In this study, we developed a cell culture device using gelatin. An appropriate material was sought to be used as a mold for the gelatin gel, and the bonding method between the gelatin gel and the coverslip, which was the cell culture surface, was investigated. The developed device can be used with a high-magnification objective lens. Furthermore, we report that human vascular endothelial cells and fibroblasts were co-cultured in the gelatin device, and a capillary network was successfully constructed.
