swollen spheroid cell swollen spheroid cell during G0 midori swollen spheroid cell during quiescence spheroid cell with increased cell size during G0 enlarged volume spheroid cell during G0 A cell morphology phenotype in which a cell is shaped in the form of a spheroid, and has a larger volume than normal, when the cell is in G0 phase. In spheroid cells, there is much less difference between the long and short axes of the cell than in wild type. Spheroid cells may shorter than normal, with approximately the same diameter as normal, or they may be enlarged. swollen rounded cell during G0 FYPO:0002942 large spheroid cell during G0 enlarged spheroid cell during G0 swollen spheroid cell during cell quiescence 2013-12-04T14:15:58Z spheroid cell with increased cell volume during G0 Note that fission yeast cells can enter G0 as a result of either glucose starvation or nitrogen starvation, which can be specified in annotations using conditions.
