Stem Cell Treatments for Heart Disease is an Option

Stem Cell Treatment for Heart Disease

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

Stem Cell Heart Disease

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.

Thioredoxin mitigates radiation-induced hematopoietic stem cell injury in mice. Stem Cell Res Ther. 2017 Nov 15;8(1):263 Authors: Sundaramoorthy P, Wang Q, Zheng Z, Jiao Y, Chen BJ, Doan PL, Chao NJ, Kang Y Abstract BACKGROUND: Radiation exposure poses a significant threat to public health. Hematopoietic injury is one of the major manifestations of acute radiation sickness. Protection and/or mitigation of hematopoietic stem cells (HSCs) from radiation injury is an important goal in the development of medical countermeasure agents (MCM). We recently identified thioredoxin (TXN) as a novel molecule that has marked protective and proliferative effects on HSCs. In the current study, we investigated the effectiveness of TXN in rescuing mice from a lethal dose of total body radiation (TBI) and in enhancing hematopoietic reconstitution following a lethal dose of irradiation. METHODS: We used in-vivo and in-vitro methods to understand the biological and molecular mechanisms of TXN on radiation mitigation. BABL/c mice were used for the survival study and a flow cytometer was used to quantify the HSC population and cell senescence. A hematology analyzer was used for the peripheral blood cell count, including white blood cells (WBCs), red blood cells (RBCs), hemoglobin, and platelets. Colony forming unit (CFU) assay was used to study the colongenic function of HSCs. Hematoxylin and eosin staining was used to determine the bone marrow cellularity. Senescence-associated β-galactosidase assay was used for cell senescence. Western blot analysis was used to evaluate the DNA damage and senescence protein expression. Immunofluorescence staining was used to measure the expression of γ-H2AX foci for DNA damage. RESULTS: We found that administration of TXN 24 h following irradiation significantly mitigates BALB/c mice from TBI-induced death: 70% of TXN-treated mice survived, whereas only 25% of saline-treated mice survived. TXN administration led to enhanced recovery of peripheral blood cell counts, bone marrow cellularity, and HSC population as measured by c-Kit(+)Sca-1(+)Lin(-) (KSL) cells, SLAM + KSL cells and CFUs. TXN treatment reduced cell senescence and radiation-induced double-strand DNA breaks in both murine bone marrow lineage-negative (Lin(-)) cells and primary fibroblasts. Furthermore, TXN decreased the expression of p16 and phosphorylated p38. Our data suggest that TXN modulates diverse cellular processes of HSCs. CONCLUSIONS: Administration of TXN 24 h following irradiation mitigates radiation-induced lethality. To the best of our knowledge, this is the first report demonstrating that TXN reduces radiation-induced lethality. TXN shows potential utility in the mitigation of radiation-induced hematopoietic injury. PMID: 29141658 [PubMed - in process]
