A group of researchers in China and the U.S. has created a 3D-printed model of a cancerous tumor to help discover new anti-cancer drugs and better understand how tumors develop, grow, and spread throughout the body.

The model consists of a scaffold of fibrous proteins (gelatin, alginate, and fibrin) corresponding to the extracellular matrix (support structure) of a tumor, in the form of a grid structure 10… read more

Using a new gene-editing system based on bacterial proteins, MIT researchers have cured mice of a rare liver disorder caused by a single genetic mutation.

The findings, described in the March 30 issue of Nature Biotechnology, offer the first evidence that this gene-editing technique, known as CRISPR, can reverse disease symptoms in living animals. CRISPR, which offers an easy way to snip out mutated DNA and replace it with… read more

A team of scientists at the University of Edinburgh has rebuilt the thymus of an old mouse  — the first regeneration of a living organ.

After treatment, the regenerated organ had a structure similar to that found in a young mouse.

The  thymus is an organ in the body located next to the heart that produces important immune cells. The advance could pave the way for… read more
