Abstract: | Summary The development of the tissue culture technique has enabled us to cultivate mammalian cells in a way which is similar to that in use with bacterial cells. As such, the nutritional requirements of mammalian cells in culture have been studied with simplicity and exactness. According to Eagle's extensive works it is accepted that cultured cells generally require 13 amino acids, 8 or 9 vitamins, glucose and 6 inorganic salts. However, although some cultured cells have a capacity for the biosynthesis of Eagle's essential nutrients and others require non-essential nutrients.In this review we will discuss the amino acid and vitamin requirements of cultured cells, and a cell line (R-Y121B · cho) which propagates continuously in a chemically defined medium containing 11 amino acids, 7 vitamins, glucose and 6 ionic salts. Arginine, glutamine, tyrosine and choline are synthesized in the R-Y121B · cho cells. |
