[Phagocytic capacity of hematopoietic tissue stromal precursor cells].

A method of removal of phagocytising elements from the cell suspension by means of iron powder in magnetic field was used. Clonogenic fibroblast precursors of the hemopoietic tissue not belonging to histiocytes-macrophages, but referred to mechanocytes, were characterised by high phagocytic activity. Following Fe treatment less than 1% of clonogenic fibroblast precursors which gave rise to fibroblast colonies under conditions of monolayer cultures remained in the bone marrow cell suspension, and about 10%--in the spleen and the peritoneal exudate cell suspension.
