Interference of phosphatidylcholines with in-vitro cell proliferation - no flock without black sheep

摘要

According to early experiments with natural extracts, phosphatidylcholines (PCs) are widely considered essentially non-toxic. In addition to these physiological mixed-chain PCs, many different synthetic diacyl-PCs are currently available, but they have never been systematically evaluated for any interference with cell proliferation. We thus investigated the cell proliferation of several cell lines in the presence of various liposomes consisting of a single PC component and cholesterol.
