Summary: | The mature murine macrophage‐like cells NCTC‐3749 and J‐774, the Immature human macrophage‐like cells U‐937‐1, and their conditioned media exhibited potent angiogenic activity in rat corneas and stimulated proliferation of bovine aortic endothelial cells (BAEC) and DNA synthesis in BALB/C‐3T3 cells in culture. In contrast, the immature human macrophage‐like cells HL‐60 and their conditioned media either failed to produce or release detectable quantities of these activities. Exposure of HL‐60 cells to phorbol‐myristate‐acetate (PMA) did not enhance expression of angiogenic and growth stimulating activities by these cells. Both the angiogenic and growth stimulating activities appear to be mediated by a factor(s) that has biochemical properties in common with macrophage‐derived growth factor (MDGF) produced by normal rat peritoneal macrophages. These results suggest that NCTC‐3749, J‐774, and U‐937‐1 macrophage‐like cell lines may be a useful source for the large scale production and characterization of MDGF and macrophage‐derived angiogenic activity. |
