The present study investigates the expression of IGF-I in the early developing tilapia (Oreochromis niloticus). IGF-I was detected very early in ontogeny (4-5 days postfertilization, DPF), first in liver and in organs involved in growth and metabolism, thus suggesting a high physiological impact of IGF-I in growth, metabolism, and organogenesis.
