Nuclear texture during the cell cycle in acute lymphoid leukemia.
Description of morphological and textural changes during cell cycle were studied in 31 diploid Acute Lymphoid Leukemia ALL cases. Feulgen stained nuclei were measured by image analysis. Cells with 2C, 3C and 4C content of DNA were considered as being in G1, S and G2 phase of cell cycle respectively. The main observed transformations associated with cell cycle were continuous increases in nuclear size and in quantities of black/white chromatin clumps and points. An overall correct classification of 92.5% was achieved by multivariate data analysis. However, significant differences between A L L cases were noticed.
