Makes way more sense timing wise, particularly in light of NICE publication date set currently for May 2019, and I just found the same Advent production scientist literally within seconds before you posted. Funny.
I keep seeing key pieces if my due diligence popping up in seemingly unrelated ways such as in this profile of the person hired for this position. Key topics being "producing mesenchymal stem cells and mononuclear cells" and "..regenerative treatment in patients with accute myocardial infarction." This is no coincidence as many will one day come to realize. Best wishes.
