When the right gene is expressed in the right manner in the right population of stem cells, the developing mouse brain can exhibit primate-like features. In a paper publishing August 7th in the Open Access journal PLOS Biology, researchers at the Max Planck Institute of Molecular Cell Biology and Genetics (MPI-CBG) succeeded in mimicking the sustained expression of the transcription factor Pax6 as seen in the developing human brain, in mouse cortical progenitor cells. This altered the behavior of these cells to one that is akin to that of progenitors in the developing primate neocortex. Consequently, the mouse progenitors generated more neurons - a prerequisite for a bigger brain.
