RETINITIS PIGMENTOSA (AT A GLANCE)

1 Jul 2017 Uncategorized

Retinitis pigmentosa (RP) is a clinically and genetically heterogeneous group of inherited retinal disorders characterized by diffuse progressive dysfunction of predominantly rod photoreceptors, with subsequent degeneration of cone photoreceptors, and retinal pigment epithelium (RPE).

CURE FOR BLINDNESS ; A MAJOR BREAKTHROUGH

1 Jul 2017 Uncategorized

The researchers at the University of Cambridge, Britain, had a Major Breakthrough and taken it a step further by printing eye cells — making it the first time 3D printing technology is used to create mature central nervous system cells.

Experts at the University of Cambridge used inkjet printing technology to produce artificial tissue grafts made from a variety of cells found in the human retina.

Published in the journal IOP Science, the researchers printed two types of central nervous system cells using a piezoelectric inkjet printer; the Ganglion cells (which transmit information from the eye to the brain) and Glial cells(which provide protection and support for neurons), from the retina of adult rats.This 3D printer ejects cells through a sub-millimeter diameter nozzle when an electric pulse is applied, the printed cells were able to grow normally, remained healthy and retained their ability to survive and grow in culture.
