Restoring retina cells (i.e. that allow you to see) by turning on Muller cells in the retina to form new retinal cells....
Scientists have long been aware of Müller cells (which exist in great abundance in the eye)...In recent years, however, researchers have reported that these cells sometimes exhibit progenitor cell behavior ... Progenitor cells are similar to stem cells but are more mature and are more limited in the number of cells types they can become.
... In their study, Chen and her team observed that when the naturally occurring chemicals ... were injected into the eye, the Müller cells began to divide and proliferate....
In both cases, the cells became progenitor cells and then changed into retinal cells. And with aminoadipate, the newly minted retinal cells migrated to where they might be needed in the retina and turned into desirable cell types...the type of cells that are lost in retinitis pigmentosa or macular degeneration...
