The stories told in this series have been astonishing, and the exciting implications for medicine are wonderful.
This concluding part features toddler Adam, who was diagnosed with a severe form of brittle bone disease after an ultrasound revealed problems with his legs.
An experimental stem-cell treatment was performed on the unborn Adam – and it gave him a much brighter future.
We also meet Emily, whose brain was attacked by her own immune system, and a father who gave up his job to raise money for research into his sons’ ultra-rare genetic disease.
Inspiring stories, filled with hope.
