Scientists regenerate neurons that restore walking in mice after paralysis from spinal cord injury::In a new study in mice, a team of researchers from UCLA, the Swiss Federal Institute of Technology, and Harvard University have uncovered a crucial component for restoring functional activity after spinal cord injury. The neuroscientists have shown that re-growing specific neurons back to their natural target regions led to recovery, while random regrowth was not effective.
It does make you wonder what caused spinal injury in these mice. I do not suppose there is a sufficient natural supply of these kinds of injured mice.
But, if not animal testing, how do you propose to develop the treatment?
It’s a little grim, but there’s a standard SCI (spinal cord injury) guillotine that drops a weight with an angled wedge to cause a near perfectly replicable SCI. The mouse is sedated, but it’s not exactly a good time for the mouse.
But yeah, the alternative is testing on humans, which, I really don’t think we need a reminder on why that’s super illegal.
This is a remarkably specific and disturbing fact. Thank you for sharing.
