title: [Karyotypic variability of a tumor cell population in the process of prolonged growth in the body].
abstract: An ascite variant of spontaneous mammary gland tumor of C3H/Sn mice was transplanted subcutaneously into syngenic mice. During the tumor growth (150 days) some alterations occur in the genetical structure of the tumor population: a change in the stem line, the increase and a further decrease of nearoctaploid cells.
