Abstract
Additive manufacturing (3D printing) has been deployed across multiple platforms to fabricate bioengineered tissues. We demonstrate the use of a Thermal Inkjet Pipette System (TIPS) for targeted delivery of cells onto manufactured substrates to design bio-bandages. Two cell lines - HEK 293 (kidney) and K7M2wt (bone) - were applied using TIPS. We demonstrate a novel means for targeted cell delivery to a hydrogel support structure. These cell/support constructs (bio-bandages) had a high viability for survival and growth over extended periods. Combining a flexible biosupport with application of cells via TIPS printing now for the first time allows for custom cell substrate constructs with various densities to be deployed for regenerative medicine applications.
