London woman off insulin for Type 1 diabetes after a single dose of experimental manufactured stem cells

But there’s a tradeoff. The patients, however, require immune-suppressing drugs for life, so that the immune system doesn’t destroy the cells.

That was my question on reading the headline. Type 1 diabetes is an immune disorder, what they did here is replace the cells that had been killed by the immune system.

A second patient, according to the study, died of severe dementia.

Also, wtf. Why did they allow a patient with severe dementia into the study? If it's only a one or two year long study that person would have been displaying dementia already and likely couldn't actually consent to it
