Lasers and Stem Cells Join Forces to 3D-Bioprint Organs

Posted by maxi@stemsave.com on Aug 28, 2019 4:05:00 PM

 

assets.newatlasA research team at the Netherlands’ Utrecht University, in collaboration with the Swiss EMPA Research Institute, have developed a new 3D bio-printer that significantly decreases printing times, without harming or damaging the cells being printed. Conventional bioprinting takes hours, and even days for some complex structures, which creates the problem of maintaining the live cells in the structure that is printed over a prolonged period. The technique involves using a laser beam aimed at a printer that is depositing a light-sensitive hydrogel that contains stem cells. The laser can precisely target a structure within the gel and solidify it within seconds, without affecting the contained stem cells.

This technique has already allowed researchers to print structures of several square centimeters in size, some of these structures being heart valves, a meniscus and even a complex femur bone. Additionally, the researchers are now adding endothelial cells into the mix, since these are the cells that line the inside of organs and blood vessels. Using this technique, researchers can soon overcome the biggest hurdle in effective 3D bioprinting: the lengthy printing process that causes the printed cells to necrose.

This innovative research demonstrates the integral role stem cells are playing in cutting edge medical care options. By banking their own valuable stem cells, families can ensure that they will have access to these emerging therapies soon.
