[Differentiation of hematopoietic and stromal elements of extramedullary bone marrow transplants in irradiated recipients].

The growth of bone marrow transplants under the renal capsule is stimulated in the mice irradiated at a dose of 700 r. The size of transplants increases, primarily, at the expense of hemopoietic tissue. The osteogenic potencies of stromal elements remain at a high enough level as well. Some features which characterize the decrease of viability of hemopoietic cells may be due to incomplete restoration of the system of sinusoidal capillaries.
