2'09''A Japanese group has generated homan liver using certain adults' tissue cells along with two other standard human cells. This kind of liver will not created self-rejected in receptors. When scientists transplanted the liver into the mice's body, the liver functioned normally and successfully induced the protein typically in human's livers. This is a breakthrough in regenerating medicine.
1'13'' But this new finding has lots of difficulties reaching the clinics, including safety checks and cells proliferation problems. It may take decades to totally solve the problems.
