Although OATP+ IBA1+ cells and OATP+ blood vessels only made up a small proportion of the tissue-wide average OATP intensity (Figure 3A–D), we hypothesized that the mean average intensity of each OATP isoform would be higher in GBM vasculature and myeloid populations when compared to their respective non-tumor cells. The gene discussed is SLCO1A2; the disease is neoplasm.
