[Cell proliferation kinetics in sarcoma 37. I. The changes in the size of the cell and the nucleus over the generative cycle].

Using morhometric autoradiographic and cytophotometric methods, the author examined the changes in the size of the nucleus, and of the cell as well as of the ratio: surface of the nucleus (surface of the cytoplasma in sarcoma-37 ascitic variant in accordance with their position in the generative cycle. The cells with small sizes of the nucleus 30 microns 2 were not labelled with 3H-thymidine and were found mainly in Gi-phase of the cycle. The labelled cells with nuclear sizes of 40-60 microns 2 were at the S-phase of the cycle.
