Primary cell cultures of normal and adenomatous human thyroid tissues were incubated with TSH or ammonium sulphate precipited IGG fractions (1 mg/ml) of sera from patients with different thyroid diseases (Graves' disease: active n = 7 in remission n = 12; thyroid autonomy n = 39; simple euthyroid goitre n = 15) and were compared to controls (n = 26). [3H]thymidine incorporation in primary thyrocyte cultures demonstrated a typical bell shape curve after incubation with EGF and TSH with a maximal effect at 10-100 microIU/ml. This effect, however, was inconsistent and positive only in 2 of 7 primary cultures. Only TSH positive cultures were used for IgG studies. 16-28% of IGG fractions from sera of thyroid patients caused high (more than X + 5 SD of controls) stimulation of [3H]thymidine incorporation. Dose response curves of IgG fractions of 19 additional patients (Graves' disease in remission n = 15; thyroid autonomy n = 4) showed an increase in [3H]thymidine incorporation at 0.1 mg protein/ml for 10 patients and at low concentrations of 10-5 mg/ml for 5 patients. There was a good correlation (r = 0.72) (P less than 0.0001) between positive findings in TSH-binding inhibition (TBII) and AC-stimulation (TSI) IGG fractions but none between stimulation of [3H]thymidine incorporation and any other thyroid specific immunoglobulin nor thyroid function nor any other available data. Immunoglobulins stimulating [3H]thymidine incorporation differ therefore from TBII and TSI. The growth effect of these immunoglobulins, however, has yet to be determined.
