A research team from Utrecht University has successfully fabricated working livers using a newly developed ultrafast volumetric 3D bioprinting method.
By means of visible light tomography, the volumetric bioprinting method enabled the successful printing of miniature stem cell units by making the cells “transparent”, which meant they retained their resolution and ability to perform biological processes.
Printed in less than 20 seconds, the liver units were able to perform key toxin elimination processes mimicking those that natural livers perform in our bodies, and could open new opportunities for regenerative medicine and personalized drug testing.
