Before new treatments can reach patients, they must be tested in clinical trials. This is our second brief update on some stem-cell-related trials currently under way or recently approved.

What's covered in this update?

This update looks at trials for amyotrophic lateral sclerosis (ALS) or motor neurone disease, as well as the latest news on how the trials we told you about in September are progressing. We’ve included details of one or two new trials for some of the conditions we focussed on last time: spinal injury, Stargardt’s macular dystrophy and stroke. We’ll post more updates on other themes in future, so tell us if there’s an area you really want to know about.
