In this study, researchers used a chemical cocktail and hydrogel microspheres to successfully guide fibroblasts into dermal papilla cells, promoting wound healing and in situ hair follicle regeneration while reducing scar formation, in both in vitro and in vivo experiments.

In a study using a rat model of hypertrophic scars, researchers found that gamma-irradiated human amniotic fluid improved wound healing, collagen remodelling, immune response, and scar characteristics more effectively than saline or non-irradiated amniotic fluid, indicating its potential for clinical applications in scar management.

This study found that keratin-gelatin composite films effectively promoted early wound healing and full-thickness skin graft acceptance in dogs, outperforming bFGF-gelatin films.

This study found no evidence of increased keratinocyte proliferation in acne vulgaris, suggesting that other mechanisms may be responsible for hyperkeratinization in acne pathogenesis.

Accidental injection of hyaluronic acid caused temporary hair loss and skin damage, but treatment restored hair and healed the skin.

This article describes a case of localized trichorrhexis nodosa in a patient with otherwise normal hair, highlighting the condition's response to trauma and diagnostic process but reporting no new clinical findings.

This study found that high skin expression of amphiregulin in acute graft-versus-host disease was associated with severe disease grade, poor overall survival, and increased non-relapse mortality.

This study found that PCL-based nanofiber scaffolds enhanced cell proliferation and extracellular matrix deposition, suggesting they show promise as a cell delivery system for improving skin wound healing.

This study observed that microneedling-induced microinjury promotes hair growth via a TNF-α, Wnt, and VEGF pathway, while blocking TNF-α inhibits this process.

This study presents a novel, scalable method for preparing highly hair-inductive tissue grafts using a bioprinter, which enhances hair follicle regeneration in mice, although most hair shafts remained beneath the skin.

This study suggests that pilomatricoma can differentiate towards various hair follicle structures, including hair matrix, hair cortex, follicular infundibulum, outer root sheath, and hair bulge.

In this study, MSC-laden silk nanofiber hydrogels accelerated wound healing and enabled scarless skin regeneration with hair follicles, outperforming MSC-free hydrogels in repairing full-thickness skin defects.

This case report introduces a novel instance of long-term cutaneous neoplastic degeneration following artificial hair implantation, a previously unreported complication in such procedures.

In this study, microporous electrospun scaffolds pre-seeded with dermal fibroblasts accelerated wound healing and improved dermal matrix structure and hair follicle regeneration compared to acellular scaffolds in a rat model.

This research reported that dermal progenitor cells can enhance split-thickness skin graft outcomes by improving dermal layer qualities and reducing itch and offer potential in skin wound healing using a flowable hydrogel for better cell delivery and survival.

This study demonstrated that a newly developed polypeptide-protein hydrogel with vascularization and antibacterial properties promoted tissue regeneration and hair follicle formation in infected wound healing.

This study found that crosstalk between fibroblasts and endothelial cells significantly contributes to hypertrophic scar formation by enhancing fibroblast activity through cytokine secretion, with pathway analyses suggesting molecular targets for potential therapeutic interventions.

This study reported that a novel chitosan/polyvinyl alcohol nanofiber sponge effectively enhances the hair follicle-inducing ability of dermal papilla multicellular spheroids in a mouse model.

In this study, keratin hydrogels derived from human hair were found to significantly enhance nerve regeneration in a mouse model, acting effectively as scaffolds by influencing Schwann cell behavior.

This article discusses the potential role of telocytes in skin regeneration and the need to understand their interaction with platelet-rich plasma, reporting no new experimental results.

This study introduces Immunoguided Cutaneous Regeneration as a potential framework for understanding skin allotransplantation, suggesting that regeneration may depend on the preserved extracellular matrix and a regulated immune response.

This study found that increasing commensal bacterial load on the skin enhances wound-induced hair follicle neogenesis in mice, mediated through IL1R-MyD88 signaling pathways.
