Abstract

A simple method is described for introducing exogenous fatty acids into the membrane phospholipids of the murine leukemia cell EL-4, and into the membrane phospholipids of resting mouse lymphocytes. The method involves culturing of the cells with free or methylated fatty acids at concentrations up to 50 μg/ml. The presence of serum in the culture medium does not interfere with fatty acid uptake, but does increase the growth rate and viability of the cells. Membrane lipid composition returns to normal after the cells are grown in medium without exogenous fatty acid. Fractionation of the cell membranes confirmed that exogenous fatty acids were incorporated into the phospholipids of the plasma membrane.
