title: Development of a novel automated cell isolation, expansion, and characterization platform.
abstract: Implementation of regenerative medicine in the clinical setting requires not only biological inventions, but also the development of reproducible and safe method for cell isolation and expansion. As the currently used manual techniques do not fulfill these requirements, there is a clear need to develop an adequate robotic platform for automated, large-scale production of cells or cell-based products. Here, we demonstrate an automated liquid-handling cell-culture platform that can be used to isolate, expand, and characterize human primary cells (e.g., from intervertebral disc tissue) with results that are comparable to the manual procedure. Specifically, no differences could be observed for cell yield, viability, aggregation rate, growth rate, and phenotype. Importantly, all steps-from the enzymatic isolation of cells through the biopsy to the final quality control-can be performed completely by the automated system because of novel tools that were incorporated into the platform. This automated cell-culture platform can therefore replace entirely manual processes in areas that require high throughput while maintaining stability and safety, such as clinical or industrial settings.
