A platform called bio-thermal scanning probe lithography (bio-tSPL), takes a "photograph" of the bone tissue, and then uses the photograph to produce a replica of it.

A "bio-ink" for 3D-printed materials could serve as scaffolds for growing human tissues to repair or replace damaged ones in the body, say bioengineers.

Synthetic cell scaffolds that let scientists test cancer cell growth in different environments could be a way to replace animal testing in cancer research.

Bioengineers are using grooves to seed sophisticated, 3D-printed tissue-engineering scaffolds with living cells to help heal injuries.
