Figure 3From: CD133, CD15/SSEA-1, CD34 or side populations do not resume tumor-initiating properties of long-term cultured cancer stem cells from human malignant glio-neuronal tumors Proteomic patterns of MGNT-derived cells forming spheres. Upper panel: two-dimensional gel electrophoresis analysis for TG1, one of the cultures of MGNT-derived cells forming spheres, TG1, at 40 (left) and 160 (right) weeks of culture. Lower panel: the same area of the gel as in the upper panels for protein extracts taken from two other cultures of MGNT-derived cells forming spheres, TG6 and TG7.Back to article page
