Fig. 8. Basement membranes are disrupted in laminin B mutants. Mutations in the laminin epi-1 gene disrupt the integrity of basement membranes. In the body cavity, multiple layers, large whorls (wh) and clumping (cl) of material are common in adult animals. This electron micrograph shows a region between the gonad and intestine, a germ cell (g) and yolk (y) are indicated. Scale bar: 5 µm.
