Task: Answer Verification
Input (English): Question: Do 5-Azacytidine-treated human mesenchymal stem/progenitor cells derived from umbilical cord , cord blood and bone marrow generate cardiomyocytes in vitro at high frequencies?
Answer: Although MSCs may be useful for such clinical applications as bone or cartilage repair, the results presented here indicate that such cells do not generate cardiomyocytes frequently enough for cardiac repair. Their efficacy in heart repair is likely to be due to paracrine mechanisms.
Output (English): no
