Hyaluronan, CD44 and HYAL2 stainings in grade II and grade IV astrocytomas. Hyaluronan (a and b) and CD44 (c and d) staining intensities are strong both in grade II (a and c) and grade IV (b and d) astrocytomas. CD44 is markedly expressed in the perivascular areas (d, insert, black arrows). HYAL2 staining intensity increases according to WHO grade (e and f). Endothelial cells show HYAL2 immunopositivity (e and f, black arrows). Scale bar in F is 50 μm
