Examples

  • On the other hand, exercise results in a marked increase in the production of stem cells and new motor neurons—those same motor neurons that are so essential for remyelinating myelin sheaths and axonal nerves in neurological autoimmune disease.

    The Autoimmune Epidemic

  • According to Douglas Kerr, stress, depression, and interrupted sleep patterns all have a negative effect on the body: these events “decrease the rate at which stem cells divide and create new stem cells in the bone marrow; they cause stem cells to go quiet.”

    The Autoimmune Epidemic

  • Although researchers have tried to use already-differentiated stem cells—taken from umbilical-cord blood, thus negating the need to use controversial embryonic stem cells—experiments striving to use this line of stem cells to regrow nerves have failed.

    The Autoimmune Epidemic

  • It is intensely regrettable that the product of SCNT has been equated both in terminology and in moral argument with the generation of stem cells from a human embryo derived from the union of sperm and egg.

    The Language of God

  • Kerr had to find a way to prompt these undifferentiated mouse embryonic stem cells to differentiate into motor neuron cells in such a way that they would go on to create axonal nerves covered with myelin sheaths—a fatty insulating tissue—that together make up the elaborate electrical highway that constitutes the nervous system.

    The Autoimmune Epidemic

  • Undifferentiated stem cells are kind of like college freshmen who haven’t yet decided what subject they want to major in.

    The Autoimmune Epidemic

  • Although the idea of using embryonic stem cells for research is one that each scientist, politician, and voter must wrestle with for him-or herself, when the question arises among the four hundred sufferers of multiple sclerosis at the annual MS meeting where Kerr recently detailed his work on stem cells, their position is unanimous: embryonic stem cells hold the potential promise for them to live normal lives as mothers and fathers.

    The Autoimmune Epidemic

  • It is in this lab that the forty-year-old Kerr has developed what he likens to a step-by-step cookbook recipe on how to use embryonic stem cells to restore lost nerve function in paralyzed mammals.

    The Autoimmune Epidemic

  • He lowers his hands to stem the tide of applause, eager to explain to the crowd how, utilizing embryonic mouse stem cells in a novel set of strategic scientific steps, he has been able to regenerate the damaged axonal nerves and myelin sheaths in paralyzed rats.
