RNA induced Pluripotent Cells

Another step toward living forever

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.

A new, better way to make stem cells

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.

That's really amazing, a stem cells that have the potential to be almost any type of body part. This is a promising method for reprogramming somatic cells to pluripotency. The fact that this approach can reprogram multiple human cell types to pluripotency is really a big step towards medicine. Really nice post I really like it.
