5-HT activates MAPK in cultures of dissociated cells from fetal gut (E13). Phosphorylated MAPK was demonstrated immunocytochemically. Cells are visualized by interference contrast microscopy. A, Control. No nuclear immunoreactivity is demonstrable. Cells with a neuronal morphology (▸) are indicated.B, 5-HT (1 μm; 45 min). MAPK immunoreactivity (→) can be seen in the nuclei of a subset of cells with a neuronal morphology; additional cells with a neuronal morphology are not immunoreactive (▸). Scale bars, 50.0 μm.
