The radiobiological response of the thyroid Part I: Sheep thyroid cells in culture as a radiobiological model

Abstract
A system for culturing sheep thyroid cells in vitro is described. The properties of the cultures may be manipulated so that they preserve in vitro the follicular architecture typical of the thyroid, or so that they undertake cellular proliferation. The cultured cells also undertake I-metabolism. These growth and differentiation characteristics can be preserved for at least 3 wk, which is sufficient time for assay of many radiobiological end-points.
