This will accelerate organ cloning and updating the genetic code of said organs, a crucial thing if we are to both reverse aging in organs and remove genetic diseases and other issues.
Quote: The researchers dubbed this new class of cells "region-selective pluripotent stem cells," or rsPSCs for short. The rsPSCs were easier to grow in the laboratory than conventional human pluripotent stem cells and offered advantages for large-scale production and gene editing (altering a cell's DNA), both desirable features for cell replacement therapies.
"The region selective-state of these stem cells is entirely novel for laboratory-cultured stem cells and offers important insight into how human stem cells might be differentiated into derivatives that give rise to a wide range of tissues and organs," says Jun Wu, a postdoctoral researcher in Izpisua Belmonte's lab and first author of the new paper. "Not only do we need to consider the timing, but also the spatial characteristics of the stem cells. Understanding both aspects of a stem cell's identity could be crucial to generate functional and mature cell types for regenerative medicine."
