Effect of radiation, thermal or combined radiation-thermal damage to a population of progenitor cells of the granulocyte-macrophage series in mouse bone marrow

The recovery of a population of granulopoietic-monocytic colony-forming units of mouse bone marrow was only slightly inhibited during the first two weeks after exposure to a mixture of radiation (4 Gy) and heat (burn of 10 per cent of the skin). In the interval between days 14 and 28 following the effect, their number reached the control level, then it decreased again.
