Abstract
Various cell stimulation experiments have been traditionally conducted regarding observation of cells to specific stimulative factors, and in light of this area of study, we report a new method by utilizing micro-beads. HeLa cells and MC3T3 cells are cultured in straight PDMS (polydimethylsiloxane) microfluidic devices and are stimulated by sterilized polystyrene micro-beads. Cell culture medium either with or without micro-beads are introduced in microfluidic cell culturing chambers at a specific time interval, and stimulated cells are observed using an inverted microscope. The results show that cells exposed under micro-bead stimulation perform at a higher growth rate than those under normal conditions. This paper demonstrates that micro-beads can be used as a physical stimulation factor and affect cell growth behaviors.
