Fig. 1. Transmission electron microscopy of fibrillin-rich microfibrils and elastic
fibres. (A) Human ciliary zonular microfibrils in loose, roughly parallel
arrays. (B) Lobster aorta microfibrils, showing periodic striations. (C)
Deposition of microfibrils and elastin by cultured bovine nuchal ligament
fibroblasts. (D) Close-up of elastic fibres forming in bovine nuchal ligament
fibroblast cultures. (E) Internal elastic lamina (IEL) of murine aorta, with
associated endothelial cell (EC) and smooth muscle cell (SMC).
