Besides these differences, expression of CD24, CD200 and ABCC5 were upregulated upon stem cell-promoting conditions with highly significant fold changes for CD200 (p < 0.0001) in all three NB cell lines and for CD24 (p < 0.001) and ABCC5 (p < 0.001) in SH-SY5Y cells (Figure 1). The gene discussed is CD24; the disease is neuroblastoma.
