title: Evidence of calcitonin-induced inhibition of calcitonin secretion in porcine thyroid slices.
abstract: In the present study, the possibility of calcitonin-induced self-inhibition in porcine thyroid slices was examined. Replacing the incubation medium at 5-min intervals during incubation and increasing the volume of incubation from 2 to 15 ml were observed to enhance calcium-stimulated calcitonin secretion in vitro.
