Specific activity of electron-beam synthesis immobilized hyaluronidase on G-CSF induced mobilization of bone marrow progenitor cells.

The effects of nanotechnology (electron-beam) -PEGylated (or immobilized; Im) hyaluronidase (HD) on the state of the pool of bone marrow progenitor cells and their mobilization induced by granulocyte colony stimulating factor (G-CSF) were studied. A high specific activity of the drug Im-HD on progenitor cells of different classes was demonstrated using parenteral and enteral administration. An increase in the content of erythroid (E), granulomonocytic (GM), fibroblast (F) colony-forming units (CFU) and mesenchymal stem cells (MSC) in bone marrow was shown, as well as G-CSF-induced stimulation of mobilization of precursors into the peripheral blood under the influence of Im-HD. The detected activity of this novel drug on progenitor cells indicates the potential for a safe and highly effective treatment for hematology practice and regenerative medicine.
