Human embryonic stem (hES) cells are defined by their extensive self-renewal capacity and their potential to differentiate into any cell type of the human body. The challenge in using hES cells for developmental biology and regenerative medicine has been to direct the wide differentiation potential toward the derivation of a specific cell fate. Within the(More)
Existing protocols for the neural differentiation of mouse embryonic stem (ES) cells require extended in vitro culture, yield variable differentiation results or are limited to the generation of selected neural subtypes. Here we provide a set of coculture conditions that allows rapid and efficient derivation of most central nervous system phenotypes. The(More)
The effects of in vivo administered amphetamine (4 and 15 mg/kg) on neuronal and unfractionated brain cortex protein synthesis were evaluated in albino rats. In vitro incubation of brain cortex prisms with 14C-leucine and bulk isolation of neuronal perikarya were performed 1 h after drug administration, and 14C was measured by liquid scintillation counting(More)
