Expression data for cultured NCI-H1299 parental and spheroid cells as well as their derived xenograft models

Current approaches to the preclinical investigation for novel cancer therapies rely heavily on the use of traditional cancer cell lines maintained in serum-containing conditions. The discrepancy between promising preclinical efficacy and clinical outcome of most novel anticancer agents emphasizes a need for developing predictive preclinical models that preserve the integrity of original patient tumors, including cancer stem cell (CSC) compartment.
