Abstract

The bone marrow-derived stem/progenitor cells were demonstrated to play an important role in a regeneration of damaged tissue. Based on these observations we asked whether the stroke-related stress triggers mobilization of stem/progenitor cells from the bone marrow into the peripheral blood, which subsequently could contribute to regeneration of damaged organs. To address this issue, the peripheral blood samples were harvested from patients with ischemic stroke during the first 24 hrs as well as after the 48 (2nd day) and 144 hrs (6th day) since the manifestation of symptoms. In these patients we evaluated the percentage of hematopoietic stem/progenitor-enriched CD34+ cells by employing flow cytometry and the number of hematopoietic progenitor cells for the granulocyto-monocytic (CFU-GM) and erythroid (BFU-E)-lineages circulating in peripheral blood. We concluded that stress related to ischemic stroke triggers the mobilization of hematopoietic stem/progenitor cells from the bone marrow into peripheral blood. These circulating stem/progenitor cells may play an important role in the process of regeneration of the ischemic tissue.
