Can we regenerate heart muscle with stem cells? | Chuck Murry

  • Published on May 2, 2019
  • The heart is one of the least regenerative organs in the human body -- a big factor in making heart failure the number one killer worldwide. What if we could help heart muscle regenerate after injury? Physician and scientist Chuck Murry shares his groundbreaking research into using stem cells to grow new heart cells -- an exciting step towards realizing the awesome promise of stem cells as medicine.

    WOW the implications of this tech can be huge, I'm not an MD but if i understand correctly if it can be used for hurt muscle the basic principle should work for many other damaged organs like lungs, liever, kidneys...

    100 billion dollars every year dealing with the treatment of heart disease? So basically, the people who run the Western Allopathic "Medicine" industry a.k.a. the Pharma-Mafia are so beyond satanically making billions of dollars of the suffering of multitudes of people by convincing them to eat all sorts of food that comes from CAFO operations + processed food everywhere and related like huge amounts of synthetic sugar + GMO etc that affects their health detrimentally instead of morally/ethically and healthy raised animals for food + morally/ethically grown vegetables etc, convince them to drink alcohol to the point of beyond excess, convince them to take all sorts of Pharmaceutical drugs that only treat the symptoms and not the root cause of their health problems and then after convincing the majority of the public to live such a self-destructive lifestyle which they make billions off of, then claim you are going to 'help them' right? People should watch the video "If I Were the Devil" by Paul Harvey" ... it is just absolutely insane how in America.. how corrupt, perverse, immoral, iniquitous it has become.. the population are lab roots for the Pharma-Mafia and Gov't etc and the utterly outrageous diabolist audacity to claim they want to help you.. when if they really did, they would have NEVER convinced you to live such a self-harming lifestyle in which they would further convince you need their pharma-drugs to be ok. They don't make money in the cure, but there are BILLIONS AND BILLIONS of dollars to be made OFF THE SUFFERING OF MYRIADS OF FOOLISH INTELLECTUALLY DULLED DOWN SHEEP! The absolute brazen unconscionable activity of the Western "Medicine" Cartel and all their purveyors and associates, is so beyond words satanic.. and now they are trying to sell you YET ANOTHER way to SPEND / EXTRACT your money from you to have a healthy heart when a total overhaul of the quality of food and drink in America should be made one of the primary focuses of the nation? So satanic how now they are trying to now sell this stem cell heart technology instead of teaching people how to actually live in ways that can make them live past 100 which is known in places in Italy, France, Japan etc.

    Playing God/Jesus with His creation _(mankind)_ in the area of genetic engineering is a form of rebellion which is the utmost offence against the sole Creator, since as explained above, there are folks in southern Italy small towns etc for example who live past 100 and they have very strong hearts for their age and they eat tons of cheese, wine, meat, eggs, salad, veggies etc, and you know why they have such strong hearts? It's because they all the food they eat is locally grown with moral/ethiical standards, no processed foods, everything is made fresh from the land, no harsh chemicals are used etc.. and hence why they need technology like stem cells for heart problems because it's all about how you are eating and living, and if the same type of focus was put on the general diet in America, the ungodly satanic billions of dollars spent per year on the treatment of heart disease.. wouldn't be anywhere what it is now. In other words, rather than the 100+ billion dollar industry really care about you, they care instead to keep feeding you their 'treatments' and drugs etc so are their perpetual lab rat while making you actually think they truly care about getting to the root of the problem and truly healing you.

    All mankind WILL indeed have to face judgement day for the beyond words corruption of the mainline medical INDUSTRY in the West ... and most will end up in the Lake of Fire, why? Because rather than have implemented a health care model that actually taught many non-immigrant Americans to buy food from local farmers who believe in moral/ethical food practices or even to teach the non-immigrant Americans who can do it to learn how to raise, butcher, prepare etc your own chickens, cattle, pigs, making your own cheese etc ike they do in southern Italy so you can live a true healthy life void of processed foods etc, instead, much of the population in America are lab rats for major industry food suppliers to make unimaginable revenue off by getting the people to eat food that isn't much all that real food anymore and hence the skyrocketing health issues ... which is all by design.

