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.
February 2026 in “Nano Research” In this study, researchers developed a near-infrared-responsive nanoplatform that synergistically enhances chronic wound healing by accelerating mitochondrial restoration and immune modulation, leading to enhanced wound repair and high-quality healing in diabetic rat models.
December 2023 in “bioRxiv (Cold Spring Harbor Laboratory)” This study observed that extracellular matrix scaffold membranes performed less effectively in wound healing for aged mice compared to younger ones, with senescent SPP1+ macrophages potentially hindering epidermal and fibroblast repair abilities.

February 2021 in “Journal of Investigative Dermatology” This review examines the complexities of age-related skin healing and discusses how translating findings from model organisms to humans could enhance understanding and treatment of impaired regeneration in aging populations, but it reports no new clinical results.
