Stem cells have the potential to become almost any type of body part. I believe they will soon be used to rejuvenate, repair, or rebuild body parts. Look at our past Science Buzz posts about stem cells. Bad knees or hips? Inject some stem cells to rebuild the cartilage. Stem cells also can repair cut spinal cords, damaged eyes, diseased brains, or help a diabetic's pancreas make insulin.
Up until now, the stem cells created by reprogramming adult skin cells still had bits and pieces remaining that were not safe enough for human applications.
"Now stem cell researcher Derrick Rossi of Harvard Medical School in Boston and his colleagues have developed a way to reprogram cells using synthetic RNA molecules." (Science Magazine) The technique is also twice as fast and 100% more efficient. The team calls its cells RiPS cells, for RNA induced Pluripotent Cells.
The new technique, is published online in the journal, Cell Stem Cell.
