Abnormal scarring is a major challenge in modern medicine. The central role of myofibroblasts and TGF-β signaling in scarring is widely accepted, but effective treatment options are missing. Autologous fat grafting is a novel approach that has led to significant improvements in the functionality and appearance of scar tissue. While the underlying mechanism is unknown, the potential role of paracrine effects of adipocytes has been discussed. Hence, with the aim of unraveling the regenerative potential of adipocytes, their effects on in vitro differentiated myofibroblasts and on fibroblasts from hypertrophic scars were investigated. Exposure to adipocyte-conditioned medium significantly decreased the expression of the myofibroblast marker α-SMA and ECM components, indicating the occurrence of myofibroblast reprogramming. Further analysis demonstrated that myofibroblast reprogramming was triggered by BMP-4 and activation of PPARγ signaling initiating tissue remodeling. These findings may pave the way for novel therapeutic strategies for the prevention or treatment of hypertrophic scars.
