Effect of Calcium on Mitosis in the Thymuses of Normal and Irradiated Rats

Naturevolume 214pages302303 (1967) | Download Citation



THE demonstration that increased levels of calcium in cultures of strain L mouse fibroblasts and rat thymocytes stimulated mitosis and reduced, or prevented, the transient mitotic delay produced by irradiation1,2 led to the hypothesis that a rise in the concentration of calcium in the blood and tissues might also stimulate normal mitosis and reduce post-irradiation mitotic delay in the whole animal.
