Macrophages can act as potent effector cells of the immune response. Cytokine signals generated during an immune response activate macrophages in a complex cascade of events. Activated macrophages are qualitatively different from mature resident tissue macrophages and from immature inflammatory macrophages.

This unit describes the isolation of murine macrophages from the peritoneal cavity under inflammatory and noninflammatory conditions. To investigate macrophage activation using a more homogeneous population of cells, macrophages derived from immature progenitor cells in bone marrow can be studied.

Angiogenesis, the process of new capillary formation from pre-existing vessels, has been established as an important mechanism involved in pathologic processes, such as cancer, as well as in normal physiology (Ribatti, D.; Vacca, A.; Roncali, L.
View Article and Find Full Text PDFPurpose: Current combination treatment strategies in malignancy are designed to evaluate the use of cytotoxic drugs and antiangiogenic agents. Endostatin, a fragment of collagen XVIII, specifically inhibits proliferation, migration, and differentiation of endothelial cells in vitro as well as angiogenesis and tumor progression in in vivo models. In this study, we determine the antitumor effect of rhEndostatin administered alone or in combination with Adriamycin against established orthotopic murine mammary carcinoma.
