Figure 1 Sox2 Expression Underlies Cancer Stem Cell Function In two distinct mouse cancer models, Sox2+ cells initiate tumor growth and spawn differentiated cell lineages that recapitulate primary tumor composition. In medulloblastoma, Sox2+ cells are quiescent and, in lineage tracing experiments, found to be chemotherapy-resistant, thus promoting tumor recurrence. Conditional deletion of Sox2 from the epidermis in squamous cell carcinoma triggers tumor regression, and Sox2+ cells are responsible for tumor initiation and growth. Tumor propagation by the founder cells appears to recapitulate embryonic and stem cell differentiation programs that operate within normal tissues.
