It's been lurking out there for many years, raising hopes for that miracle cure for paralysis only to crush them time after time.  The elusive cure for paralysis has posed a significant challenge for scientists and it has multiplied even further when it's involved the use of stem cells, in particular for paralysis caused by a spinal cord injury or disorder.

We've been following The Miracle Cell project produced by the San Francisco Chronicle.  The first two of a four-part investigative series included:
In search of a miracle
Merchants of hope

Part three is Immense promise, hard-won progress which takes a deep dive into the difficulties science experiences in order to demonstrate the viability of stem cell therapy.  Good reading if you want to understand the A to Z of stem cell research.
