Figure : Custom nylon mesh used to allow perfusion studies in a microfluidic chip. We show an schematic image of the nylon mesh used and a T 1 -FLASH sagittal images of the 4-well chip used containing the scaffolds at the bottom (water signal from the scaffold) before (top) and after (bottom) injecting water. We highlighted the well region with dashed green lines and the one with meshes in pink.
