The effect of glutamate receptor activation on dendritic differentiation of Purkinje cell. Purkinje cells were cultured in the absence (left) or presence (middle) of 10 μm CNQX and 1 mm MCPG for 14 d, followed by fixing and double immunostaining for calbindin D-28K and NSE. The Purkinje cell in theright was cultured with similar concentrations of CNQX and MCPG in a high-potassium-containing medium (20 mm). Scale bar, 50 μm. Quantitative analysis of the dendritic differentiation is shown in Table 1.
