Fig. 8.

SBF SEM from the central posterior cornea of a 13-week-old human foetus (Cornea 6). Fig. 8A shows the presence of elastic fibers (gold) above a meshwork of dark filaments which will later become Descemet's membrane. Because of the oblique imaging plane, some stroma above the fibers is seen at the top left of the image. Fig. 8B, acquired from a different orientation shows elastic fibers (gold) immediately above the endothelium (light green). The full three-dimensional structure is seen in Video clip S5. (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.)
