Areas of Glioblastoma Tumors Correlate with Separate Subtypes of Glioma Stem Cells, Respond Better to Combination Treatment
University Hospitals Cleveland Medical CenterStudy in journal Nature Medicine demonstrates, for the first time, that glioblastoma (GBM) is driven by two distinct subsets of cancer stem cells. Moreover, each subtype of glioma stem cells is driven by distinct transcriptional programs for growth and treatment resistance, and these different cell populations correspond to well-known morphological differences within the GBM itself. More importantly, the researchers found that while chemotherapeutic agents targeting each subtype achieve modest efficacy alone, they are synergistic when combined as demonstrated in a mouse model.
