Zebrafish study confirms regenerated photoreceptor cells fully restore vision

Zebrafish photoreceptor cells stimulated with blue light show correct electrical activity. The picture was taken using the microscope that was custom-built for this study. Credit: Michael Brand and Evelyn Abraham Blinding diseases lead to permanent vision loss by damaging photoreceptor cells, which humans cannot naturally regenerate. While researchers are working on new methods to replace or regenerate these cells, the crucial question is whether these regenerated photoreceptors can fully restore vision. Now, a team of researchers led by Prof. Michael Brand at the Center for Regenerative Therapies Dresden (CRTD) of Dresden University of Technology has made an important step forward. Read More
