This work was aimed at investigating radiation-induced hemopoietic and immune dysfunction in the dog model. One project was to produce monoclonal antibodies directed against canine hemopoietic precursor cells and select for pluripotent stem cells. Antibodies obtained reacted with different myeloid and erythroid precursor cells; unfortunately, none of the antibodies were specific for pluripotent hemopoietic stem cells. Positive selections for these cells were performed using magnetic beads and an antibody against ...
