A report published in Nature Medicine has revealed that the U. S. scientists have produced working liver grafts in the lab. The research conducted by Massachusetts General Hospital can open the doors for growth of the livers for transplants. Scientists have created these liver grafts by using cells of rat. This is a great invention in the health area.

In their study, the scientists first flushed out the liver cells and left a tissue named scaffold. Scientists then introduced a liver cell known as hepatocytes. This liver cell repopulated the left tissue scaffold.

Then the scientists relocated them into the rats, along with their normal livers. It was found that the transplant tissues functioned properly for a short duration. Scientists have created these liver cells in the lab, however, the trouble in making them work and joining them with the part of an organ still prevails.

This graft is functional only for a short time and to make it more effective for long term, a lot of work by scientists is required.

According to Mark Thursz, who is a Professor of Hepatology at Imperial College, London, there are some more issues and concerns that are needed to be taken care of, after that only the implant of these livers would be possible.

According to him, there are more cells which are required for producing the liver grafts in order to make them work properly.
