I was reading this news artical
and they were injecting human stem cells into mice with broken spinal cords.
and after 4 months, the mice could walk again.
now this has been done before, but no one was sure if the stemcells were the fix
or did they just start the healing process.
well they figuared out a well to tell.
inject the mice with a special toxin that only kill human cells.
well after that the mice couldn't walk anymore. the cells were indeed human cells.
hmm to have a job where you break the backs of mice, fix them, and then take it all away....
where do people find jobs like these, anyways?
