The expression pattern of P-AXL in hypercellular areas was further classified as focal (10-50%; A., C.) or diffuse (≥ 50%; B., D.). Focal expression was seen e.g. in pseudopalisades (A.; dashed line) or scattered clusters of tumor cells (C.; arrows). Other GBM samples demonstrated broad/global P-AXL expression (B., D.) which was pronounced in areas which often showed a typical herringbone-like pattern (D.; arrowheads). (Scale bar: 50 μm).