    The heart is the least regenerative organ in the body. It heals by scar formation. Stem cells divide very fast, and can turn into any type of tissue, skin, brain, heart etc. By coaxing stem cells to form into heart tissue, we can then inject them into a heart and regenerate the human heart! #TEDTalk

    This is an amazing discovery and has enormous potential. One factor he did not calculate for is human greed. Only those who will be able to afford these treatments from the very few doctors who offer it will get to live. Everyone else who can't pay, has no insurance, or state insurance will continue to suffer and die. Many of these amazing scientific medical break throughs would change our species function and health if distributed to everyone. Governments who rule this world won't allow it.

    • BruceMagnus
      BruceMagnus 3 months ago +1

      Human greed is the reason this technology is even possible. These inventors will make lots of money. The first patients will be the rich who will be able to afford the high price. And as more people do this, it will drive costs down to be affordable for everyone just like computers and smartphones today.
      The rich early adopters effectively subsidize research & development costs for the poor. The promise of big payoffs leads entrepreneurs to take risks in creating these technologies.
      If we had socialism, none of this technology would ever be invented and we would be hundreds of years behind in technology, medicine, science, etc.

    the single most important decision you make on a daily basis is what you put in your mouth. that is where the problem lies. stem cells will not fix arterial plaque, so stop misdirecting everyone away from the source of the problem. vast majority of doctors only treat problems and rarely address the root cause to the detriment of all. That belly fat you are carrying around chuck points to your ignorance.

      As I understand it, stem cells are derived from fertilized eggs, in which the cells have not yet differentiated. They're generally leftovers from in vitro fertilization, and would be discarded if not used this way. The donors must give permission for their fertilized eggs to be used, rather than destroyed.

    Interesting research, good job! Stem cells have so much potential and they should definitely be researched more. They are especially interesting because in many cases they could be collected from the same person who is going to be the recipient of the graft, minimizing the possibility of rejection. The lack of a compatible donor would not be such a big issue anymore.

  • Val Taylor

    He’s describing corrective action. Preventive action also has to be included. Deficiency most likely led to the disease condition. There’s way too much technology and science supporting what causes inflammation of the heart.

    • Val Taylor

      Tim N thanks for your response! The story the doctor shared about his mother summarized her life as a “healthy” woman who was active and full of life. Then one day, she had an event that in essence signaled the beginning of the end of her life. She had no knowledge of her CAC score. He doesn’t describe what dietary practices that she followed that was the precursor of the event. I thinks it’s awesome that his research developed a technology that can help many people after a cardiac event. My point of emphasis is that let’s provide the body with what it needs and then see how long it can sustain vibrance, productivity and longevity. We already know there’s a pandemic occurrence of diabetes not only in this country but around the world. Whether it’s insulin resistance, pre-diabetes or type II, people are addicted to refined carbs. The health of the individual begins to breakdown from there. There is too much scientific evidence now in the main stream that contradicts the guidelines of nutrition outlined in the early 90’s. Cause and effect or more accurately......action and result. If interested and aren’t already familiar, Jeffrey Dach has a ton of great info on prevention and reversal of heart disease.

    • Tim N

      You are correct. However, many complex and severe diseases are both genetic and environmental. In essence, they are multi-factorial. Recent advances and research shows that both genetic and preventative medicine is equally responsible, so it is illogical to conclude that this will only benefit very few people.

      Examples of complex diseases are diabetes and cancer. While preventative medicine is a strongly supported case with lots of evidence, something that should be emphasized with great importance, the genetic and cellular factors are the other side of the coin. Together, you need both to effectively diagnose, treat, and prevent heart disease. For patients who are genetically healthy, if environmental factors prompt them to have increased risk in heart disease, then therapies alluded to by Dr. Murray will come into play. However, if patients are observed to have genetic dispositions that are associated with greater risk of heart disease, then preventative medicine (such as eating healthy and getting proper exercise) is not fully sufficient. However, gene therapy (replacing bad genetic markers associated with disease with the healthy genetic components) is on the rise. By knowing the genetics of what makes heart disease greater in risk, we are able to treat it so that preventive medicine may be fully effective--and thus, truly preventative.

      His contributions are not only an example of innovative and pioneering work on understanding and translating biomedical science, but also helping us fulfill the other side of the coin that is necessary for truly combating heart disease.
