Human stem cells help blinded rats: study

Human embryonic stem cells can partly restore vision in blinded rats, and may offer a source of transplants for people with certain eye diseases, researchers at a U.S. company reported on Thursday.

The finding, published in the journal Cloning and Stem Cells, might offer a way to use stem cells that now exist in laboratories, the researchers said.

“We have developed a technology that we hope can be used to treat degenerative eye diseases such as macular degeneration,” said Dr. Robert Lanza of Advanced Cell Technology in Worcester, Massachusetts, who led the study.
