3D printing performances developed at the Oxford University will help regenerative medicine


An interdisciplinary  team from the Department of Chemistry and the Department of Physiology, Anatomy and  Genetics at Oxford and the Centre for Molecular Medicine at Bristol, demonstrated how a  range of human and animal cells can be printed into high-resolution tissue constructs. Led  by Professor Hagan Bayley, the team found a way to produce tissues in self-contained cells that support the structures to keep their shape.


Technically, the cells were contained  within protective nanolitre droplets wrapped in a lipid coating that could be assembled,  layer-by-layer, into living structures. Once fully grown, the patterned cellular  constructs mimic or potentially enhance natural tissues. ‘We were aiming to fabricate  three-dimensional living tissues that could display the basic behaviors and physiology  found in natural organisms. (…) We focused on designing a high-resolution cell printing  platform, from relatively inexpensive components, that could be used to reproducibly  produce artificial tissues with appropriate complexity from a range of cells including  stem cells,” Dr Alexander Graham, lead author, revealed in research published in the  journal Scientific Reports. Probably the most important application of the method will be  to create personalized treatments by using cells sourced from patients.
