E13 fetal mouse fibroblast vesicles may help reduce scarring.

Turning scar-forming cells into fat cells can reduce scarring.

In this study, hair follicle transplantation into nonhealing ulcers promoted rapid wound closure, with differing scar quality and hair growth between the central and peripheral wound areas.

This study found that inadequate thickness of deep dermal tissue in pigs is a key factor leading to fibrosis, with fibrosis likely serving a compensatory function for skin thickness.

This review explores fibroblast heterogeneity in the mammalian dermis and suggests potential therapeutic applications by targeting fibroblast subtypes, but reports no new experimental results.

This review article proposes a possible skin-gut-fibrosis axis, suggesting that gut microbial metabolites may influence the development of keloids and hypertrophic scars by affecting immune responses and fibrotic signaling pathways, although direct evidence in skin fibrosis remains limited.

This review examines the mechanisms behind pathological scarring like hypertrophic scars and keloids, highlights the limitations of current treatments, and suggests that biomaterial-enabled delivery of anti-fibrotic statins, such as atorvastatin, may offer a promising therapeutic avenue for managing these scars.

In this study, researchers used a mouse model to demonstrate that expression of MARCKSL1 in dendritic cells plays a crucial role in modulating fibrotic responses and scar formation during wound healing, suggesting that targeting this expression could offer new therapeutic strategies for scar prevention.

This study tested a microneedle patch on rabbit and pig models to support skin regeneration, revealing that the treatment accelerated wound closure, reduced scar formation, and promoted hair-bearing tissue and follicle growth, suggesting a trauma-guided framework for skin restoration.

This study investigated the role of the glycoprotein Thy-1 in hypertrophic scar formation using a murine model, finding that Thy-1 knockdown reduced scar size and encouraged functional regeneration by influencing the p38MAPK signaling pathway under high-tension conditions.
