A method of priming neural stem cells in vitro by adhesively culturing in a mixture of basic fibroblast growth factor, laminin and heparin to differentiate into specific neuronal phenotypes, including cholinergic, glutamatergic and GABAergic neurons, in a region-specific manner, when transplanted in vivo. The polymeric layer may also include a prepared surface on a portion thereof, the release liner being positioned over the prepared surface. 1 to 200 wt parts of a carbodiimide and an organosilicon crosslinking agent, or alternatively by thermally curing a silicone resin composition including 100 wt parts of an OH-containing polysiloxane, 0. The matrix that relates velocity to the tomographic data in the non-uniform representation is then given by the matrix product of the corresponding matrix in the uniform grid representation and the mapping matrix. The first and second polymers are reacted by mixing and forming a blend with improved physical properties over a blend of similar polymers lacking a reactive amine group.
