Abstract: This study demonstrated a therapeutic benefit of a single intravenous infusion of DS-1 cells during the subacute MI period. Based on cell out-growth and DS-1 specific PCR assays there were no detectable DS-1 cells in the dogs after 48hours. This corroborates previous studies that also indicated DS-1 cells do not engraft, but are sequestered and cleared in the lung within 48 hours. Given that circulating monocytes express activation antigens within hours of DS-1 infusion and that we previously showed monocytes in contact with this class of fibroblasts express genes associated with multicellular organismal development, we hypothesize that the DS-1 effect is indirect and mediated by monocyte derived activities.
