This study found that chronic UVR exposure in mice and humans leads to a permanent loss of papillary fibroblasts in the upper dermis, which is associated with changes in the extracellular matrix.
May 2024 in “Scientific reports” This study explored the role of Twist2 in fetal wound healing in embryonic mice, observing that its expression was vital for scarless regeneration and normal hair follicle formation; Twist2 knockdown led to visible scars and defective follicle formation.
March 2024 in “Research Square (Research Square)” In this study, researchers found that the protein Twist2 plays a crucial role in scarless wound healing in early embryonic mouse skins, with its knockdown leading to visible scarring and defective hair follicle formation, suggesting potential therapeutic targets for reducing scars and promoting regeneration.

April 2025 in “International Journal of Biological Macromolecules” This study found that Forskolin-loaded carboxymethyl chitosan-silk nanofiber hydrogels promoted wound healing by accelerating wound closure, enhancing neovascularization, and supporting hair follicle regeneration, while also being non-toxic and encouraging the proliferation of certain cell types.

October 2010 in “Tissue Engineering Part A” This study found that tissue-engineered skin using mouse fibroblasts successfully supported hair growth after grafting, but similar success was not observed using human fibroblast-derived tissue.
