Growing functioning brain tissue in 3-D

Researchers at the RIKEN Center for in Japan have succeeded in inducing human to self-organize into a three-dimensional structure similar to the cerebellum, providing tantalizing clues in the quest to recreate neural structures in the laboratory. One of the primary goals of stem-cell research is to be able to replace damaged body parts with tissues grown from undifferentiated stem cells. For the nervous system, this is a particular challenge because not only do specific neurons need to be generated, but they must also be coaxed into connecting to each other in very specific ways.

Grown from Human Embryonic Stem Cells
CALB and L7 are Purkinje-cell specific late markers are shown. GRID2 is a marker for a Purkinje-specific glutamate receptor. LHX5 is a marker for early .
