Cultured human lung fibroblasts, incubated with cholesterol/phosphatidylcholine vesicles (cholesterol: phosphatidylcholine molar ratio 1:1) incorporated vesicle [3H]-cholesterol linearly for at least 48 h by an exchange process without gaining sterol mass. The incorporation of [3H]cholesterol by the cells was markedly enhanced in the presence of purified bovine serum albumin. A fraction of the incorporated vesicle [3H]cholesterol was esterified by the cells.
培养的人肺成纤维细胞与胆固醇/磷脂酰胆碱囊泡(胆固醇:磷脂酰胆碱摩尔比为1:1)一起孵育,通过交换过程线性摄取囊泡[3H] - 胆固醇至少48小时,且没有获得固醇质量。在纯化的牛血清白蛋白存在下,细胞对[3H]胆固醇的摄取显著增强。细胞将一部分摄取的囊泡[3H]胆固醇酯化。
