91.   Analysis found that the new cells showed chemical markers and anatomical features typical of brain cells found in their area of the brain.

92.   As the human brain develops through the teen years, new cells or neurons grow by forming extensions and making millions of tiny connections.

93.   But the doctors speculate that the new cells help the hurt ones by restoring connections, releasing neurotransmitters and pumping in amino acids.

94.   But when the checkpoint genes fail, mistakes in DNA are perpetuated because the flawed cells then make new cells with the same genetic mistakes, or worse.

95.   By properly nurturing embryonic stem cells, experts say, they believe they can grow new cells to restore ailing organs in chronically ill patients.

96.   By properly nurturing embryonic stem cells, experts believe they can grow new cells to restore ailing organs in chronically ill patients.

97.   Each new cell will have a toilet, sink and a metal bed.

98.   Experts believe they can learn to direct the development of stem cells into various types of new cells that can rejuvenate or even replace ailing organs.

99.   Experts believe that by properly nurturing embryonic stem cells, they can grow new cells to restore ailing organs in chronically ill patients.

100.   Gould said more research is needed to understand exactly how the brain uses these new cells.
