Figure 3. — Tumorsphere and colony formation of SP and NSP cells. (A) Representative images of tumorsphere formation from SP (left panel) and NSP (right panel) cells. (B) Average number of tumorspheres/field in SP and NSP cells. Spheres >50 µm in size were counted (P<0.01; n=3). (C) Representative images of colony formation from SP (left panel) and NSP (right panel) cells. (D) Colony formation efficiency in SP and NSP cells. Clusters of >50 cells were counted (*P<0.01; n=3).
