The underlying mechanisms of efferocytosis by fibroblasts were not well understood. We demonstrate that the engulfment of PKH67‐labeled ( green ) apoptotic cells by human primary fibroblasts (HPFs) requires the remodeling of the actin cytoskeleton labeled with tetramethylrhodamine‐B‐isothiocyanate‐conjugated phalloidin ( red ). Confocal microscopy imaging reveals the typical features of phagosome formation that ultimately results in the engulfment of the apoptotic cell in a membrane‐bound vacuole. The nuclei are stained with DAPI ( blue ).
