Stem cells play a critical role in cancer development by contributing to cell heterogeneity, lineage plasticity, and drug resistance. We created gene expression networks from hundreds of mouse tissue samples (both normal and tumor) and integrated these … Stem cells play a critical role in cancer development by contributing to cell heterogeneity, lineage plasticity, and drug resistance.
