Abstract: | The content of stromal clonogenic cells in hemopoietic and lymphoid organs of mice and guinea pigs decreases with age. This drop is most pronounced in the thymus of mice and guinea pigs and in mouse spleen (more than 12-, 75-, and 8-fold, respectively). The contents of stromal clonogenic cells in the bone marrow of old mice and in the spleen of old guinea pigs are reduced by 50 and 40%, respectively, in comparison with young animals. These data indicate that the content of committed and inducible osteogenic precursors can decrease with age.
