Tiny ‘ice printing’ sculptures could help scientists create blood vessels

Scientists are working to build blood vessels from human cells using tiny ice sculptures – these cool 3D shapes twist and branch like real arteries and can be used as temporary scaffolds that are later melted, to be replaced with living cells.

Researchers demonstrated the first step of this blood vessel building process in a recent study by creating scaffolds using a 3D “ice printing” technique. The scaffolds were then coated with a gel that was embedded with human cells, which the team grew for about two weeks.
