Canadian doctors reverse severe MS using stem cells
Sounds like another good reason to consider banking stem cells, as described here: https://news.ycombinator.com/item?id=11830407In this case the article describes using chemotherapy to stimulate generation of stem cells, then scrubbing them of the disease before reintroducing.  I have no expertise in this field, but I would think having a bank of healthy stem cells would have simplified the procedure and perhaps improved the likelihood of positive outcomes.@markkat if you're reading this, do you have any comment?
