Immunohistochemical analysis of nestin expression in conventional osteosarcomas. Strong diffuse cytoplasmic nestin immunostaining in majority of tumor cells; sample 16 (a). Strong cytoplasmic nestin immunostaining in a subset of tumor cells; sample 11 (b). Medium to strong cytoplasmic nestin expression in a minority of tumor cells dispersedly; sample 17 (c). Glioblastoma multiforme was used as a positive control (d). Immunoperoxidase with Gill's hematoxylin counterstain. Bars, 100 μm.
