DH31 immunoreactivity in the larval gut.

<p>Parts of the midgut containing stained EECs are enlarged in the insets. DH31-immunoreactive EECs are located throughout the middle and posterior midgut, and are also densely distributed around the presumptive anterior-middle midgut junction. PV = proventriculus, aMG = anterior midgut, pMG = posterior midgut, HG = hindgut. Scale bars = 150 µm.
