Microfluidic devices can sort viable mammalian cells by size. In this study, we investigated size-based sorting of cells using flow splitting microfluidic devices based on hydrodynamic filtration for noninvasive cell cycle synchronization. Two different types of mammalian cell lines, HepG2 (human hepatocellular liver carcinoma cell line) and NIH/3T3 (mouse embryonic fibroblast cell line) were sorted by microfluidic device and its DNA contents were analyzed. Our results showed that a microfluidic device can synchronize the cell cycle after size separation. The damage-free separation of living cells in different phases of the cell cycle represents a potentially promising technology for the investigation of gene transfection and gene expression.
