Table 3.

Fraction of cells in different cell-cycle phases of monolayer cultures and spheroids at 10^th day, 30^th day and at saturation. As the spheroid grows, a slow and gradual increase in the fraction of cells in the quiescent G0 phase is accompanied by a corresponding decrease in G1, S, G2 and M phase cells.

	Spheroid at T = 10 days	Spheroid at T = 30 days	Saturated spheroid
G0 phase fraction	0.14	0.19	0.195
G1 phase fraction	0.35	0.27	0.24
S Phase fraction	0.35	0.325	0.3
G2 Phase fraction	0.09	0.085	0.08
M Phase fraction	0.025	0.02	0.015
