In addition to medicine, 3D bioprinting is essential for the production of cultivated meat tissue.

But the bioinks used have limitations that prevent proper flow of cells and just how structured together they can be printed.

Now, Korean scientists have used algae to make an alginate ink crosslinkable with visible light for higher cell viability.

And still useful for artificial organ production.

In addition to organ regeneration, research continues into the development of purely artificial replacement organs using printed biomaterials combined with cell tissue. But existing bioinks have had cytotoxicity issues.

Now, a Korea Institute team have developed a temperature sensitive hydrogel that induces growth factors and cellular regeneration and biodegrades afterwards.
