Design and manufacture of 3D cell culture plate for mass production of cell-spheroids

Abstract

Abstract A 3D cell culture is preferred to 2D cell culture since it allows cells to grow in all directions in vitro, similar to how they would in vivo. 3D cell culture plates currently used in tissue engineering research have limited access to control the geometry. Furthermore, 3D cell culture plate manufacturing methods are relatively complex, time-consuming, labor-intensive, and expensive. Therefore, a design and manufacturing method, which has relatively low cost, high throughput, and high size flexibility, is proposed. Cell culture plate was fabricated by computer aided design and manufacturing software using polydimethylsiloxane as a plate constituent. With the successfully-developed 3D cell culture plate, the morphology and viability of the cultured mesenchymal stem cells were tested.The mesenchymal stem cells seeded on the newly-fabricated 3D cell culture plate aggregated to form 3D spheroids within 24 h of incubation and well-maintained their viability. Thus, due to the capacity of mass production of the cell spheroids with a desired cell viability, the newly-fabricated plate has a great promise to prepare 3D cell spheroids for experimental as well as clinical applications.
