Effect of the Ac-EEED peptide on stress fiber formation in aortic SMC and retinal pericytes. SMCs (A, B) and retinal pericytes (C, D) were cultured in 2% serum and incubated with either scrambled peptide (A, C) or Ac-EEED fusion peptide (B, D) for 30 minutes, Cells were then fixed, permeabilized, stained with rhodamine-conjugated phalloidin, and visualized by fluorescence microscopy.
