New insight into eye diseases

Many diseases that lead to blindness, such as glaucoma and macular degeneration, are caused by the death of certain cells in the human retina that lack the ability to regenerate. But in species such as zebrafish these cells, known as Muller glial cells (MGs), do serve as retinal stem cells that are capable of generating new cells. In a new study, a research team investigated whether the regenerative power of cells in zebrafish could be recreated in mammals, specifically mice.
