摘要：This paper describes a co-culture method using cell fiber technology. Cell fibers are cell-laden hydrogel microfibers, in which cells are cultured three-dimensionally and allowed to reach more mature state than the conventional two-dimensional cell culture. Cells in the cell fibers are encapsulated by alginate shell. Only cellular secretome is released into the surrounding environment through the shell while the cells were retained by the fiber. With their high handleability and retrievability, we propose to use the cell fibers for co-culture to ensure steady supply of cellular secretome. We cultured mouse C2C12 myoblasts with mouse 3T3 fibroblasts encapsulated in the cell fibers for two days. The number of C2C12 cells increased proportionally to the number of co-cultured 3T3 fibers, suggesting that the secretome of 3T3 fibers promoted survival and proliferation of C2C12 cells. We believe that cell fiber technology is a useful tool for co-culturing cells, and it will contribute to both basic cell biology and tissue engineering with its unique features.
