The fact this worked on Type 1, which is an autoimmune disorder, is very interesting/surprising as a layman.
The patient was on immunosuppressants.
Amazing! Hopefully the effects are sustained over the long term and can be replicated.
The potential of the stem cell space is incredible. Another interesting development is patients "cured" of HIV following stem cell transplants to treat leukaemia - which has no direct clinical implications given the significant risk of stem cell transplant but does inspire hope for the future [1].

TFA claims the stem cells were administered into the abdominal muscles, which may reduce the "significant risk of stem cell transplant" compared to direct injection into the liver.
