In research write this workweek , scientists report that they’vesuccessfully transplant human stem jail cell - gain neuron into the brains of living mice . That ’s right , we ’re talking about a functioning trans - species transplant of mental capacity matter . The researchers took human embryonic stem cadre , and grew them in a culture with black eye nerve cell that had a specific trait — they ’re activate by light . The prow - cell derived neurons do n’t commonly have this power , but progressively gained it when grown with the mouse neurons .
The stem - cell neuron were then implanted into a living shiner ’s hippocampus , where the graft were able-bodied to inversely interact with the mouse ’s neuronal mesh , and integrate into it . They became part of the meshing , and go normally .
While the whole “ transplanting into a black eye ” thing is very cool , it ’s not really why this work is important . The best part is that you may train neurons , and then successfully transpose them into a wit , giving us another avenue to facilitate treat those effectuate with Parkinsons and Alzheimers disease , stroke , and epilepsy .
