The effect of oil body bound oleosin-rhFGF9 of transgenic safflower was analyzing the activity of NIH/3 T3 cells. Various concentrations (0.82–212 ng/ml) of wild-type (WT) and oil body bound oleosin-rhFGF9 or rhFGF9 (FGF9 from E.coli) were used in NIH/3 T3 cells. DMEM was used as a blank control. Proliferation was quantified by measuring the absorbance at 570/630 nm
