After much hope and controversy, for the first time stem cells have proven to have the ability to cure blindness.
The news comes from a study on age-related macular degeneration (AMD) of the retina, the most common cause of blindness in individuals over the age of 50.
The Sunday Times reports that the treatment was developed by a group of British researchers, who say that in the next six to seven years the treatment will become a routine operation, which will not last more than an hour.
The treatment involves the replacement of a layer of degenerated cells with new cells created
In the next three to four years, it would be possible to do DNA sequencing in just 15 minutes and design tailor-made medicines for patients, Dr Mohan Rao, director of Centre for Cellular and Molecular Biology (CCMB), asserted at the annual conference of AP Cardiology Society of India on Saturday.
Based on Pharmicogenetics — a study of genetic differences in metabolic pathways which can affect individual responses to drugs — these specialized drugs will be able to combat diseases while minimizing side effects, Rao said. “We are transiting to cell-based therapy from the current chemical-based therapy.
