Mesenchymal stem cells(MSCs)is a kind of non hematopoietic stem cell from the mesoderm, which can self renew, proliferate and perform multilineage differentiation. Due to the characteristics of acquiring easily and low immunogenicity, it has become the main cell for myocardial infarction. In this article, the biology and the immunology of the MSCs is reviewed, the safety and the validity of the therapy on myocardial infarction with MSCs and the HGF/MSCs is introduced. And furthermore, it also explains the possible mechanism and the problems of how to improve the cardial function.
Dilated cardiomyopathy (DCM) is a highly prevalent disease which has multiple clinical manifestations and pathological features. With the characteristics of multi-sequence and multi-parameter, cardiac magnetic resonance imaging (MRI) can accurately assess the morphology, function and tissue characterization of heart, and provide comprehensive information for diagnosis of DCM. This review focuses on the sequences and clinical applications of MRI evaluation in DCM in order to provide additional information for clinical diagnosis, treatment and prognosis.
