The levels of NO, VEGF, and GM-CSF secreted by cultured EPCs. (a) The level of NO produced by cultured EPCs of the normotriglyceridemic and hypertriglyceridemic men groups was remarkably lower than that of the premenopausal women groups. Besides, the secretion of NO from hypertriglyceridemic men was statically elevated compared with that from normotriglyceridemic men. Nevertheless, the level of NO in the EPCs cultural media of the hypertriglyceridemic premenopausal women was not significantly different from that of the normotriglyceridemic premenopausal women). (b) and (c) There was no obvious difference in VEGF or GM-CSF secretion between four groups.
