Lattice and rodlet nuclear inclusions in Merkel cells in rabbit epidermis.

A latticee or rodlet inclusion is occasionally observed in the nucleus of a Merkel cell. The lattice has the external form of a plaque or band and internally consists of alternating parallel wide and narrow layers. Filaments in wide layers run in at least two directions across the short dimension of the inclusion. In contrast, the rodlet is a bundle of parallel filaments running the long dimension of the inclusion. Filaments in lattices and rodlets possibly contract and agitate the highly folded nucleus of the Merkel cell.
