title: Angiomatosis and ectopic ossification in the dog myocardium after intramyocardial implantation of autologous bone marrow mononuclears in experimental coronary disease.
abstract: Disseminated ossification of the myocardium and severe angiomatosis were detected in sites of implantation of unseparated bone marrow mononuclear fraction cells in dogs with experimental chronic coronary disease. Minor immunocytochemical differences in cells of the mononuclear fraction adhering and not adhering to plastic were found. Significant differences in the expression of mRNA of chondro-osteogenesis genes (aggrecan, lumican, and osteopontin) in adherent and nonadherent cells were detected. The expression of aggrecan gene mRNA was 3-fold lower, of lumican gene 6-fold, and of osteopontin gene 11-fold lower in nonadherent cells compared to adherent fraction.
