As we age, vision problems are unavoidable. Age-related macular degeneration breaks down a thin layer of cells in the back of your eye 鈥?the retinal pigment epithelium RPE 鈥?on the way to causing vision loss. Recently published research from the Neural Stem Cell Institute in Rensselaer, New York, shows the RPE to have some very interesting and unusual characteristics. Researchers discovered that the RPE is able to self-regenerate in vivo and act as stem cells 鈥?differentiating into nerve, cartilage, and bone cells when grown in the correct medium. But that not the best part of the report stanley cup the RPE is available for extraction from the recently deceased, and from living donors, making available a vast supply of stem cells without any ethical entanglements. Let take a look at the RPE and it function within the eye along with how a set of researchers stumbled on this set of life giving characteristics. Top image from Masca_Riden/Deviant Art. What does the retinal pigment epithelium do The retinal pigment epithelium RPE is a thin layer of cells that acts as a support system for the retina. You might have seen the RPE before and not noticed it 鈥?the RPE is black in color against the rest of a dissected cow eye. The RPE shields the retina from recei stanley polska ving too much light, and it also supplies glucose for energy and secretes a subst stanley tumblers ance that builds and maintains the retina.
