title: Variability of short-term cultures of HeLa S-3 cells: changes in DNA distributions and rates of DNA synthesis.
abstract: DNA distributions of HeLa S-3 cells in spinner culture exhibit significant time-dependent changes. The major differences appear to occur in the S-phase region. Significant changes in the rates of DNA synthesis in several S-phase subcompartments correlated well with the changes in the DNA distributions. It is proposed that fluctuations in these rates of DNA synthesis are a reflection of the inherent instability of these abnormal, heteroploid cells.
