TL;DR: The data suggest a hyperosmoregulatory role of IGF-I in this species and Immunohistochemistry revealed for the first time in teleosts that IGF-IR and Na(+)-K(+-ATPase are localized in putative chloride cells at the base of the lamellae, identifying these cells in the gill as a target for IGF-i and IGF-II.
