    Seeing the Future: Zebrafish Regenerates Fully Functional Photoreceptor Cells and Restores its Vision

    September 2, 2024, Categories  Biology/Biotechnology, Health/Medical

    A microscopic image displaying a field of small, round shapes against a dark background. The shapes are predominantly green. Some shapes have magenta-colored spots or protrusions, creating a mixed pattern of green, white, and magenta. The image is overlaid with a rectangular inset, zooming in on a section of the shapes, where the same color patterns are visible, but in greater detail.
    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.

    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...
