Heart failure affects more than 25million people every year. Out of them hardly 20-30% people are able to get a heart transplant. That means most of the people suffering from heart failure won’t get a new one for survival. But there is a good news for them or atleast a ray of hope.
Scientists from Massachusetts General Hospital and Harvard Medical school grew a heart using stem cells then shocked it with an electric current to bring it to life.
In addition, researchers from Tel Aviv University have “printed” the world’s first 3D vascularized engineered heart using a patient’s own cells.
This all is done by using the Skin cells and around 73 donor hearts which were deemed unfit for the transplantation.
This is how it was done:
They first converted the skin cells into the pluripotent stem cells, then made them transform into two types of cardiac cells.
Next, they mimicked the environment a human heart would typically grow within and infused the cardiac cells with a nutrient solution that facilitated growth. They left the cells there for two weeks.
After the two weeks, they shocked the hearts with electricity and it began beating.
The study has been published in Circulation Research.
In another achievement, scientists at Tel Aviv University printed world’s first 3D heart which completely matches the biological properties of the patient who donated the cells.
In statement, they said –
“This is the first time anyone anywhere has successfully engineered and printed an entire heart replete with cells, blood vessels, ventricles and chambers…This heart is made from human cells and patient-specific biological materials. In our process these materials serve as the bioinks, substances made of sugars and proteins that can be used for 3D printing of complex tissue models. People have managed to 3D-print the structure of a heart in the past, but not with cells or with blood vessels. Our results demonstrate the potential of our approach for engineering personalized tissue and organ replacement in the future… At this stage, our 3D heart is small, the size of a rabbit’s heart. But larger human hearts require the same technology.”
The goal is to eventually grow an entire human heart that is capable of being transplanted.
Title – A title can be anything from a question, a heading of the article, or even the main topic about which you are publishing the post.
Description – It is explaining and adding the details about the topic you are posting. If you are asking a Question, then adding details is not necessary.
Photo, Video – You can attach a photo related to your post or can even publish a YOUTUBE video.
Sharing – Your name gets automatically attached behind the title of the article when you share is on Facebook or other platforms.
Eg: If a user John Watson have posted an article with the Title “How to handle Migraine without medicines?” and then if anyone share it on Facebook, the title will be like this :
“How to handle Migraine without medicines?”- John Watson
Themes of publishing or asking – You can publish from various themes that we mentioned and if any topic is missing among them, you can still post anything related to the Health. Healthcare is the only broad theme.
This data changes rapidly, so what’s shown may be out of date. Table totals may not always represent an accurate sum. Information about reported cases is also available on the World Health Organisation site.
It doesn’t include all cases
Confirmed cases aren’t all cases. They only include people who tested positive. Testing rules and availability vary by country.
