We have studied the interactions of liposomes with human skin fibroblasts and mouse P815Y mastocytoma cells in culture, and the perfused rat liver, with the following findings. 1. In all the systems studied serum was found to cause an increase in the uptake of a [14C]cholesterol label into cells from anionic and neutral liposomes and a decrease in the uptake of the label from cationic liposomes. 2. Evidence suggests that albumin enhances the exchange/transfer of [14C]-cholesterol between liposomes and cultured cells. 3. With [14C]cholesterol in the liposome bilayer and [3H]methotrexate entrapped in the aqueous spaces of the liposome, the alpha- and beta-globulin fractions of serum decreased the transfer of both labels from cationic liposomes into cultured cells and the perfused rat liver. The beta-globulin fraction caused increased leakage of methotrexate from fluid liposomes of all charges. 4. The alpha- and beta-globulin fractions of serum appear to enhance the uptake of anionic liposomes into the perfused rat liver.
