Machine-Made “Skin”
October 30, 2012 | Terry Sharrer
Engineers and chemists at the University of Toronto have built a tissue culture device that can produce multiple layers resembling skin. Their machine uses hydrogel sheets on a drum roller where living cells are precisely placed. As the drum turns, more of the cell-embedded substrate is built up. Besides mimicking skin layers, the researchers suppose this could be a useful tool is making vascular patches and for drug testing. MORE
