Stem Cells and Heart Disease

Stem Cell Treatments for Heart Disease is an Option

Cardiovascular diseases remain the biggest cause of deaths worldwide, though over the last two decades, cardiovascular mortality rates have declined in many high-income countries but have increased at an astonishingly fast rate in low- and middle-income countries. The percentage of premature deaths from cardiovascular disease range from 4% in high-income countries to 42% in low-income countries. More than 17 million people died from cardiovascular diseases in 2008. Each year, heart disease kills more Americans than cancer. In recent years, cardiovascular risk in women has been increasing and has killed more women than breast cancer.

Measures to prevent cardiovascular disease may include:

  • Keeping unapposed simple carbohydrates under control, no matter what type: fruit, bread, dairy, etc.
  • decrease emotional stress, or how you react to the environment (traffic, work, deadlines, lifestyle, etc.)
  • a low fat high fiber diet including whole grains and plenty of fresh fruit and vegetables (at least five portions a day)
  • a diet high in complex vegetables and colorful fruit
  • tobacco cessation;
  • limit alcohol consumption;
  • lower blood pressures if elevated through diet and exercise;
  • decrease body fat (BMI);
  • increase daily activity to 30 minutes of any kind of exercise per day at least five times per week

A fairly recent emphasis is on the link between low-grade inflammation that hallmarks atherosclerosis and its possible interventions. C-reactive protein (CRP) is a common inflammatory marker that has been found to be present in increased levels in patients at risk for cardiovascular disease. Also osteoprotegerin which is involved with regulation of a key inflammatory transcription factor called NF-κB has been found to be a risk factor of cardiovascular disease and mortality. Studies have shown that Stem Cells have shown the ability to reduce inflammation.

Mechanism of 17β-estradiol stimulated integration of human mesenchymal stem cells in heart tissue. J Mol Cell Cardiol. 2019 Jun 12;: Authors: Mihai MC, Popa MA, Suica VI, Antohe F, Jackson EK, Simionescu M, Dubey RK Abstract Scarcity of gender specific donor hearts highlights the importance of mesenchymal stem cells (MSCs) as a therapeutic tool for heart repair. However, inefficient incorporation, retention, and activity of MSCs in cardiac tissue remain an obstacle. Since surges in follicular estradiol (E2; μmolar-range) trigger tissue remodeling (e.g. ovulation) and E2 exerts beneficial actions on the cardiovascular system, we hypothesized that E2 may promote/improve MSC-mediated cardiac repair processes. Using Wharton's jelly (WJ)-derived MSCs we assessed the effects of E2 on MSC proliferation, directed migration, and engraftment in murine heart slices (using xCELLigence real-time cell-impedance system, DNA quantification, and microscopy) and on MSC-induced angiogenesis in vivo (matrigel plug assay). Protein expression was assessed by Western blotting, ELISA/Luminex, and proteomic analysis; whereas mRNA expression was assessed by qRT-PCR. MSCs expressed estrogen receptors (ERs) -alpha and -beta. E2 promoted MSC proliferation and up-regulated mRNA and protein expression of ER-alpha, ER-beta, extracellular matrix metalloproteinase inducer (EMMPRIN), and matrix metalloproteinase (MMP) -9, yet down-regulated MMP-2 expression. Moreover, E2 up-regulated expression of vascular endothelial growth factor (VEGF)-A, VEGFR-2, vascular cell adhesion protein-1 (VCAM-1), and angiogenin (ANG) and stimulated nitric oxide (NO) production via ER. Proteomic analysis of MSCs showed that E2 up-regulated 47 proteins, down-regulated 7 proteins, and increased the expression of key biochemical components/pathways involved in tissue repair. In MSCs co-cultured with murine heart-slices, E2 significantly induced MSC migration in an ER-alpha-dependent fashion and significantly increased the secretion of MMP-2, MMP-9, ANG, and VEGF. In an in vivo matrigel assay, E2-treated MSCs increased angiogenesis and hemoglobin content. In conclusion, E2-treatment increases the incorporation of MSCs in heart slices and promotes MSC-induced angiogenesis. These beneficial effects are mediated via increases in molecules/pathways involved in tissue remodeling and angiogenesis. We speculate that E2 may enhance MSC ability to repair/regenerate cardiac tissue. PMID: 31201797 [PubMed - as supplied by publisher]
