Li et al (27) reported a localization of cardiac troponin T (cTnT) in DAPI-labeled B-cell lymphoma-2-transduced MSCs in a rat model of irreversible ligation of the left anterior descending coronary artery, indicating differentiation towards cardiomyocyte-like cells. This evidence concerns the gene TNNT2 and B-cell non-Hodgkin lymphoma.
