Abstract

Twelve n-amino acids (arginine, cystine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, tyrosine, and valine) have been found essential for the growth of two mammalian cell lines in tissue culture, a mouse fibroblast' (strain L) (1) and a human uterine carcinoma cell (strain HeLa) (2).The minimal vitamin requirement of these cell lines has also been defined (3).As will be shown here, under the conditions of the present experiments, glutamine proved similarly essential for the survival and growth of both cell lines.In a medium containing the twelve amino acids previously shown to be essential, the seven demonstrably essential vitamins, glucose, electrolytes, and serum protein, both the mouse fibroblast and the human carcinoma cell degenerated and died unless the medium was supplemented with glutamine.The quantitative aspects of this glutamine requirement, and the limited degree to which it could be satisfied by glutamic acid, are described. Methods and MaterialsThe methods of maintaining stock cultures of the two cell lines, of setting up replicate cultures with the various experimental media, and of cell enumeration to evaluate the growth response have been described in previous papers dealing with the amino acid and vitamin requirements of the mouse fibroblast (1, 3) and the HeLa carcinoma cell (2, 3).A helpful modification in the cell-counting, procedure has been the use of disodium Versenate (disodium salt of ethylenediaminetetraacetic acid) to disperse the cells, instead of mechanically scraping them from the surface of the culture flask.The flask was drained, and 3 ml. of fresh medium at pH

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
