Researchers develop a method of cross-linking enzymatic finely tuned for the adhesion of droplets of the inks and organic and extend the range of cell types that can be handled by bioprinting with a 3D printer to jet. Such an impression is very promising for regenerative medicine.
Re-printing of pieces of human body replacement may seem to be science fiction, but this technology is now becoming a reality. Before any real application, however, the bioprinting is still facing many technical challenges. Few methods currently exist to paste all cells from the droplets of bio-ink ” different because they do not work for each type of cell. This motivates new approaches.

This is only the beginning

Building on their previous work, the researchers from the Osaka University have now refined an approach based on enzymes for paste together of different cells from droplets of inks different living. “The impression of any tissue structure is a complex process,” says the lead author Shinji Sakai. “The bio-ink must have a viscosity sufficiently low to pass through the ink jet printer while quickly forming a structure in gel very viscous “.
Now, we need new scaffolds to be able to print and support these cells in order to bring us closer to 3D printing a complete functional tissues.

The new approach based on the cross-linking enzyme is very versatile and should help all the working groups to achieve this goal.
