We are aware that monotherapy may not work for malignant tumors such as glioblastoma. Search for novel key molecules in these devastating diseases is inevitable. With our patient-derived CSC models and their xenograft models, we have discovered various key molecules and their targeted lead compounds that attenuate various phenotypes in CSCs.
