Angiogenesis|Angiogenese|血管新生

血管新生(英文:Angiogenesis)是一个生理上新的微血管發展成一個血流供應系統的過程。而 Vasculogenesis通常指自發性的血管形成,另外Intussusception則是指較一般快速形成的血管新生過程。这一过程在人体生长与发育,及伤口癒合中常见。另外,血管新生是肿瘤恶化过程中的重要步骤。

血管新生在於生長或是發育上扮演重要的角色,例如在傷口癒合、女性經期、胎兒生長發育。而在腫瘤生長上,血管新生則會是腫瘤從休眠期轉變成惡性、生長迅速、可能侵襲其他組織的關鍵。而相較於癌症的研究,血管新生也在斷肢接合、心肌梗塞、腦中風、老人退化性黃斑等病症上佔有很重要的地位。

Angiogenesis is the physiological process involving the growth of new blood vessels from pre-existing vessels. Though there has been some debate over terminology, vasculogenesis is the term used for spontaneous blood-vessel formation, and intussusception is the term for new blood vessel formation by splitting off existing ones.

Angiogenesis is a normal and vital process in growth and development, as well as in wound healing. However, it is also a fundamental step in the transition of tumors from a dormant state to a malignant one. The identification of an angiogenic diffusible factor derived from tumors was made initially by Greenblatt and Shubik in 1968.

Als Angiogenese (griechisch ἄγγος [ˈaŋ ɔs] „Gefäß“ und γένεσις [ˈgɛnezɪs] „Entstehung“) bezeichnet man das Wachstum von kleinen Blutgefäßen (Kapillaren), überwiegend durch Sprossung aus einem vorgebildeten Kapillarsystem. Hiervon zu unterscheiden ist die Neubildung von Blutgefäßen aus den sogenannten Endothelialen Vorläuferzellen, welche als Vaskulogenese bezeichnet wird.
