Japanese scientists have just announced the successful transplants of human skin cells, opening hope for many blind people around the world.
According to Nature Cell Biology, the scientists used mouse embryonic stem cells to induce human stem cells to become urinary state - the initial form of human kidneys.
After an initial successful test in mice, Chinese scientists believe that stem cells derived from urine can help humans re-grow lost teeth.
US scientists have found a new way to create human stem cells, allowing the replacement of embryonic stem cells to treat diseases.
According to research by scientists, this new method will replace the use of these cells in the treatment of disease.
