It's been a while since I looked at this stuff so apologies for the rustiness Columbia trial paper: https://www.nejm.org/doi/full/10.1056/nejm200103083441002 https://www.nejm.org/doi/full/10.1056/nejm200103083441002 Tampa trial paper: https://pubmed.ncbi.nlm.nih.gov/12953276/ https://pubmed.ncbi.nlm.nih.gov/12953276/ Additionally, it looks like I totally missed at least one European program at Lund University (review paper: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5345652/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5345652/) I've heard rumblings re preclinical prep work w/ the Takashi group at Kyoto University as well, not sure where that's at at the moment. I randomly found this review, but haven't had a chance to plough thru it yet, but I wouldn't be surprised that the stem cell tech these days makes whatever they used 20 years ago ancient and crude by comparison https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9890289/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9890289/
