Representative images of selected antibody staining in static and growing VS are shown in (Fig. 1B), identifying Schwann (S100B), vascular (smooth muscle actin) and immune-related cells (CD68, Iba1, CD74 and CD163 for myeloid, CD45 and CD8a for T cells) within the tumour micro-environment. This evidence concerns the gene PTPRC and neoplasm.
