Extended Data Figure 9: CM-DiI fate-mapping of the primitive gut in sturgeons, with endodermal contribution to the orofacial surface.
From: Pre-oral gut contributes to facial structures in non-teleost fishes
a–d, Experimental sturgeon embryos showing the extent of CM-DiI (red) at stages just before (a), during (b), and after (c, d) mouth opens. Left to right show lateral views, ventral views, SEM images, and schematics. e–j, Sturgeon embryos; bright field images, showing the presence and extent (red arrows) of the yolk-rich cells of the foregut endoderm. These cells appear full of bright yolk granules, which gradually disappear during later development (i, j).
