Expression data from hiPSCs-NSCs towards U87. Homo sapiens

Neural stem cells can migrate towards tumors of both neural and non-neural origins, which is crucial for the success in treating disseminated tumors. Although the understanding of the molecular mechanisms underlying NSC tumor tropism is limited, it has been noted that several cytokines, growth factors and receptors direct the migration in vitro. A proper understanding of the basic molecular mechanisms of NSC migration towards tumors, especially identification of key cellular regulators of the migration, will have important implications in improving the effectiveness of engineering and employing NSCs as tumor therapy agents. We compared gene expression profiles between migratory and non-migratory hiPSC-NSCs towards cancer cells using cDNA microarray profiling. Overall design: We collected human iPSCs derived NSCs migrating and not migrating towards human U87 glioma cells in an in vitro migration system for total RNA extraction and hybridization to Affymetrix microarrays
