Screen Printing a Retina Organoid (IMAGE) NIH/National Eye Institute Caption Lavik's team proposed using a method to screen print tissue models. The idea is to create layers of the various types of retinal neurons that can be derived in a lab from adult stem cells. The method would allow the layers to be correctly oriented to mimic the structure of the human retina. Credit Erin Lavik, Sc.D.
