Stimulation by serum of multiplication of stationary chicken cells

Temin, Howard M.·1971·Journal of Cellular Physiology

Abstract

When serum was added to cultures of stationary chicken fibroblasts, there was an increase in the percentage of cells synthesizing DNA after a delay of about five hours. If the serum was removed before DNA synthesis began, some cells were still found to start DNA synthesis and to enter mitosis. The delay between the time of addition of serum and the start of DNA synthesis was not affected by the type of serum, the concentration of serum, nor the means of preparing the stationary cells. However, all of these factors affected the proportion of cells stimulated by serum. If two pulses of serum were given immediately following each other, their effects were synergistic. If there were twelve hours between them, there was no effect of the first pulse. These results were summarized in a new model of the cell cycle which subdivided the G1 phase into Gla, b, and c. The effects of serum were seen in a balanced salt solution, and were sensitive to several metabolic inhibitors.

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Suboptimal conditions such as high cell density or insufficient serum can drive cells into quiescence.

    “Subsequent studies demonstrated that sub-optimal conditions such as high cell density7 or serum insufficiency8 could drive cells into this quiescent state.”

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.
