Scientists Grow Full-Sized Human Heart In Lab Using Stem Cells 

Each year, there are nearly 4,000 Americans awaiting heart transplants but only 2,000 of them receive hearts. What happens to the others? Of course, they pass away.

Even if a patient receives a heart, there are various complications and the body can also throw off an auto-immune reaction which could result in the body's own cells damaging the new heart tissue. 

To figure out this problem, researchers and scientists have been trying to use patient's own body cells to create different organs of the body. And the great news is, they made it happen up to some extent.

They've been able to get one step closer to making a synthetically created human heart using adult stem cells. 

Only skin cells are used to create this heart.

Human adult skin cells were used in regenerating a functional human heart. It could prove to be very useful for patients diagnosed with heart failure. 

The study on this has been recently published in the Circulation Research journal.

This is the best that scientists could do without setting off an auto-immune response in the whole body. 

Earlier, they used mice as donors.

But that didn't work out and they rejected 73 donor hearts. Later, they tried out adult skin cells with the help of a new technique. 

They changed the RNA pattern of the skin cells.

They modified the messenger RNA of the adult skin cells and turned them into pluripotent stem cells. These stem cells can take the shape of any human cell belonging to any organ of the body. 

Then they infused 2 variants of cardiac cells into it.

After infusing the stem cells with the cardiac cells, a nutrient solution was given to the cells for nearly 2 weeks. The scientists started noticing an immature structure of the human heart was forming. 

The heart was given electric shocks.

The scientists wanted to start the regular rhythm of the heart so electric shocks were passed to make it beat.

Scientists are making more modifications.

Although, the structure of the heart is ready but they aren't sure of the heart being functionally fit to be transplanted. The scientists are making a few changes to make it better. 

But there is good news.

If this technique becomes fully successful, it would be a revolutionary achievement.
