Innovative Cell Printing Technologies Hold Promise For Tissue Engineering R&D

March 29, 2012

A novel method for printing human cells onto surfaces in defined patterns can help advance research on tissue engineering and regeneration, as described in an article in Tissue Engineering, Part C, Methods, a peer-reviewed journal from Mary Ann Liebert, Inc (http://www.liebertpub.com).

“Cell printing is one of the breakthrough technologies that will make the application of stem cells for tissue engineering feasible,” says John Jansen, DDS, PhD, Methods Co-Editor-in-Chief and Professor and Chairman, Department of Biomaterials, Radboud University Nijmegen Medical Center, The Netherlands.

Yu Fang and colleagues, University of Michigan, Ann Arbor, combined two microscale techniques to dispense and position cells in a variety of patterns. They then demonstrated the ability to use these 3-dimensional cell systems to monitor cell signaling events known to have a role in the growth, proliferation, and metastasis of cancer cells. The authors describe the use of sound waves to deliver microdroplets of cells and polymer-based phase separation to control cell placement in the article “Rapid Generation of Multiplexed Cell Co-Cultures Using Acoustic Droplet Ejection Followed by Aqueous Two-phase Exclusion Patterning.” (http://online.liebertpub.com/doi/abs/10.1089/ten.TEC.2011.0709)
