we were unable to demonstrate an autocrine role for igf in the c6 glial cell line , since [ 3h ] thymidine incorporation into dna was stimulated equally well by igf-i-deficient rat serum and normal serum , and added igf did not stimulate [ 3h ] thymidine incorporation into dna when tested alone or when added to igf-i-deficient serum .
