Scientists Use 3-D Printer to Make Tissue-Like Material

April 4, 2013
"The droplets can be printed with protein pores to form pathways through the network that mimic nerves and are able to transmit electrical signals from one side of a network to the other."

WASHINGTON -- British scientists have used a custom-made 3-D printer to make living tissue-like material that could one day serve medical purposes, according to findings released Thursday.

The material is made up of thousands of connected water droplets, encapsulated within lipid films, that can carry out some of the functions of human cells.

These "droplet networks" could be the building blocks of a new technology used to pass on drugs and, down the road, could even replace damaged tissue, said a statement from Oxford University, where the scientists are based. Their findings were published in Friday's issue of the US journal Science.

Since the so-called droplet networks are completely synthetic, don't have a genome and don't replicate, they lack the problems linked with other methods of creating artificial tissues -- such as those using stem cells.

"We aren't trying to make materials that faithfully resemble tissues but rather structures that can carry out the functions of tissues," Hagan Bayley, a professor at Oxford's Chemistry Department who headed the research, said in a statement.

"The droplets can be printed with protein pores to form pathways through the network that mimic nerves and are able to transmit electrical signals from one side of a network to the other."

According to fellow Oxford scientist Gabriel Villar, "the printed structures could in principle employ much of the biological machinery that enables the sophisticated behavior of living cells and tissues."

 Each droplet measures about 50 microns in diameter (0.05 millimeters), or about five times the size of living cells. However, the researchers believe "there is no reason why they could not be made smaller."

This synthetic material can be designed to take on different shapes once printed.

In this way, a flat shape can be programmed to fold itself into a "hollow ball," the statement said.

As for the 3-D printer used, it was custom built at Oxford.

In February, researchers said they had engineered artificial human ears that look and act like the real thing thanks to 3-D printing.

Cornell biomedical engineers and Weill Cornell Medical College physicians said the flexible ears grew cartilage over three months to replace the collagen used to mold them.
