The reaction of mesenchymal precursor cells depended on the dose of the enzyme. Administration of hyaluronidase in a dose of 20 U/mouse increased the content of stromal precursors and mesenchymal stem cells in the bone marrow and promotes mobilization of precursor cells induced by granulocyte CSF. Administration of high dose of hyaluronidase (100 U/mouse) reduced the content of mesenchymal precursors in hemopoietic tissue and abolished granulocyte CSF-induced mobilization of mesenchymal precursor cells of different maturity. 收起
