Abstract

Neuroblastoma (NB) is one of the most common pediatric solid tumors and, like most human cancers, is characterized by a broad variety of genomic alterations. Although mesenchymal stem cells (MSCs) are known to interact with cancer cells, the relationship between MSCs and metastatic NB cancer cells in bone marrow (BM) is unknown. To obtain genetic evidence about this interaction, we isolated ΒΜ-derived MSCs from children with NB and compared their global expression patterns with MSCs obtained from normal pediatric donors, using the Agilent 44K microarrays. Significance analysis of microarray results with a false discovery rate (FDR) <5% identified 496 differentially expressed genes showing either a 2-fold upregulation or downregulation between both groups of samples. Comparison of gene ontology categories of differentially expressed genes revealed the upregulation of genes categorized as ‘neurological system process’, ‘cell adhesion’, ‘apoptosis’, ‘cell surface receptor linked signal transduction’, ‘intrinsic to membrane’ and ‘extracellular region’. Among the downregulated genes, several immunology-related terms were the most abundant. These findings provide preliminary genetic evidence of the interaction between MSCs and NB cancer cells in ΒΜ as well as identify relevant biological processes potentially altered in MSCs in response to NB.
