Cytogenetic analysis of gossypol acetate-induced murine myxosarcoma demonstrated a stemline of 78 chromosomes and the presence of three marker (M) chromosomes produced by robertsonian translocation. Tumor cells at passage 1 that contain chromosomes M1 and M2 were nontumorigenic, whereas cells at passage 3 were tumorigenic in syngeneic mice and showed M1, M2, and M3. The presence of M3 has been implicated to be responsible for the tumorigenic phenotype.
