Maybe you’ve known someone who is in need of an organ transplant. In a situation where time is of the essence, the weight can be painful. If you’re even lucky to get an organ donated at all. This may become a thing of the past. Researchers have just made a breakthrough by 3D printing a heart from real human cells. This is one step closer to a future where 3D organs. Since the 800 scientists have developed vaccines and medicines by growing cells in glass Petri dishes. It was instrumental in advancing biological science for the past few centuries. In recent years, with the advent of 3D printing, the two D petri dish has now been upgraded to another dimension.
A revolution has started to develop organs for transplants in the lab. Researchers at Israel’s Tel Aviv University have just successfully 3D printed a heart made from real human cells. Previously, this was only achieved with non-organic materials such as Silicon. The odd incredible potential breakthrough in making organs. In a lab, Israeli researchers have printed a 3D heart, complete with muscle and blood vessels. He explained that the cells that made the heart came from a donor’s fat tissue, which is then transformed into embryonic stem cells and then differentiated into the various cell types in the heart. The heart is small, only about the size of a rabbit’s heart. However, researchers were able to create Chambers and veins. The researchers envision creating 3D printed hearts suitable for human transplants and also patches that can regenerate defective tissue.
Professor Dever, who led the project, stated, this was the first time anyone anywhere has successfully engineered and printed an entire heart replete with cells, blood vessels, and printed an entire heart replete with cells, blood vessels, With that being said, some obstacles still stand in the way. While the cells can contract, they do not possess the ability to pump, which is the research’s next objective. But there are still many advantages in comparison to traditional organ transplants to be optimistic about normally in organ transplants, the body may reject an incoming organ. This is due to the immune system sensing antigens in the cells of the organ, which did not match the rest of the body cells.
For kidneys, about 25% of transplant patients experience an episode of severe rejection in the first year of the transplant, and for heart transplants, that number rises to 40%. But this 3D printed heart uses human tissue as the bio-ink.
Here’s how it works, A sample of cells can be taken from the patient, and a 3D organ can be printed with a personal hydrogel made from their own cells. This potentially resolves rejection issues. This isn’t the first time researchers have printed a heart in 2017 scientists and Zurich, Switzerland. 3D printed an artificial heart, but instead of using human tissue, they were only able to achieve the feet. Using soft, flexible Silicon material, the heart was able to push and pull water through intricate chambers at a rate of 80 beats per minute. However, it was only able to pump for 3,000 beats in a row or approximately half an hour.
The zero cart was able to achieve a pump flow of 2.2 litres per minute. This is about two to 3 times less than the human heart, still far from what’s required to keep a human alive. But not bad for a replica.
Apart from the application of building replacement organs, 3D printing is being used to develop new medicines. For example, what if, rather than being given a one size fits all medication, doctors and scientists can model your illness and apply the right exact procedure or medicine for your case by building tumours and labs using 3D printing, researchers are attempting to do just that.
A team at McMaster University in Canada have developed a rapid magnetic 3D by printing system, which can build a replica of a cancerous tumour in as little as six hours. The idea is then to test different drugs and treatments, changing the dosage and frequency to see which one works best. Then, after the lab testing, the patient would be given a tailormade medication program. This could decrease side effects and more importantly, increase the chances of survival for the patient. So this recent breakthrough of 3D printing a heart with real human cells foreshadows a future where OnDemand organs are available without waiting lists. are available without waiting lists. a decade away. For all of this raises some interesting questions for human life, How much longer could we extend our lives if we easily could replace body parts? Would most people want to do that? And what about the price of a new heart? Will everyone is able to afford it? At first?
Predictably, such technology might only be available to the rich, but in the future, prices may come down far enough so that the technology could be cheap and routine. And after this, what comes next? High capacity lungs that can provide oxygen more efficiently, or heart attack proof hearts that are resistant to failure.
The future of biotech is interesting perhaps the next big revolution will be the upgrading of perhaps the next big revolution will be the upgrading of So what’s your opinion on such a future? So what’s your opinion on such a future? or does this kind of thing bother you? And should we let nature take its course?
