The protein expression of angiogenesis-related factors (VEGFA, TGF, PDGF, CD31, CD34) were tested by IF. (A–E) Left column, DAPI channel showing blue fluorescence, middle column biomarkers channel showing red fluorescence from the liposomes, right column is DAPI with biomarkers channels merged. Bars = 50 μm. The quantitative analysis of average fluorescence intensity obtained from ImageJ software (F–J) (400×, x ± s, n=3, *P<0.05, **P<0.01).
