The Independent reports researchers from the Stanford University School of Medicine have converted adult skin cells directly into mature nerve cells:
Skin cells from a 30-year-old woman have been turned directly into mature nerve cells similar to those found in the brain using a procedure that promises to revolutionise the emerging field of regenerative medicine. Scientists said they were astonished to discover that they could convert a person's skin tissue into functioning nerve cells – bypassing an intermediate stem-cell stage – by the relatively simple procedure of adding a few short strands of RNA, a genetic molecule similar to DNA. The breakthrough could soon lead to the generation of different types of human brain cells in a test tube which could be used to study a range of neurodegenerative conditions such as Parkinson's and Alzheimer's disease.
