Preventing VEGFR1 function using antibodies or by the removal of VEGFR1 ( + ) cells from the bone marrow of wild - type mice abrogates the formation of these pre - metastatic clusters and prevents tumour metastasis , whereas reconstitution with selected Id3 ( inhibitor of differentiation 3 ) - competent VEGFR1 + cells establishes cluster formation and tumour metastasis in Id3 knockout mice .
