Fig. 5. Relative percentage of PNA and PNA+ cell types
in populations of gill cells isolated from the MR 1.051.09 g
ml1 Percoll interface. Control fish (freshwater) are
compared with seawater-adapted fish at partial-strength (10
) and
full-strength seawater (30
). PNA+ and PNA
cells counted under 100x objective of fluorescence microscope with a
minimum of five fields of view counted for each freshwater and seawater fish.
Values represent means ± S.E.M.
(N=6 fish for each treatment group).
