Table 3: Expression of angiogenesis genes by freshly isolated ALDHbr cells and ALDHbr cells cultured in transwells under hypoxic conditions with and without HUVEC networks. Cultures were maintained as described in the text. Values are fold change in mean expression of genes in the angiogenic array that were significantly (p<0.05) upregulated (positive values) or down regulated (negative values). Gene expression was measured by QRT-PCR.
