Figure 1From: Hypoxia and hypoglycaemia in Ewing's sarcoma and osteosarcoma: regulation and phenotypic effects of Hypoxia-Inducible Factor Expression of HIF in Ewing's sarcoma. (a) HIF-1α and (b) HIF-2α expression in Ewing's tumour cells; scale bar = 50 μm. Expression of HIF-1α (c) co-localises with that for cleaved caspase 3 (d); scale bar = 100 μm.Back to article page
