Abstract
The shift from 2D cultures to 3D cultures enables improvement in cell culture research due to better mimicking of in vivo cell behavior and environmental conditions. Different cell lines and applications require altered 3D constructs. The automation of the manufacturing and screening processes can advance the charge stability, quality, repeatability, and precision. In this study we integrated the automated production of three 3D cell constructs (alginate beads, spheroid cultures, pellet cultures) using the Biomek Cell Workstation and compared them with the traditional manual methods and their consequent bioscreening processes (proliferation, toxicity; days 14 and 35) using a high-throughput screening system. Moreover, the possible influence of antibiotics (penicillin/streptomycin) on the production and screening processes was investigated. The cytotoxicity of automatically produced 3D cell cultures (with and without antibiotics) was mainly decreased. The proliferation showed mainly similar or increased results for the automatically produced 3D constructs. We concluded that the traditional manual methods can be replaced by the automated processes. Furthermore, the formation, cultivation, and screenings can be performed without antibiotics to prevent possible effects.
