[Physiological Media in Studies of Cell Metabolism]

Changes in cell metabolism accompany the development of a wide spectrum of pathologies including cancer, autoimmune, and inflammatory diseases. Therefore, usage of inhibitors of metabolic enzymes are considered a promising strategy for the development of therapeutic agents. However, the investigation of cellular metabolism is hampered by the significant impact of culture media, which interfere with many cellular processes, thus making cellular models irrelevant. There are numerous reports that show that the results from in vitro systems are not reproduced in in vivo models and patients. Over the last decade a novel approach has emerged, which consists of adaptation of the culture medium composition to that closer to the composition of blood plasma. In 2017-2019, two plasma-like media were proposed, Plasmax and HPLM. In the review, we have summarized the drawbacks of common media and have analyzed changes in the metabolism of cells cultivated in common and plasma-like media in normal and pathological conditions.
