Reactive jet impingement bioprinting of high cell density gels for bone microtissue fabrication.

abstract：:An important unsolved challenge in tissue engineering has been the inability to replicate the geometry and function of vascular networks and blood vessels. Here, we engineer a user-defined 3D microfluidic vascular channel using 3D printing-enabled hydrogel casting. First, a hollow L-shaped channel is developed using a...
