We investigated the effect of a hot water extract from Gardenia fruit (Gardenia jasminoides ELLIS) (GFE), which has a stimulatory effect on endothelial cell proliferation, on the proliferation of A10 cells, an established cell line of vascular smooth muscle cell from murine aorta in a culture system. GFE did not change the number of A10 cells after a 48 h culture. GFE significantly increased the incorporation of [^3H]thymidine and [^<14>C]leucine into the acid-soluble fraction of bovine aortic endothelial cell layers, but significantly decreased that of A10 cells. These results suggested that GFE stimulates the proliferation of endothelial cells but not of A10 cells. In the endothelial cell culture, GFE significantly increased the accumulation of basic fibroblast growth factor, which is an autocrine for endothelial cell proliferation in medium and low-affinity (glycosaminoglycans-binding) fractions, while A10 cells did not produce a significant amount of the factor. Since it is postulated that a selective stimulation of endothelial cell proliferation by increasing the production of basic fibroblast growth factor is appropriate for prevention of arteriosclerosis and thrombosis, GFE may contain a beneficial component as a useful drug.
