Fig. 2From: The role of the prostaglandin E2 receptors in vulnerability of oligodendrocyte precursor cells to deathExpression of EP receptors in purified oligodendrocytes. Purified OPC cultures were stained with the oligodendrocyte marker Olig 1 (green) and EP1 through EP4 (red) as indicated. Co-expression appears yellow, and examples are indicated with arrows. The asterisk indicates an example where immunoreactivity for EP2 is present predominantly in the cell processes. The bar in the lower corner is 20 μmBack to article page
