Abstract

The monoclonal antibody Ki-67 detects a nuclear antigen that is present only in proliferating cells. The aim of the present investigation was to clarify whether the Ki-67 nuclear antigen is restricted in its expression to certain phases of the cell cycle. All experiments consistently showed that the Ki-67 nuclear antigen is present in S, G2, and M phase, but is absent in G0. However, the results concerning Ki-67 antigen expression in G1 phase varied: cells passing the early events of mitogen triggered transition from G0 to G1, i.e., G1T and first G1A, lacked the Ki-67 nuclear antigen, whereas G1 cells after mitosis were constantly Ki-67-positive. This result suggests that after mitosis cells might not follow the same metabolic pathways as G0 cells do when entering G1 for the first time. Therefore, we suggest that the early stages of mitogen stimulation represent initial sequences of proliferation and not parts of the cell cycle. Because our data show that the Ki-67 nuclear antigen is present throughout the cell cycle, immunostaining with monoclonal antibody Ki-67 provides a reliable means of rapidly evaluating the growth fraction of normal and neoplastic human cell populations.

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.
