Abstract

en

Summary: Background: New blood vessel development can be induced by supplementation with angiogenic growth factors. In some older diabetic or hypercholesterolaemic patients, however, endothelial cells are defective and cannot support angiogenesis.
Methods: Endothelial progenitor cells (EPC) can help to overcome this limitation, providing a source of viable endothelial cells.
Results: It has been demonstrated that EPC can improve neovascularization in ischaemic hind limb, accelerate blood flow in diabetic mice, and improve cardiac function.
Conclusions: In this review, we will summarize the effects of EPC in the treatment for experimental peripheral ischaemia.

Zusammenfassung: Grundlagen: Die Entwicklung neuer Blutgefäße kann durch die Gabe von angiogenetischen Wachstumsfaktoren induziert werden. Bei älteren Zuckerkranken oder Hypercholesterinämie-Patienten sind die Endothelzellen geschädigt und können die Angiogenese nicht unterstützen.
Methodik: Mit Hilfe der endothelialen Progenitorzellen (EPC) können funktionsfähige Endothelzellen gebildet werden.
Ergebnisse: Es konnte gezeigt werden, daß die EPC zu einer Neovaskularisation in ischämischen Extremitäten führt, den Blutfluß bei diabetischen Mäusen und die Herzfunktion verbessert.
Schlußfolgerungen: In diesem Review diskutieren wir die Effekte der EPC bei der Behandlung experimenteller peripherer Ischämien.
