Various ultrastructural alterations appear in the pillar cells of the gill lamellae of M.
In the gill epithelium of Macrobrachium olfersii, the apical surface of the pillar cells is highly amplified by an extensive system of microvilli (type 2, see Cioffi, 1984).
olfersii attests to a dual role for the pillar cells in the regulatory physiology of the gill.
The notable reductions in the height and numerical density of the microvilli on the apical surface of the pillar cells, and in the thickness of the flanges, which occur as a result of acclimation to saline media in M.
These various data demonstrate the labile nature of the apical infoldings of the epithelial and pillar cells in the gill lamellae of osmoregulating crustaceans.
