words only definitions & notes
  1. stem cell
    an undifferentiated cell whose daughter cells may differentiate into other cell types (such as blood cells)

  11. cardiac
    of or relating to the heart
    If doctors can figure out exactly how the cells repair and regenerate cardiac tissue, stem cell therapies could offer hope to more than 17.6 million Americans who suffer from coronary disease.
  12. therapy
    the act of providing treatment for an illness or disorder
    If doctors can figure out exactly how the cells repair and regenerate cardiac tissue, stem cell therapies could offer hope to more than 17.6 million Americans who suffer from coronary disease.
  13. lab
    a workplace for the conduct of scientific research
    In his University of Central Florida lab, Steven Ebert engineered stem cells with the same enzyme that makes fireflies glow.
  14. coronary
    surrounding the heart like a crown
    If doctors can figure out exactly how the cells repair and regenerate cardiac tissue, stem cell therapies could offer hope to more than 17.6 million Americans who suffer from coronary disease.
  15. regenerate
    reestablish on a new, usually improved, basis
    If doctors can figure out exactly how the cells repair and regenerate cardiac tissue, stem cell therapies could offer hope to more than 17.6 million Americans who suffer from coronary disease.
  16. glow
    emit a steady even light without flames
    tem cells that glow like fireflies could someday help doctors heal damaged hearts without cutting into patients' chests.
  17. damaged
    harmed or injured or spoiled
    tem cells that glow like fireflies could someday help doctors heal damaged hearts without cutting into patients' chests.
  18. heal
    recover
    tem cells that glow like fireflies could someday help doctors heal damaged hearts without cutting into patients' chests.
  19. microscope
    magnifier of the image of small objects
    Now Ebert's cells give researchers the ability to see the cells in action with the use of a special camera lens that picks up the glow under a microscope.
  20. lens
    a transparent optical device used to form images
    Now Ebert's cells give researchers the ability to see the cells in action with the use of a special camera lens that picks up the glow under a microscope.
  21. cavity
    a space that is enclosed or surrounded by something
    The glow of the enzyme also means therapies would no longer require cutting into patients' chest cavities to monitor the healing.
  22. transplant
    transfer from one place or period to another
    Researchers are keenly interested in stem cells because they typically morph into the organs where they are transplanted.
  23. monitor
    someone who observes to ensure fairness or prevent mistakes
