Stem cells

Stem cells are a special type of cell, which under the right conditions can be encouraged to grow into any other type of cell in the body, including retinal cells (rods, cones and retinal pigment epithelial cells).

Electrical stimulation therapy

Electrical stimulation is under investigation to determine whether a small electric charge applied to the retina can stimulate the production of a number of important biological ‘factors’ that in turn could trigger light-sensitive cells (photoreceptors) to regenerate.

Growth factors

Growth factors are substances that promote the health and function of cells and tissues in the body.
