The lamina lucida is a component of the basement membrane which is found between the epithelium and underlying connective tissue (e.g., epidermis and dermis of the skin). It is a roughly 40 nanometre wide electron-lucent zone between the plasma membrane of the basal cells and the (electron-dense) lamina densa of the basement membrane.[1]
Similarly, electron-lucent and electron-dense zones can be seen between enamel of teeth and the junctional epithelium. The electron-lucent zone is adjacent to the cells of the junctional epithelium and might be considered a continuation of the lamina lucida as both are seen to harbour hemidesmosomes. However, unlike the lamina densa, the electron-dense zone adjacent to enamel show no signs of hemidesmosomes.[2]
Some theorize that the lamina lucida is an artifact created when preparing the tissue, and that the lamina lucida is therefore equal to the lamina densa in vivo.[3]
