| Sumario: | Mechanisms by which HSCs mobilize into damaged organs are currently under scrutiny.Macrophage role in these processes is investigated. In this study, we performed a flow cytometry analysis ofCD117+CD38+ and CD117+CD90low HSCs quantity in murine peripheral blood and bone marrow after liverand kidney injury under stimulation of phagocyte mononuclear system by injection of tamerit. This study havedemonstrated increased levels of CD117+CD38+ HSCs in bone marrow after partial hepatectomy, along withtheir migration to peripheral blood in response to tamerit injection. We also demonstrated that peripheralblood CD117+CD38+ HSCs levels were elevated after kidney injury. After partial hepatectomy, nochangesof CD117+CD90low HSCs quantity in investigated tissues were detected. We observed increased number ofCD117+CD90low HSCs in murine blood following kidney injury. Thus, we observed different influence ofmacrophage stimulation on the quantity of CD117+CD38+ and CD117+CD90low cells. These data suggestthat HSCs mobilization from the bone marrow to peripheral blood depends, at least in part, on phagocytemononuclear system, and that macrophage stimulation is important for proliferation and migration of variousHSCs populations following liver and kidney injury. |
