Video- A deeper view of eye diseases with bioprinted tissue
“National Institutes of Health and University of Amsterdam researchers successfully printed a combination of cells that form the outer blood-retina barrier, which supports the retina’s light-sensing photoreceptors, to aid in the study of these diseases. Different cell types primarily derived from patient stem cells were embedded in a hydrogel carrier, which was then printed on a biodegradable scaffold. The cells began to mature into a dense capillary network. Growth of blood vessels across printed rows of the 3D-printed cell mixture. By day 7, blood vessels fill in the space between the rows, forming a network of capillaries.” MORE WITH VIDEO
