The world's first patient transplanted donor cells in the retina
According to the publication The Japan Times, a group of Japanese scientists from the Institute of Physical and Chemical Research Riken, which is located in Waco, it was possible the world's first transplant patient with age-macular degeneration of retinal cells, grown from donor pluripotent cells of the recipient. The uniqueness of the transaction consists in the fact that only by using patient's own tissue such interventions carried out previously.
Age-related macular degeneration (AMD) is a disease that affects the central retina Department - macula. Macula plays a key role in the formation of. Age-related macular degeneration - a very common cause of visual loss in people over 60 years. Since only the central vision is affected, people rarely completely lose the ability to see, but if AMD can be difficult to read, drive a car or do other work that needs to distinguish fine details. The risk of AMD increases with age to 75 years reaches almost 30%. As already mentioned, before transplant performed only using autograft (using the patient's own tissue), but the use of donor cells grown in a special medium, much more advantageous both in economic terms and in terms of time: The operation is much cheaper and requires a fraction of the time. The first patient, which used a new technology, became a resident of Japan over 60 years. The operation took about an hour: at this time in the right eye of a patient placed 0, 05 milliliters of fluid containing about 250,000 donor cells. Preliminary data indicate that the operation went well and was a success, but you can celebrate bude only a few years. Now in the course of the year the patient will be monitored by doctors, and over the next three years, waiting for his regular check-ups.
