Abstract
In the fermented soybean product known as chungkookjang, diverse bioactive compounds are produced when the soybean proteins are degraded during fermentation. Vascular endothelial cells (EC) are crucial in vein function and the formation of new vessels. A treatment to stimulate formation of new blood vessels is needed in cerebrovascular diseases that lead to ischaemic stroke and heart attack, as well as for diabetic ulcers. VEGF (Vascular Endothelial Growth Factor) simulates EC formation. The effect of Chungkookjang ethanol extract (CEE) on the proliferation of EC was studied. CEE (100, 1000 μg/ml) and boiled CEE were as effective as VEGF (10 ng/ml) for the proliferation of human umbilical vascular endothelial cells (HUVEC). The effect of CEE on the migration of HUVEC was investigated using sprout analysis. CEE (100 μg/ml) was as effective as VEGF (10 ng/ml) for the migration of HUVEC. Isolation of specific peptides influencing the growth and migration of EC is needed.
