Zebrafish exhibit this regeneration through their Müller glia (MG) cells, which act as stem cells. Upon retinal damage, MG cells re-enter the cell cycle, producing neuronal progenitors that ...

Study identifies a signaling cascade behind retina regeneration in zebrafish. ScienceDaily . Retrieved June 2, 2025 from www.sciencedaily.com / releases / 2022 / 12 / 221220112953.htm ...

Highlights: . Retinal degeneration causes progressive loss of vision and has no cure at present. Zebrafish possess mechanism to self-repair their retinas with restoration of vision.

These five images, spanning 28 days, show how regeneration happens in the zebrafish retina. Rods are shown in green, regenerating cells are shown in red, and all other cells are blue.

Zebrafish easily recover from retinal injuries that would permanently blind a person. Early studies in zebrafish led to the idea that dying retinal cells release signals that trigger support cells ...

A study of the retinal development of zebrafish larvae and the genetic switch it has identified may help understand the progression of disease and find more effective treatments for blindness.

Neurons in the zebrafish retina project into 10 areas in the brain known as AF regions; however, very little is known about the role of these regions.
