Immunohistochemical analysis for anti-human Nestin and anti-human CD133 antibodies. Paraffin-embedded sections of representative gliomas and normal brain tissues were stained with the antibodies against human Nestin and CD133. The photographs of A and C are normal brain tissues which showed negative or weak staining for Nestin and CD133, respectively. In contrast, the glioblastomas that have high expression levels of Nestin and CD133 with dense and spotty staining were shown in B and D, respectively.
