title: [Characteristics of hematopoiesis regeneration in subcutaneous bone implants in aging mice].
abstract: Femurs from both young and old mice were implanted subcutaneously to young syngeneic recipients. 2-2.5 months after surgery femoral marrow grafts were repopulated with nucleated cells and macrophage-granulocyte precursor cells irrespective of the donor's age. Marrow depletion of femurs prior to implantation caused a sharp decrease in hemopoietic repopulation of implants from old, but not young, donors. It is concluded that age-dependent functional peculiarities of stromal microenvironment can be visualized owing to the extraordinary local regenerative demand.
