Mesenchymal stromal cells (MSC) exposed to stiff environment lose regeneration potential and acquire a scar-producing myofibroblast (MF) phenotype. We published that 4-weeks culture on soft-tissue-like surfaces not only prevents acute MF features but imprints memory that protects MSC from subsequent mechanical MF activation. Epigenetic methylation of DNA by methyltransferases (DNMTs) memorizes MF phenotype in disease. […]
