In November 2010, Advanced Stem Cell Technology in Massachusetts was approved to conduct a human study in patent's with Stargardt's!! What fabulous news!!
From my research, they will be using embryonic stem cells, which are stem cells from embryos from a fertilized egg in vitro - so these eggs are fertilized in a lab and not in a woman's body.
The following website is an article outlining the study:
US starts human blindness trial using stem cells
Let's keep our fingers crossed and hope all goes well in this trial. Hopefully in the near future we will all be able to be treated!
