I fail to see how using cadaver tissue makes it invalid research. Verrain is happy to explain the work of The Wistar Institute and medical research in general with me. IIRC severl important cancer cell lines were taken from cadavers. Alloderm was certainly developed through research with cadaver tissue, considering the fact the product is made from cadaver tissue.
Of course, since I can’t get the link to work, there’s the possibility that the man means corpses which have been dead so long that no viable cells could be extracted. This would be an entirely different matter.
I believe Smith would remind us that Animals are beneath us. But that even the Lords of the Instrumentality are pleased to render honor to the Scanners.
