Can a needle covered patch heal a damaged heart?

Wow!!!
Now, an international team of researchers thinks it’s found a solution: a tiny patch covered in microneedles that deliver the stem cells directly into heart tissue.

Hearty Animals
To see if their patch might be an improvement on existing delivery methods, such as direct muscle injection or intravascular infusion, the researchers tested it on both rats and pigs, a process they describe in a paper published in Science Advances on Wednesday.


First, they induced the animals to have heart attacks. Then they placed versions of the patches containing cardiac stem cells directly onto some of the animals’ damaged hearts during open heart surgery.

When they later examined the animals’ hearts, they found that those of the rats that received the patches exhibited less cell death as well as the development of new heart tissue. Meanwhile, the treated pigs’ hearts pumped out more blood than the hearts of untreated pigs.

The Big Time
Before testing their patch in humans, the researchers want to replace its polymer base with something that will dissolve in the body, researcher Ke Cheng told Science News. They’re also hoping to figure out an implantation method that wouldn’t require open-heart surgery.

Of course, success in animal testing doesn’t always indicate that a treatment will work in humans. Still, if the patch does produce the same results in human trials as it did in animal ones, the tiny device could one day be a game-changing — and potentially life-saving — cardiac therapy.

I agree... Wow!
That sounds really good.
Heart attacks are still one of the biggest killers, and even when people survive the initial attack, their hearts are damaged and they're much more likely to have another.
This could change all of that and save many lives. I hope they get the same or better results in human trials.
