To utilize a novel type of polymer-drug conjugate micelle to enhance the delivery of low-potency curcumin. Multiple curcumin molecules were conjugated to poly(lactic acid) (PLA) via tris(hydroxymethyl)aminomethane (Tris) linker producing the hydrophobic drug-binding block; methoxy-poly(ethylene glycol) (mPEG) was employed as the hydrophilic block. Micelles(More)
The differentiated cell lineages from human embryonic stem cells (hESCs) and human induced pluripotent stem cells (hiPSCs) have shown their potential in regenerative medicine. However, the functional and transcriptional microRNA (miRNA) expression pattern during endothelial differentiation has yet to be characterized. In this study, hESCs and hiPSCs were(More)
Animal models that mimic cardiovascular diseases are indispensable tools for understanding the mechanisms underlying the diseases at the cellular and molecular level. This review focuses on various methods in preclinical research to create small animal models of cardiac diseases, such as myocardial infarction, dilated cardiomyopathy, heart failure,(More)
Matrigel promotes angiogenesis in the myocardium from ischemic injury and prevents remodelling of the left ventricle. We assessed the therapeutic efficacy of intracardiac matrigel injection and matrigel-mediated stem cell homing in a rat myocardial infarction (MI) model. Following MI, matrigel (250 μl) or phosphate-buffered solution (PBS) was delivered by(More)
Metformin is one of the most widely prescribed antidiabetics for type 2 diabetes. A critical role of metformin against tumorigenesis has recently been implicated, although several studies also reported the lack of anticancer property of the antidiabetics. Given the controversies regarding the potential role of metformin against tumour progression, the(More)
BACKGROUND Bone marrow (BM) stem cells have been reported to contribute to tissue repair after kidney injury model. However, there is no direct evidence so far that BM cells can trans-differentiate into renal stem cells. METHODS To investigate whether BM stem cells contribute to repopulate the renal stem cell pool, we transplanted BM cells from transgenic(More)
Phage display technology has been demonstrated to be a powerful tool for screening useful ligands that are capable of specifically binding to biomarkers on the surface of tumor cells. The ligands found by this technique, such as peptides, have been successfully applied in the fields of early cancer diagnostics and chemotherapy. In this study, a novel(More)
The low cell engraftment after transplantation limits the successful application of stem cell therapy and the exact pathway leading to acute donor cell death following transplantation is still unknown. Here we investigated if processes involved in cell preparation could initiate downregulation of adhesion-related survival signals, and further affect cell(More)
BACKGROUND One of the most frequently used and efficient suicide gene therapies for prostate cancer is HSV-TK/GCV system, but its application has been limited due to lack of favorable gene vector and the reduction of "bystander effect". We investigated the effect of a novel combination of HSV-TK/GCV fused with Cx43 and gemcitabine using non-viral vector(More)
