CD44 and CD24 status and lung metastasis signature gene expression in MDA-MB-468 and LMD-468 cells. (a) Flow cytometry showing CD44 and CD24 expression in MDA-MB-468 and LMD-468 cells. (b) Expression of select lung metastasis signature genes was determined by Northern blot analysis. COX, cyclo-oxygenase; CXCR, CXC chemokine receptor; MMP, matrix metalloproteinase; UPA, urokinase plasminogen activator.
