Figure 6.
Scored cellularity of low grade CSA and dedifferentiated CSA. The cellularity of monolayer cultures (2D), spheroids (3D) and tumors were evaluated according to pathologic criterion. Cellularity were semi-quantitatively divided into five intervals, from 0–20% to 80–100% and scored correspondingly as level 1 to 5. The low grade and dedifferentiated CSA groups were scored separately. *p < 0.05, **P < 0.001.
