Building a new strategy for treating heart failure using Induced Pluripotent Stem Cells

Journal of cardiology

Abstract

Although cell therapy using myoblasts, bone marrow cells, or other stem cells appears to improve functional recovery of the failing heart, mainly by cytokine paracrine effects, its effectiveness in severely damaged myocardium is limited, probably because there are too few residual myocytes to promote cytokine-induced angiogenesis. Recently, cardiogenic stem cells, such as c-kit-positive cells, were reported to generate cardiomyogenic lineages, and basic research experiments showed that implanting these cells, which can differentiate into cardiomyocytes, improves heart function. However, this functional recovery may have also mainly depended on cytokine paracrine effects, because the differentiation to cardiomyocytes in vivo was poor. In contrast, while Induced Pluripotent Stem Cell-derived cardiomyocytes have paracrine effects, they also have the potential to supply newly born myocytes that can function synchronously with the recipient myocardium as "mechanically working cells" in severely damaged myocardium. Thus, they could represent a "true" myocardial regeneration therapy that can actually regenerate severely damaged myocardium. In addition, iPS cells, especially disease-specific iPS cells, have other applications in regene...Continue Reading

Adult Stem Cells

Adult stem cells reside in unique niches that provide vital cues for their survival, self-renewal, and differentiation. They hold great promise for use in tissue repair and regeneration as a novel therapeutic strategies. Here is the latest research.

CREs: Gene & Cell Therapy

Gene and cell therapy advances have shown promising outcomes for several diseases. The role of cis-regulatory elements (CREs) is crucial in the design of gene therapy vectors. Here is the latest research on CREs in gene and cell therapy.

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.
