the methods of isotopic and fluorescent labels have shown that interaction of cells of neuroblastoma s 1300 n 18 with small one-layer neutral liposomes prepared of the egg phosphatidyl choline with the addition of different amounts of cholesterol is realized by two mechanisms : the transmembrane transfer of cholesterol by the concentration gradient and membrane lipid metabolism proper , the ratios of cholesterol phospholipids in the biological and artificial membranes being equal .
