Gene controls neural stem cell growth
...e found that mutant neurospheres proliferated more readily than normal neurospheres, said Wu. Also as in the in vivo studies, we found that the mutant neurospheres, like the normal neurospheres, produced the normal range of neural cells neurons, astrocytes and oligodendrocytes.

...bilical cord blood may be a noncontroversial, more readily available source of therapeutic cells for treating early stroke and other traumatic brain injuries," said Paul Sanberg, PhD, DSc, director of the USF Center for Aging and Brain Repair and a senior author of the report.

"FirstEF is the first program that can readily and accurately detect a class of gene segments that has previously been extraordinarily difficult to find," says Zhang. "It's like looking for buried treasure." The gene segments Zhang is referring to occur at the very beginning of genes, and are cal...A little larceny comes naturally to Northwestern crows
