The expression of CSF1R, CD63, CD83, VCAM1 and VWF was decreased in hCMEC/D3 the coculture with GBM cells compared to hCMEC/D3 monoculture, while the expression of CD1D, CD38, CD69, CD96 and KLRD1 was increased due to the co-culture independently of the PCDHGC3 expression status. This evidence concerns the gene PCDHGC3 and glioblastoma.
