Latest Retinal pigment epithelium Stories
University of Kentucky researchers, led by Dr. Jayakrishna Ambati, have made an exciting finding in the "dry" form of age-related macular degeneration known as geographic atrophy (GA). GA is an untreatable condition that causes blindness in millions of individuals due to death of retinal pigmented epithelial cells. The paper, "ERK1/2 Activation is a Therapeutic Target in Age-Related Macular Degeneration" appears in the current online issue of the premier journal Proceedings of the National...
Study shows grapes provided more antioxidant protection for eyes than lutein Can eating grapes slow or help prevent the onset of age-related macular degeneration (AMD), a debilitating condition affecting millions of elderly people worldwide? Results from a new study published in Free Radical Biology and Medicine suggest this might be the case. The antioxidant actions of grapes are believed to be responsible for these protective effects. The study compared the impact of an...
Short interfering RNAs induce retinal degeneration via TLR3 and IRF3 According to new research by University of Kentucky investigators, an emerging pharmaceutical platform used in treating a variety of diseases may produce unintended and undesirable effects on eye function. The paper, "Short-interfering RNAs Induce Retinal Degeneration via TLR3 and IRF3", appears in the current online edition of the journal Molecular Therapy, a publication of the Nature Publishing Group and the American...
MARLBOROUGH, Mass., June 16, 2011 /PRNewswire/ -- Advanced Cell Technology, Inc. ("ACT"; OTCBB: ACTC), a leader in the field of regenerative medicine, announced today the enrollment of the first patients in its two Phase 1/2 clinical trials for Stargardt's Macular Dystrophy (SMD) and Dry Age-Related Macular Degeneration (Dry AMD) using retinal pigment epithelial (RPE) cells derived from human embryonic stem cells (hESCs). The patients were enrolled at the Jules Stein Eye Institute at the...
MARLBOROUGH, Mass., May 16, 2011 /PRNewswire/ -- Advanced Cell Technology, Inc. ("ACT"; OTCBB: ACTC), a leader in the field of regenerative medicine, announced today that the Casey Eye Institute (CEI) at Oregon Health & Science University (OHSU) in Portland, Ore., has received institutional review board (IRB) approval to be a site for its Phase 1/2 human clinical trial for Stargardt's Macular Dystrophy (SMD) using retinal pigment epithelial (RPE) cells derived from human embryonic stem...
The notion of transplanting adult stem cells to treat or even cure age-related macular degeneration has taken a significant step toward becoming a reality. In a study published today in Stem Cells, Georgetown University Medical Center researchers have demonstrated, for the first time, the ability to create retinal cells derived from human-induced pluripotent stem cells that mimic the eye cells that die and cause loss of sight.Age-related macular degeneration (AMD) is a leading cause of visual...
MARLBOROUGH, Mass., March 23, 2011 /PRNewswire/ -- Advanced Cell Technology, Inc. ("ACT"; OTC Bulletin Board: ACTC), a leader in the field of regenerative medicine, announced today that China's State Intellectual Property Office (SIPO) has allowed the Company's patent application to provide broad intellectual property protection in China for the manufacturing and pharmaceutical preparations of retinal pigment epithelial (RPE) cells from human embryonic stem cells (hESCs). This Chinese...
Research lead by Dr. Nicolas Bazan, Boyd Professor and Director of the Neuroscience Center of Excellence at LSU Health Sciences Center New Orleans, identifying an enzyme that makes neuroprotectin D1 which specifically and selectively protects retinal cells key for vision, will be published in the June 26, 2009 issue of the Journal of Biological Chemistry.Dr. Bazan's research team previously discovered neuroprotectin D1 (NPD1), a naturally produced chemical messenger that protects cells from...
New Technique May Spot Evidence of Macular Degeneration Years EarlierA layer of "dark cells" in the retina that is responsible for maintaining the health of the light-sensing cells in our eyes has been imaged in a living retina for the first time.The ability to see this nearly invisible layer could help doctors identify the onset of many diseases of the eye long before a patient notices symptoms. The findings are reported today's issue of Investigative Ophthalmology and Visual...
By Hu, Dan-Ning Simon, John D; Sarna, Tadeusz ABSTRACT The mammalian eye consists of several layers of pigmented tissues that contain melanin. The eye is a unique organ for pigment cell research because one can isolate and compare melanosomes from different tissues and embryonic origins. Retinal, iris and ciliary pigment epithelial cells are derived from the neural ectoderm, more specifically from the extremity of the embryonic optical cup, which is also the origin of the retina. In contrast,...
