Expression of the Neural RNA-Binding Protein Musashi1 in Pediatric Brain Tumors

Abstract excerpt

Musashi1 (MSI1) is an evolutionarily conserved RNA-binding protein, selectively expressed in neural stem cells (NSCs) and considered a versatile marker for normal NSCs and tumor cell diagnosis. Here, we examined MSI1 expression in primary pediatric brain tumors, medulloblastomas and ependymomas, by double immunostaining with lineage phenotypic markers (Lin). These tumors highly express MSI1 and are heterogeneous,...
