Intermediate Monocytes but Not TIE2-Expressing Monocytes Are a Sensitive Diagnostic Indicator for Colorectal Cancer
We have conducted the first study to determine the diagnostic potential of the CD14++CD16+ intermediate monocytes as compared to the pro-angiogenic subset of CD14++CD16+TIE2+ TIE2-expressing monocytes (TEMs) in cancer. These monocyte populations were investigated by flow cytometry in healthy volunteers (N = 32) and in colorectal carcinoma patients with localized (N = 24) or metastatic (N = 37) ...
متن کاملTIE2-expressing monocytes/macrophages regulate revascularization of the ischemic limb
A third of patients with critical limb ischemia (CLI) will eventually require limb amputation. Therapeutic neovascularization using unselected mononuclear cells to salvage ischemic limbs has produced modest results. The TIE2-expressing monocytes/macrophages (TEMs) are a myeloid cell subset known to be highly angiogenic in tumours. This study aimed to examine the kinetics of TEMs in patients wit...
متن کاملIdentification of proangiogenic TIE2-expressing monocytes (TEMs) in human peripheral blood and cancer.
Tumor-infiltrating myeloid cells, including tumor-associated macrophages (TAMs), have been implicated in tumor progression. We recently described a lineage of mouse monocytes characterized by expression of the Tie2 angiopoietin receptor and required for the vascularization and growth of several tumor models. Here, we report that TIE2 expression in human blood identifies a subset of monocytes di...
متن کاملIn vitro differentiation of human monocytes. Monocytes cultured on glass are cytotoxic to tumor cells but monocytes cultured on collagen are not
Cultivation of human blood monocytes on glass gives rise to cells nonspecifically cytotoxic to tumor cells. If the monocytes are cultured on collagen gels with no contact with glass, no such cytotoxic activity is induced. Killing appeared to be extracellular and probably contact dependent. The glass-induced cytotoxic activity was not related to protein content or cell viability. Rather, it appe...
متن کاملRegulation by Hypoxia and Angiopoietin-2 Tie2-Expressing Monocytes and Tumor Angiogenesis:
Recent findings indicate that tumor-associated macrophages are important drivers of tumor angiogenesis. Here, we review the essential role played by Tie2-expressing monocytes (TEM) in this phenomenon. TEMs are present in human blood and tumors and their elimination in various tumor models suppresses tumor angiogenesis. A ligand for Tie2, angiopoietin-2 (Ang-2), is produced by angiogenic tumor v...
