Directions for Enhancement of the Therapeutic Efficacy of Mesenchymal Stem Cells in Different Neurodegenerative and Cardiovascular Diseases: Current Status and Future Perspectives.

Mesenchymal stem cells (MSCs) have shown promising therapeutic effects in a wide variety of medical conditions, including neurodegenerative disorders and cardiovascular diseases. Although preliminary research has emphasized the ability of MSCs to engraft at sites of injury, several studies have revealed that MSCs mediate their effects through the release of various paracrine factors and through their antioxidant, anti-inflammatory, immunomodulatory, and anti-apoptotic effects. The clinical implications of MSCs application are limited due to their low survival rate in conditions of inflammation, oxidative stress, and nutrient restriction in damaged areas. Furthermore, the function of isolated MSCs is usually affected by the patient's health. Therefore, it is necessary to develop new methods to enhance the therapeutic efficacy of MSCs under pathophysiological conditions. This review provides an overview of the general properties of MSCs, their therapeutic potential in neurodegenerative disorders such as Alzheimer's disease, Parkinson's disease, multiple sclerosis, amyotrophic lateral sclerosis, and Huntington's disease, as well as cardiovascular diseases such as myocardial infarction, diabetic cardiomyopathy, and dilated cardiomyopathy, and their related mechanisms. In addition, this review also discusses potential problems and side effects, as well as current and future directions for improvement of MSCs therapy and their implications and applications.
