Microfluidic platform for the simultaneous generation of four independent gradients: towards the high throughput screening of trace elements for bone tissue engineering

We propose a microfluidics-based cell-culture platform for the screening of trace elements in bone tissue engineering. With this platform, it is possible to create four stable, independent and perpendicular diffusion-based concentration gradients in a single square chamber, in which cells are cultured. This allows examining the combined effect of four compounds in a single assay.
