Abstract

In contrast to the extensive evidence from animal studies, only few human data are available on the relation of vascular growth factors and collateral function as well as on the conditions which may modify their release or function. In 31 patients with total coronary occlusion (TCOs) blood was collected from distal to the occlusion site (collateral circulation) and from the aortic root (systemic circulation). Serum was used to assess its mitogenic potential in [³H]-thymidine incorporation assay on human umbilical vein endothelial cells. Serum from patients with the duration of occlusion between 1 and 3 months was significantly more mitogenic as compared to either shorter or longer duration of occlusion. None of the demographic or clinical factors correlated with the mitogenic activity of serum. Serum from patients with TCOs shows a particular time-dependent mitogenic profile with a maximal activity between 1 and 3 months following the occlusion. This profile corresponds to the experimentally described time-line of strongest collateral development and indicates the time-window for possible modification.

期刊介绍： Angiogenesis, a renowned international journal, seeks to publish high-quality original articles and reviews on the cellular and molecular mechanisms governing angiogenesis in both normal and pathological conditions. By serving as a primary platform for swift communication within the field of angiogenesis research, this multidisciplinary journal showcases pioneering experimental studies utilizing molecular techniques, in vitro methods, animal models, and clinical investigations into angiogenic diseases. Furthermore, Angiogenesis sheds light on cutting-edge therapeutic strategies for promoting or inhibiting angiogenesis, while also highlighting fresh markers and techniques for disease diagnosis and prognosis.
