A new technique, discovered by Tufts researchers, generates rapidly-differentiating human neural stem cells for use in a variety of tissue engineering applications. The researchers are not the first to generate these stem cells, but their process appears to be simpler, faster, and more reliable than existing protocols. They converted human fibroblasts and adipose-derived stem cells into stable, human induced neural stem cell (hiNSC) lines that acquire the features of active neurons within as few as four days, compared to the typical four weeks.
The work could pave the way for experiments that engineer other innervated tissues, such as the skin and cornea, and for the development of human brain models with diseases such as Alzheimer’s or Parkinson’s.
