Cone-rod dystrophy

Researchers find causative factors in retinal dystrophies

Scientists from the Florida campus of The Scripps Research Institute have discovered how a protein called α2δ4 establishes proper vision. Their research helps explain why mutations in the gene encoding α2δ4 lead to retinal dystrophy, a disease characterized by defective color vision and night blindness. To study how this protein supports vision, the researchers modeled

Stem-cell derived retina found to improve vision in monkeys with RP

Researchers at the RIKEN Institute in Japan have succeeded in growing human embryonic stem cell-derived retina (hESC-retina) and transplanting that tissue into the retinas of rhesus monkeys with Retinitis Pigmentosa (RP). Three weeks after the treatment, visual tests on two of the monkeys found their vision had improved. In the study, published in the journal PNAS,

Amniotic membrane derived stem cell transplants show benefit in retinal diseases

A team of researchers at the CHA University in South Korea has successfully transplanted mesenchymal stromal cells (MSCs) derived from human amniotic membranes of the placenta (AMSCs) into laboratory mice modeled with oxygen-induced retinopathy, which is used to simulate many retinal diseases. The treatment aimed at suppressing abnormal angiogenesis (blood vessel growth) which is recognized

UCI-led team begins first clinical trial of stem cell-based retinitis pigmentosa treatment

Participants are being enrolled in the first clinical trial that tests the use of retinal progenitor cells to treat retinitis pigmentosa. The product of stem cell research at UCI’s Gavin Herbert Eye Institute and Sue & Bill Gross Stem Cell Research Center, these retinal progenitors are similar to stem cells in terms of potential regenerative
