CELL PROLIFERATION IN THE ADRENAL OF CONTROL AND COLD EXPOSED RATS,
Abstract
Tritiated thymidine coupled with high resolution radioautography was employed to assess new cell formation in the adrenal of control rats and of animals after different periods of cold exposure. Evidence is presented for new cell formation in each of the three cortical zones of controls and of experimental rats during all periods of cold exposure. Cold exposure effected an increase in new cell formation within the glomerular and fasciculate zones but not in the reticular zone. The results support the concept of functional independence of the three cortical zones. A small percentage of the chromaffin cells of the adrenal medulla was labeled in both control and experimental animals, indicating a slow rate of renewal that seemed not to be changed by cold exposure.
