Myocardial infarction is the leading cause of morbidity and mortality worldwide. Recent advances in cardiac regenerative therapy have allowed for novel modalities in replenishing the damaged myocardium. However, poor long-term engraftment and survival of transplanted cells have largely precluded effective ...

Stem cell transplantation therapy is a promising adjunct for regenerating damaged heart tissue; however, only modest improvements in cardiac function have been observed due to poor survival of transplanted cells in the ischemic heart. Therefore, there remains an unmet need ...

Naturally secreted nanovesicles known as exosomes are required for the regenerative effects of cardiosphere-derived cells (CDCs), and exosomes mimic the benefits of CDCs in rodents. Nevertheless, exosomes have not been studied in a translationally realistic large-animal model. Researchers from Cedars-Sinai ...

To regenerate heart tissue after a myocardial infarction, researchers have investigated cell therapies involving cardiac progenitor cells. These cells can differentiate into heart cells such as cardiac myocytes, endothelial cells and fibroblasts, but it is not clear whether this differentiation ...

Telocytes have been reported to play an important role in long-distance heterocellular communication in normal and diseased heart, both through direct contact (atypical junctions), as well as by releasing extracellular vesicles (EVs) which may act as paracrine mediators. Exosomes and ...

The heart is an organ with a complex mixture of well-organized interactions of different cell types that facilitate proper myocardial contractility, sufficient perfusion, balanced myocardial extracellular stiffness, and controlled functioning of the immune system. Several cell types, including cardiomyocytes, endothelial ...
Read More »Protecting the Heart at a Distance: Exosomes for nano-sized Cardioprotection
Preconditioning is widely known to protect cardiomyocytes from reperfusion-induced cell death by activation of several pro-survival transductional pathways. The fact that preconditioning can be achieved remotely (Remote Ischaemic Preconditioning, RIPC) means that humoral factors are released from ischaemic limbs into ...
