Effect of NAM on the ultrastructure of the regenerated lens. Transmission electron microscopy (TEM) showing the cellular degeneration and arrangement between untreated control (CON, a and d), NAM-treated regenerated lenses (NAM, b and e) and normal lenses (NOR, c and f). Red arrowheads indicate membrane interdigitations of the LFCs. Scale bar: a–c 2 μM, d–f 1 μM
