Figure 6

Transmission electron microscopy (TEM) characterizes glial cells and axon ultrastructure within the larval zebrafish foregut. TEM reveals ultrastructure of myenteric plexus neuropil of the foregut in (A,B′) 7 dpf and (C–E′) 18 dpf larvae. Magenta-dashed box corresponds to region of magnification (A′–E′). Intestinal epithelium (IE), nucleus (N), nuclear body (NB), muscularis (M), axon (Ax), type 1 glia (T1G) and type 2 glia (T2G). Scale bars denote the following: (A) 500 nm, (A′) 250 nm, (B) 500 nm, (B′) 250 nm, (C) 500 nm, (D) 200 nm, (E) 1 micron and (E′) 500 nm. Yellow arrows in (A) point to large granular vesicles, black arrowheads in (B′) and white arrowheads in (D,E′) point to caveolae.
