摘要: Bone-marrow-derived cells facilitate tumour angiogenesis, but the molecular mechanisms of this facilitation are incompletely understood. We have previously shown that related EG-VEGF and Bv8 proteins, also known as prokineticin 1 (Prok1) 2 (Prok2), promote both tissue-specific angiogenesis haematopoietic cell mobilization. Unlike EG-VEGF, is expressed in bone marrow. Here we show implantation mice resulted upregulation CD11b+Gr1+ myeloid cells. identified granulocyte colony-stimulating factor a major positive regulator expression. Anti-Bv8 antibodies reduced mobilization elicited by factor. Adenoviral delivery into tumours was to angiogenesis. inhibited growth several suppressed treatment cells, peripheral blood tumours. The effects anti-Bv8 were additive those anti-Vegf or cytotoxic chemotherapy. Thus, modulates from marrow during development promotes locally.
