This paper describes our study on the regeneration of hemopoietic and stromal components of bone marrow after mechanically emptying the medullar cavity of the guinea pig tibia. The intensity of hemopoiesis was determined from the number of hemopoietic cells, while the concentration and total number of stromal precursor cells were used to estimate the ability of the bone marrow to produce stromal structures, including its ability to restore a specific microenvironment. We found that there was no direct correlation between the recovery characteristics of hemopoietic and stromal cells. An increase in the population size of stromal precursor cells takes place early after curettage, and stromal fibroblasts become phosphatase-positive according to Gomori, which is characteristic of osteogenic tissue. We have also demonstrated that curettage of 3–5 tubular bones results in the growth of this cell population in the bone marrow of nonoperated bones and even in the spleen, which in guinea pigs participates only in lymphopoiesis.
