title: Various Cell Populations Within the Mononuclear Fraction of Bone Marrow Contribute to the Beneficial Effects of Autologous Bone Marrow Cell Therapy in a Rodent Stroke Model.
abstract: Cell-based therapies including bone-marrow derived mononuclear cells (MNCs) are now widely being studied because of their pleotropic effects and promising results to improve recovery after stroke in animal models. Unlike other types of cell therapies, MNCs is a mixture of lymphoid, myeloid, erythroid, and stem cell populations. Which cell population(s) accounts for the beneficial effects of MNCs in stroke recovery is unclear. In this paper, we employed a mouse stroke model with middle cerebral artery occlusion (MCAo), and used positively and negatively sorted autologous MNCs by MACs to determine which fractions of the MNCs contribute to their beneficial effects. We evaluated the benefits of neurofunctional recovery produced by individual cell lineages within MNCs in a long-term observation study up to 28 days after stroke. Mortality and modulation of inflammation were also compared among different sub-populations. We further studied the impact of neurotoxicity posed by activated microglia in the presence of different cell lineages within MNCs. We concluded that myeloid cell lineage and stem cell/progenitors appeared to be important components within MNCs that contribute to improved outcomes after stroke.
