Part Two: The effect of fruit extract on CRL-2606 production of PGE2 Effect of anthocyanin rich fruit extracts on endothelial cells'PGE2 production Epidemical experiment shows that phenolics in fruits and vegetables may prevent the occurrence of chronicle cardiovascular heart disease. To investigate the activity of fruit extracts on artery blood vessel cells, we chose CRL-2606 cell line, a normal iliac artery endothelia cells. Using indomethacin as control, we investigate the effect of blueberry extracts, blackcurrant extracts, chokeberry extracts, cyanidin3-glucoside, and malvidin3-glucoside on the PGE2 production of CRL-2606 cells.
