A bioink made from human platelet derivatives and plant-based cellulose nanocrystals (CNCs) can form 3D printed structures with exceptional cell-sustaining properties.

 .

Researchers at the 3B’s Research Group at the University of Minho, and the University of Oklahoma, report that stem cells encapsulated in the new nanocomposite bioink during printing thrive and proliferate without the need for animal-derived serum supplements.

 .

The result points to a way of producing highly biocompatible, “xeno-free” artificial tissues for medical or research purposes.

 .

Currently, a wide range of techniques and bioinks are being applied to the goal of 3D-printing artificial tissues and organs. Although each approach differs in terms of the deposition method and the mix of cells, biomaterial and bioactive molecules that compose the bioink, […]
