Scientists Just Transplanted Lab-Grown Lungs into Pigs

Scientists from the University of Texas Medical Branch just successfully transplanted lab-grown lungs into pigs – an exciting development towards being able to bioengineer lungs for humans someday, too. To create these lungs, researchers first made a lung skeleton. They used sugar and detergent to remove the cells and blood from pig lungs, leaving them with a protein structure. Next, scientists added cells from the recipient pig lungs to each scaffold, and let them grow over 30 days. When the lungs were ready, they made the transplant into four recipient pigs. 

Within two weeks, the transplanted lugs began to develop the blood vessel networks they need to survive. The animals seemed to take their lab-grown lungs well, showing no signs of rejecting the foreign organs. Researchers will continue to study the effects of the transplanted organs long term. If their work is successful, it could change organ transplation in the future. Currently, there’s over 1,400 people in the U.S. 

awaiting lung transplants. Researchers believe they could be five to ten years away from being able to transplant lab-grown lungs to patients in compassionate use circumstances. Bioengineered organs could be an improvement from human donated organs: lungs grow from the recipient’s own cells are less likely to get rejected by the body, and being able to grow new lungs in a lab could put an end to organ shortages.

Genetically modified pigs able to resist costly disease – Scientific Inquirer

Scientists have produced pigs that can resist one of the world’s most costly animal diseases, by changing their genetic code. Tests with the virus – called Porcine Reproductive and Respiratory Syndrome, or PRRS – found the pigs do not become infected at all. The animals show no signs that the change in their DNA has had any other impact on their health or wellbeing. The disease causes breathing problems and deaths in young animals and if pregnant sows become infected, it can cause them to lose their litter. The virus infects pigs using a receptor on their cells’ surface called CD163. 

The team collaborated with Genus PLC, a leading global animal genetics company, to produce pigs with the specific DNA change. Previous studies had shown that cells from these animals were resistant to the virus in lab tests. This is the first time researchers have exposed these pigs to the virus to see if they become infected. Other groups have used gene editing to create PRRS-resistant pigs by removing the whole CD163 receptor. Genetically modified animals are banned from the food chain in Europe. 

It is not clear what regulations would apply to gene-edited animals as the approach is different. GM techniques have been controversial because they can involve introducing genes of other species into an animal.

Tea cup pigs? Here’s the truth from Pete the Vet on TV3’s Ireland AM

A baby pig pet sounds so charming, and the idea of a pig that never gets much bigger than a small dog sounds interesting. Pigs are at least as intelligent as dogs, and they often have huge personalities. The truth is that there’s no such things as pigs which stay the size of a teacup. A large, boisterous animal like this is a complex creature to have living living in. For this reason, many people get cute piglets only to discover that it’s impossible to keep them as they grow older and bigger, and they have to rehome them. 

Pigs are social, playful, protective animals who love the company of their own species, and they love to be outside, playing, rooting around in woodland, engaging with their environment. You also need to consider legal aspects: as farm animals, pigs are tightly regulated, including travel, living conditions and other issues. You may also struggle to find a vet who is experienced in treating pigs as pets.

‘Broke My Heart’: Pup Mourns The Death Of Guinea Pig Best Friend « CBS Chicago

WACO, Texas – A dog’s touching farewell to his best friend is breaking hearts on social media. According to multiple reports, Joseph Scaramucci posted several pictures on Facebook of his pup Mattis, who was clearly heartbroken over the death of the family’s guinea pig. Otis the guinea pig reportedly died on July 28 after the family returned from vacation. Brittany Scaramucci told local reporters Mattis refused to leave his best friend’s side until his passed over the weekend. The Scaramuccis report that Mattis is still mourning the loss of his friend of four years. 

The depressed canine probably shouldn’t surprise anyone. A 2014 study found that dogs pick up on emotions the same way humans do, so Mattis’ touching display for his dying friend was more natural than some might think.
