Perfluorochemicals: their applications and benefits to cell culture

The properties of perfluorochemical liquids, particularly their high gas solubility, enables them to be exploited in cell biotechnology. They can facilitate respiratory-gas delivery to prokaryotic and eukaryotic cells in culture; in some systems, they can stimulate production of biomass, yields of commercially important cellular products and, for plant systems, expression of totipotency. The recoverability, and hence recycleability, of perfluorochemicals from aqueous systems makes their routine use a commercially feasible option. This article reviews the applications and beneficial effects of perfluorochemicals in cultured microbial, animal and plant cells, including both aerobic and anaerobic systems.
