Miniature Valves Play Significant Role in Viability of 3D Bio-Printing of Human Cells

The rapid development of viable inkjet technology for highly specialised applications, such as printing human cells, continues to generate significant interest. If successful, the realisation of this technology for specialised biological applications, generally known as ‘biofabrication’, has the potential to replace the long established (and often controversial) process of using animals for testing new drugs. However, there are many challenges to overcome to enable the successful production of a valve-based cell printer for the formation of human embryonic stem cell spheroid aggregates.

New drugs can take more than 10 years to develop, and only around 16% of drug candidates that begin pre-clinical testing are approved for human use. This low success rate is partially due to the different responses of humans and the animal models currently used for testing. A key challenge in bioprinting has been the development of more gentle printing processes to preserve cellular functions. By encapsulating cells inside a gel, complex 3D structures can be printed with cells suspended throughout.
