The Effect of Irradiation on Osteoclasts with or Without Transplantation of Hematopoietic Cells

Abstract
The sensitivity of the osteoclasts to large doses of irradiation is less than that of the cells in bone marrow and thymus. After irradiation, the number of osteoclasts decreases first after the 7th day. Transplantation of cells from bone marrow and spleen restores the number but cells from thymus, or thymus cells in combination with macrophages, do not have this effect.
