Visualizing and Evaluating Cancer Cell Growth and Invasion by a Novel 3D Culture System

With the development of new materials and technologies, it is possible to access gene function and drug metabolism using a three-dimensional (3D) cell culture system, which is more suitable for mimicking the in vivo microenvironment of cultured tumor cells ex vivo. SeedEZ is a novel and versatile tool that allows culturing of different types of cells with user convenience and in a desired sequence. This system provides a bridge between traditional 2D culture and animal experiments. Here, we provide two examples demonstrating how to evaluate cancer cell growth by the SeedEZ 3D scaffold and cancer cell invasion by the SeedEZ 3D ring, in order to promote understanding of the necessity of this novel cell culture system.
