3-D bioprinting is a highly-advanced manufacturing platform that allows for the printing of tissue, and eventually vital organs, from cells. This could open a new world of possibilities for the medical field, while directly benefiting patients who need replacement organs.

Instead of waiting for a suitable donor or having the risk of their body rejecting a transplanted organ, 3-D printed organs allow patients to have a customised organ fabricated specifically to replace their faulty ones. However, even with headway that 3-D bioprinting has made in the last two decades, it is still lacking significant strides in order to produce complex 3-D biomimetic tissue constructs.

According to researchers from the Singapore University of Technology and Design (SUTD), Nanyang Technological University (NTU) and Asia University, tissue culture techniques in particular require accelerated progress to address the bottleneck of maturing bioprinted multicellular 3-D tissue constructs into functional tissues. Their research paper, titled "Print me an organ! Why are we not there yet?" has been published in the Progress in Polymer Science.

In the paper, the researchers also provide in-depth review of recent improvements and analyse the bioprinting techniques, progress in bio-ink development, and implementation of new bioprinting and tissue maturation strategies. Special attention was also given to the role of polymer science and...
