Scientists Can Now Grow Brain Cells In The Lab
H_Fisher writes "Scientists in Florida have grown mature brain cells in the laboratory, a scientific first. The Independent reports that "[...]they were able to produce virtually unlimited quantities of brain cells, which could revolutionise transplant medicine as well as leading to new drugs to stimulate the regrowth of damaged nerves." This could be a milestone in the treatment of Parkinson's Disease, Alzheimer's, and many other illnesses and injuries."
Just use the link for the "printer-friendly page". It's eye-friendly as well.

I don't really study neuroanatomy, but most patients with (hopefully repairable) brain damage aren't in need of an entire brain, they're in need of cells that produce specific chemicals. Parkinsons, for instance, is caused by a lack of Dopaminergic Neurons in a small portion towards the back of the brain; the ability to transplant new, fresh neurons may allieviate the symptoms.
A bit of an unfair comparison (because we can easily administer a drug and the injury is not nearly so severe) would be implanting cells that produce Lactase Enzyme for digesting dairy products in people who are lactose intolerant. It's not that the person needs a new stomach, they need a specific chemical which their brain cells are unable to make and we are unable to easily perscribe (dopamine precursors have lots of associated symptoms of their own).
