Similar was later confirmed by Choi et al. [65] demonstrating that also adipose MSCs target brain tumor-initiating cells from glioblastoma, medulloblastoma, and ependymoma, by releasing potential cytokines, including CXCR4/SDF-1alpha, CCR5/RANTES, IGF1R/IGF-1, IL6R/IL-6, and IL8R/IL-8. The gene discussed is IL6; the disease is ependymoma.
