First, pericyte coverage was detected by examining the expression of NG2+CD146+ tumour blood vessels by immunofluorescence analysis and found that anti-IFNγ increases NG2+ pericyte coverage compared with that observed in cisplatin-treated tumours (Supplementary Figure S4), thus implying that compared with cisplatin, anti-IFNγ enhances the integrity of tumour blood vessels. This evidence concerns the gene MCAM and neoplasm.
