So in the first-case scenario, we re-implanted the cells in the normal brain and what we saw is that they completely disappeared after a few weeks, as if they were taken from the brain, they go back home, the space is already busy, they are not needed there, so they disappear.
Portanto, no primeiro cenário, reimplantámos as células no cérebro normal e vimos que elas desapareceram  completamente passadas umas semanas, como se tivessem sido  retiradas do cérebro, regressassem a casa, o espaço já está ocupado, não são necessárias, desaparecem.
