However, mechanisms of possible protective or reparative effects are poorly understood. In this study we analyzed the effect of lineage-negative bone marrow-derived hematopoietic stem and precursor cells (Lin\n            <jats:sup>\u2212<\/jats:sup>\n            -HSCs) on ischemic brain injury in mice.\n          <\/jats:p>\n          <jats:p>\n            <jats:bold>\n              <jats:italic>Methods\u2014<\/jats:italic>\n            <\/jats:bold>\n            Lin\n            <jats:sup>\u2212<\/jats:sup>\n            -HSCs were injected intravenously at 24 hours after onset of a 45-minute transient cerebral ischemia.
