April 2025 in “bioRxiv (Cold Spring Harbor Laboratory)” In this study, aged mice showed better regenerative skin outcomes than young mice, linked to a specific fibroblast subpopulation and enhanced signaling interactions that promote regeneration. EREG treatment improved young mice's skin regeneration, suggesting potential for scarless therapies.

August 2020 in “Cell stem cell” In this study, researchers found that extrafollicular progenitors marked by Hic1 are the main contributors to reparative fibroblasts in wound repair, with potential to modulate healing outcomes through genetic and pharmacological interventions.
April 2016 in “Journal of Investigative Dermatology” This study found that the CD301b-expressing subpopulation of macrophages plays a crucial role in promoting reparative processes during the mid-stage of skin wound healing in a mouse model.

September 2018 in “International Journal of Molecular Sciences” In this study, researchers found that exposure to PM10 significantly increased inflammation and impaired collagen synthesis in human dermal fibroblasts, suggesting PM10 contributes to skin aging through these mechanisms.
July 2026 in “Frontiers in Immunology” This research proposes a comprehensive "four-dimensional technology toolbox" for reprogramming wound-repair cells, aiming to treat chronic non-healing wounds like diabetic foot ulcers by altering fibroblasts, keratinocytes, and macrophages to regenerative phenotypes, and addressing clinical translation challenges.
