GoKawiilStanford team achieves deepest-yet integration of human brain tissue in mice
Researchers led by Sergiu Pașca at Stanford transplanted lab-grown human brain tissue into newborn mice missing part of their brains, and the tissue expanded to fill much of that space while forming functional connections with the host nervous system. Published in Nature on September 16, the study represents the most extensive fusion of human neural tissue into a living animal achieved to date, though behavioral tests showed the mice did not gain enhanced cognitive abilities.
