WASHINGTON (Reuters) - Researchers who used cloned embryonic stem cells to treat Parkinson's disease in mice said on Sunday they worked better than other cells.

The researchers were trying to prove that it is possible to make embryonic stem cells using cloning technology and use them to provide a tailor-made treatment.

But they found that a mouse's own cloned stem cells were far less disruptive to its body than cloned cells taken from other mice.

"It demonstrated what we suspected all along -- that genetically matched tissue works better," said Viviane Tabar of Memorial Sloan-Kettering Institute in New York, who worked on the study.

"When you give the other type of tissue, non-autologous tissue, you get more inflammation than we anticipated. This is in a lab animal where we expect it to be tolerant. Normally when you do this in mice, you don't give matched cells," Tabar added in a telephone interview.
