title: [Effect of alpha-thrombin on DNA synthesis and excretion by lymphocytes].
abstract: Thrombin-activated spleen lymphocytes of mice synthesize 1.5 times more DNA than unstimulated cells. The proportions of palindromic sequences in the newly-synthesized nuclear DNA of control and thrombin-stimulated lymphocytes are 1.1% and 0.5%, respectively. Both the control and thrombin-stimulated lymphocytes release about 10-12% of the newly-synthesized cellular DNA into the culture medium. It is shown that the newly-synthesized DNA of viable, rather than non-viable cells, is the source of extracellular DNA.
