In solid cancers, IL4 has been shown to be useful in colorectal cancer stem cell suppression [32], [33], BMP4 was found to induce glioblastoma CSCs to differentiate into non-CSCs [34], and salinomycin, a selective potassium ionophore, could target breast cancer stem cell proliferation and induce differentiation [15]. This evidence concerns the gene BMP4 and glioblastoma.
