[A kinetic analysis of the growth of transplanted tumors and their metastasis].

Under study were kinetic regularities in development and incorporation of tritium labelled thymidine into cells of two experimental metastasizing tumors -- Zajdela ascites hepatoma and Walker carcinosarcoma, transplanted intratesticulary. Primary tumors and their metastases in regional lymph nodes show certain differences relative both to the rate of the process and intensity of the DNA synthesis, and relative number of cells with incorporated labelled thymidine.
