Arodent cardiac side population cell fraction formed clonal spheroids in serum-free medium, which expressed nestin, Musashi-1, and multi-drug resistance transporter gene 1, markers of undifferentiated neural precursor cells. These markers were lost following differentiation, and were replaced by the expression of neuron-, glial-, smooth muscle cell-, or(More)
BACKGROUND We recently reported that cardiomyocytes could be differentiated from bone marrow mesenchymal stem cells in vitro by 5-azacytidine treatment. In native cardiomyocytes, adrenergic and muscarinic receptors play crucial roles in mediating heart rate, conduction velocity, contractility, and cardiac hypertrophy. We investigated whether these receptors(More)
Bone marrow mesenchymal stem cells (CMG cells) are multipotent and can be induced by 5-azacytidine to differentiate into cardiomyocytes. We characterized the electrophysiological properties of these cardiomyocytes and investigated their potential for use as transplantable bio-pacemakers. After differentiation, action potentials in spontaneously beating(More)
When C3H (H-2k, Mls-1b) mice were primed intravenously with 10(8) viable spleen cells from AKR (H-2k, Mls-1a) and treated intraperitoneally with 200 mg/kg of cyclophosphamide (CP) 2 d later, not only a long-lasting skin allograft tolerance but also a tolerance in mixed lymphocyte reaction to Mls-1a-encoded antigens was established. The cellular mechanisms(More)
