Metabolic flux rewiring in mammalian cell cultures

Metabolic flux rewiring in mammalian cell cultures.

Continuous cell lines (CCLs) engage in 'wasteful' glucose and glutamine metabolism that leads to accumulation of inhibitory byproducts, primarily lactate and ammonium. Advances in techniques for mapping intracellular carbon fluxes and profiling global changes in enzyme expression have led to a deeper understanding of the molecular drivers underlying these metabolic alterations. However, recent ...

Towards dynamic metabolic flux analysis in CHO cell cultures.

Chinese hamster ovary (CHO) cells are the most widely used mammalian cell line for biopharmaceutical production, with a total global market approaching $100 billion per year. In the pharmaceutical industry CHO cells are grown in fed-batch culture, where cellular metabolism is characterized by high glucose and glutamine uptake rates combined with high rates of ammonium and lactate secretion. The...

Biosafety of Mammalian Cell Cultures

Enzyme activity levels in mammalian cell cultures.

Improved methods for growing animal cells in culture have led to their wide use as a tool in a variety of disciplines in biology. Cultures from many different anatomical origins are available and purification of several of them has been effected by the method of single clone isolation (1). The exact nature of the cultured cells and their relationship to the organ of their origin is, however, un...
