Lack of vascularization results in increased demand for oxygen and creates a defined feature of the tumor microenvironment known as tumor hypoxia。 It is well established that in response to hypoxia， hypoxia-inducible factor-1 alpha (HIF-1 alpha) is induced which is an important factor in angiogenesis， invasion and metastasis。 In turn， HIF1 alpha regulates the expression of angiogenic factors， such as vascular endothelial growth factor (VEGF)。 Ascribed to abnormal characteristics of tumor angiogenic networks， antiangiogenic therapy approaches can even worsen the hypoxic condition and can create cancer cells with stemness features。 Hence oxygen delivery via perfluorocarbon (PFC) to hypoxic sites seems to result in unstable HIF expression and consequent inactivation of angiogenesis cascade and metastasis and therefore， inhibition of cancer cells stemness。
