Abstract

To demonstrate a radiation effect on vasculature, we designed 3D in vitro micro vascular system. We used soft-lithography method to fabricate in vitro microfluidic chip which was composed of two media channels and three gel channels. We cultured human umbilical vein endothelial cells(HUVECs) to make vasculature. To form a vasculature, fibrin gel was used as extracellular matrix to support HUVECs. After embedding, HUVECs were exposed to radiation on day 0 or 4. After irradiation, we analyzed structure of vasculature and measured gene expression. The results demonstrate a difference radioresistance between early stage of vasculature and mature stage of vasculature.
