Fetal murine neuronal cells bear somatomedin receptors which can be classified according to their affinities for IGF-I, IGF-II and insulin. Binding of 125I-IGF-I is half-maximally displaced by 7 ng/ml IGF-I while 15- and 700-fold higher concentrations are required for, respectively, IGF-II and insulin. Linear Scatchard plots of competitive-binding data with IGF-I suggest one single class of type I IGF receptors (Ka = 2.6 X 10(9) M-1; Ro = 4500 sites per cell). The occurrence of IGF-II receptors appears from the specific binding of 125I-IGF-II and competition by unlabeled IGF-II; the IGF-II binding sites display a low affinity for IGF-II and no affinity for insulin. IGF-II also interacts with insulin receptors although 50- to 100-fold less potent than insulin in competing for 125I-insulin binding. The presence of distinct receptors for IGF-I, IGF-II and insulin on fetal neuronal cells is consistent with a role of these peptides in neuronal development, although our data also indicate that IGF-I receptors could mediate the growth promoting effects of insulin.
