This is a single stem cell-derived neuron that has migrated away from the transplantation site in the cortex and grown into a mature neuron. The blue stain shows the nuclei of the endogenous neural cells in this part of the brain. (Credit: Courtesy, with permission: Weimann et al. The Journal of Neuroscience 2010.)From Science Daily:
Science Daily (Jan. 24, 2010) — Transplanted neurons grown from embryonic stem cells can fully integrate into the brains of young animals, according to new research in the Jan. 20 issue of The Journal of Neuroscience.
Healthy brains have stable and precise connections between cells that are necessary for normal behavior. This new finding is the first to show that stem cells can be directed not only to become specific brain cells, but to link correctly.
