Abstract:
In human body, the most common structures formed by epithelial cells are hollow cysts or tubules. The key feature of the cysts and tubules is the central lumen, which is lined by epithelial cell sheets. The central lumen allows material exchange, thus it is indispensable for the proper function of the epithelial tissue. In order to understand the way that the epithelial cells form highly specialized structure, an in vitro three-dimensional (3D) culture system was established. The Caco-2 cells were embedded in reconstituted basement membrane termed matrigel, whose biochemical constitution and
