Co-culture of BTICs and hAT-MSCs showed different expression levels of several cyto-chemokines compared with co-culture of BTICs and HFF1: SDF-1, RANTES, IL-6 and IL-8 in medulloblastoma-BTICs, SDF-1, RANTES, IL-6 and IL-8 in AT/RT-BTICs and SDF-1, IL-6, IL-8 and IGF-1 in glioblastoma-BTICs (Table 1). Here, CXCL8 is linked to glioblastoma.
