Abstract: Ascites tumor cells of Watanabe II tumor of rats usually have a chromosomal projection or projections protruded from the nuclear surface in about 20 per cent of tumor cell population in every transplant generation. They are covered with nuclear membrane and contain a number of fine chromatin granules similar to those of the nuclei from which they have projected. Although they are parts of the nuclei at resting stage, they begin to show chromosome constitution at prophase and become longer chromosome thereafter. It is highly probable that a extremely long and other larger chromosomes characteristic to Watanabe II tumor occur as chromosomal projections in resting nuclei because of their larger size, judging from the observation of the mitotic course of the tumor cells having such marker chromosomes.
