Quantitation of PAF and vessel density in breast tissues. A: The amount of PAF extracted and purified from 18 primary invasive breast carcinomas and 20 controls is expressed as picograms of PAF per milligram of dry tissue. The mean ± SE is indicated (*P = <0.05, t-test). B: Vessel density is expressed as number of endothelial cells or clusters of endothelial cells positive for CD31 (open bar) and CD34 (hatched bar) per microscopic field (see Materials and Methods). Data are expressed as mean ± SE. C: Linear regression analysis between CD31-positive cells and concentration of PAF in breast carcinomas. D: Linear regression analysis between CD34-positive cells and concentration of PAF in breast carcinomas.
