Increasing the viability of bio-printing 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. For example, printing techniques need to be developed which are both controllable and less harmful to the process of preserving human cell tissue viability and functions.
