[Cellular proliferation kinetics of Walker carcinosarcoma, Zajdela's ascitic hepatoma and their metastases to the lymph nodes].

The cell cycle of Walker carcinoma, Zajdela's hepatoma and their metastases into regional lymph nodes are studied. It is shown that cell cycle of metastases is shorter and the labeling index is higher than in primary tumours. The cell cycle shortening in Walker carcinosarcoma metastases is associated with a decrease in the duration of all its phases. The cell cycle of Zajdela's hepatoma metastases decreases with the S-phase length. The cell loss factor of primary tumours is less than that of their metastases. The results of the autoradiographic study correlate with the previously studied sensitivity of primary tumours and metastases to chemotherapy.
