[The role of the thymus in regulating the stromal cells responsible for the transfer of the hemopoiesis-inducing microenvironment in stress].

The role of thymus in the regulation of stromal elements, responsible for haemopoiesis inducing microsurrounding transfer of animals, subjected to 10-hours immobilization, was studied. The development of bone marrow hyperplasia and stimulation of functional activity of stromal cells, responsible for haemopoiesis inducing microsurrounding transfer, were shown to be thymus dependent processes during stress.
