed increased regenerative capacity and elevated Wound Induced Hair Neogenesis through enhanced IL-36α signaling, suggesting a tradeoff between regeneration and immune regulation.

This study found that tissue damage in adult mice triggers the release of mitochondrial DNA, which activates the TLR9 pathway and influences hair regeneration by recruiting gamma delta T cells, ultimately affecting healing outcomes such as fibrosis.

In this review, the authors explore strategies for inducing scarless skin regeneration by modulating dermal signaling or specific fibroblast subsets to promote the formation of new hair follicles in wounds, particularly focusing on mimicking neonatal skin's regenerative capabilities.

Skin organoids can regenerate hair by forming specific cell units with certain signals.
