    Cloned cells treat Parkinson's in mice

    From correspondents in Washington

    RESEARCHERS who used cloned embryonic stem cells to treat Parkinson's disease in mice said today 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," Ms Tabar said.

    The mice given non-matched brain cells did more poorly than the mice given cells from their own clones, the researchers reported in the journal Nature Medicine.

    Stem cells are the master cells of the body and embryonic stem cells are the ultimate master cells, giving rise to all the other cells and tissue. Cloning researchers hope one day to be able to take a little piece of skin and grow embryonic stem cells from it for personal, tailor-made medical treatments.

    One disease always named that may benefit from this technology is Parkinson's. The incurable, fatal illness is caused by the destruction of specific brain cells.

    Researchers found mouse's own cloned stem cells worked best

    WASHINGTON - 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.

    of course ....every patient is unique.my body will reject cells from another body.why took them so long to discover ?sorry if i am wrong .a simple blood transfusion is a diffrent issue regarding rejections and compatibility.
