Missing a Few Brain Cells? Print New Ones!
Will Knight writes in NewScientist:
A printer that spits out ultra-fine droplets of cells instead of ink has been used to print live brain cells without causing them any apparent harm. The technique could open up the possibility of building replacement tissue cell by cell, giving doctors complete control over the tissue they graft.
The device is a variant of a conventional ink-jet printer. Instead of forcing individual droplets of ink through a needle-shaped nozzle and onto the page, the cell printer uses a powerful electric field to produce droplets just a few micrometres in diameter, far smaller than is achievable by other means.
