Old Blood Cells Have Been Transformed Into Brain Stem Cells That Get Younger

"Scientists have transformed old blood cells into young brain stem cells, which continued to grow younger as they grew older," reports ScienceAlert:

Cellular transformations can be done in two main ways. The first, more circuitous route turns a specific cell back into a pluripotent stem cell, or an embryonic "blank slate," and then into a different cell type. The second method involves a "direct conversion," which skips the middle stage and directly transforms a cell into a different type.
"Using this method, we have directly converted red blood cell precursors into neural stem cells," summarizes Oliver Brüstle, the director of the Institute of Reconstructive Neurobiology at the University Hospital of Bonn...
