Angiogenesis plays a key role in tumor growth and cancer progression. TIE-2-expressing monocytes (TEM) have been reported to critically account for tumor vascularization and growth in mouse tumor experimental models, but the molecular basis of their pro-angiogenic activity are largely unknown. Moreover, differences in the pro-angiogenic activity between blood circulating and tumor infiltrated TEM...

Tumor-mobilized bone marrow-derived CD11b+ myeloid cells promote tumor angiogenesis, but how and when these cells acquire proangiogenic properties is not fully elucidated. Here we show that CD11b+ myelomonocytic cells develop proangiogenic properties during their differentiation from CD34+ hematopoietic progenitors and that Placenta Growth Factor (PlGF) is critical in promoting this ...
