Miracle Injection Regrows Blood Vessels To Cure Heart-Disease

Researchers have demonstrated a new and effective method to regrow blood vessels in the heart and limbs.

This has formed major implications for how we can treat heart disease which is the main cause of death in the western world due to bad dieting, smoking & a lack of exercise.  This method is achieve by injecting a lipid-incased substance into a patient. Once inside the body, the substance stimulates cell growth of new blood vessels from pre-existing ones, including those lost from a heart disease. It has been tested successfully on rats and the studies were published in the Proceedings of the National Academy of Sciences.

The method was developed Aaron Baker who is an assistant professor in the Department of Biomedical Engineering. He said

 “Our method basically delivers extra components that can restore growth factor responsiveness to the tissue of patients with long-standing clinical disease.”

The following video shows the blood vessels growing (speeded up).

The new treatment can be proven crucial to save lives. Chronic myocardial ischemia disease affects up to 27 million patients in the United States alone. The disease reduces blood flow in the heart and lower limbs,ultimately causing organ dysfunction and failure. However the new treatment is said to most probably be able to cure this disease though producing this treatment and then stocking it in the market may cost a lot. Therefore countries in the third world or in poverty will most likely have less access to this cure – another example of the harsh reality between the gap of the rich and the poor which only seems to be becoming wider. Doctors have treated ischemia by physically opening the closed artery with a stent or surgically rerouting blood flow to the damaged tissue. However this method has limitations as well as not being effective in the long-term.

In recent times, the challenge for scientists as well as chemical engineers has been to bind specific substances with cell receptors – the molecules  found on the surface of the cell that receive chemical signals and control activities in the cell from outside sources. Baker’s method creates the growth factors in synthetic lipid-based nanoparticles. The nanoparticles contain receptors that, when delivered with the growth factor, improve cell binding so that the growth factor can direct the targeted cell to divide and form new cells. This results in blood vessel growth.

As years go by science seems to surprise with what seemed a miracle 10 years. Makes me wonder what science has for us in the years to come. Only time will tell.

  1. Wow, that’s super cool. Thanks for posting!

  2. Interesting article. If the drug is given systemically, you’d have to wonder about unwanted angiogenic effects, like malignancy. That said, it would be very interesting treatment if used locally in the coronaries themselves to encourage collaterals…

  3. Nicole “Hoopz” Alexander is not only known for being Flav’s favorite pick in season one of Flavor of Love, but she’s also one of a handful of female celebrities part of a sex tape video scandal, which showed her and her boyfriend at
    the time together. It is a normal progression that more and more people
    are now being turned on to the idea of hookah houses for
    exotic tobacco blends which merge bold tobacco leaves with
    fruit and other flavors for a exceptional flavor. Don’t forget to get a carrying case if you’ll
    need it, extra rubber stoppers and, of course, hookah tobacco.
