Abstract

In this study, we examined the effects of the methanolic extract(CL-ex) of Codonopsis lanceolata on the angiogenesis stimulated with basic fibroblast growth factor(bFGF) in vitro, using porcine pulmonary arterial endothelial cells(PPAECs). In addition, we investigated the endothelial functions involved in angiogenesis, such as proliferation, migration and secretion of matrix metalloproteinases(MMPs), using human umbilical vein endothelial cells(HUVECS). CL-ex inhibited FGF-induced sprout formation in vitro at concentrations of 0.1-100 ug/ml. Although CL-ex did not affect the proliferation of endothelial cells, CL-ex strongly inhibited the FGF-induced migration of HUVECS at concentrations of 0.1-1 ug/ml; the degree of inhibition of endothelial cells by C-ex was 49.4% at 0.1 ug/ml and 71.9 % at 1.0 ug/ml. Moreover, CL-ex inhibited the secretion of MMPs from HUVECS stimulated with FGF. Therefore, the inhibitory effect of CL-ex on angiogenesis in vitro could be explained by the inhibition of endothelial cell migration. From these results, we suggest that Codonopsis lanceolata is a useful herb for the development of therapeutics or preventive food factors for angiogenesis related diseases, such as tumors.

더덕의 메탄올 추출물(CL-ex)이 혈관신생에 영향을 주는 지의 여부를 알아보기 위하여, 인간태반 정맥내피세포와 돼지 폐동맥내피세포를 이용하여 실험하였다. 실험 결과, 더덕추출물은 FGF에 의해 유도된 시험관 내 혈관신생을 억제하였다. 또한 더덕추출물은 내피세포의 DNA 합성에는 영향을 주지 않았으나, FGF에 의해 증가된 내피세포의 이동을 농도 의존적으로 강하게 억제하였고, MMPs의 분비 역시 감소시켰다. 이러한 결과에 의하면, 더덕에 함유된 혈관신생 억제 물질은 혈관내피세포의 이동 과정에 작용하여 그 효과를 나타내는 것이라 추정된다. 따라서 더덕은 그 발생과 진행이 혈관신생에 의존하고 있는 것으로 알려진 암 등의 질병 예방과 치료를 위한 유용한 식물자원으로 개발될 수 있음을 시사한다.
