Scientists Create 'Mini Livers' to Help People with Liver Disease

Topic: Health

MIT scientists have developed a way to create tiny livers that can be injected into the body. These mini livers can help people with liver disease by providing some of the functions normally carried out by a damaged liver. The researchers tested this approach in mice and found that the mini livers worked for at least two months.

More than 10,000 people in the United States are waiting for a liver transplant because they have chronic liver disease. However, there aren't enough donated organs to go around. MIT engineers have been working on a solution: injectable 'mini livers' that can provide some of the functions normally carried out by a damaged liver.

The researchers created these mini livers using liver cells and tiny hydrogel microspheres. The microspheres help keep the cells together and encourage them to connect with nearby blood vessels. This makes it possible for the mini livers to function properly inside the body.

In their study, the MIT team tested the mini livers in mice. They found that the injected liver cells remained alive for at least two months and continued producing many of the enzymes and proteins normally generated by the liver. The researchers believe that these mini livers could be used as a temporary solution to help people with liver disease while they wait for a transplant.

The MIT team also developed a way to deliver the mini livers using an ultrasound-guided syringe. This allows doctors to track the implant and determine whether it remains stable over time.

Why It Matters

This research could have a big impact on people with liver disease in India, where access to liver transplants is limited. If this technology becomes available, it could provide a new hope for those waiting for a transplant.
