[Quantitative characteristics of the transfer of the hematopoietic microenvironment]

Heterotopic transplantation of marrow fragments results in the formation of new bone marrow organs. The amount of hemopoietic cells populating these organs is connected nonlinearly with the volume of the grafted tissue or with the number of transplanted marrow cells. Statistical analysis points out that the number of the populating cells depends on the radius of the initial bone marrow transplant. Thus, the previous data on the radiosensitivity of the microenvironmental transfering stromal cells and on their concentration obtained by measuring the size of the heterotopic bone marrow organs have turned out incorrect.
