title: Stimulation of quiescent 3T3 cells by phosphatidic acid-containing liposomes.
abstract: Liposomes containing phosphatidic acid were capable of stimulating DNA synthesis in quiescent Swiss 3T3 cells while liposomes composed of other phospholipids were not. These results show that liposomes, which are usually employed to deliver non-lipid molecules into cells, can themselves have profound effects on cell growth. The possible mechanism of phosphatidic acid-mediated cell stimulation and its relation to other growth factors are discussed.
