Figure 1. The density of neurons and ENC cells increases in the quail embryo midgut myenteric plexus, but the ratio stabilises.

A. The density (number per 100×100 μm area) of neurons (Hu; red), ENC cells (SoxE; blue) and total ENS cells (Hu plus SoxE; purple) increases from QE4.5 to QE8. B. The ratio of neurons to ENC cells stabilises by E6. Error bar=SEM.
