American scientists have developed a technology for growing cells of the human immune system in the body of pig embryos. According to the researchers, in the future, the cells obtained in this way may form the basis for new methods of treating cancer and immunodeficiency states
In a study conducted by a team at the University of Michigan led by Jeffrey Platt, researchers injected T-lymphocyte progenitor cells from the bone marrow of donor pig embryos. The immature immune system of embryos did not perceive human cells as foreign, so they could multiply unhindered in their body, differentiating into various types of mature T-lymphocytes.
By mixing human cells isolated from the blood of newborn piglets with the blood of donors, scientists have found that they still perceive donor cells as their own and peacefully coexist with them. At the same time, T-lymphocytes obtained from piglets attacked cells of other people as foreign.
If newborn pigs received vaccinations against viral and bacterial infections, lymphocytes isolated from their blood destroyed the corresponding types of pathogenic microbes.
According to the authors of the study, the method they proposed for growing cells of the human immune system opens up the possibility for new ways to combat various immunodeficiency conditions. In addition, it will be possible to grow T-lymphocytes in the piglets' bodies for immunotherapy of oncological diseases.
Finally, in the same way, you can get immune cells to fight dangerous infections, such as HIV, in the event that existing vaccines are poorly tolerated by a person or do not interact quickly with his immune system.

By the way, pigs are much closer to people than monkeys

A pig is anatomically similar to a human. Pig physiology is most consistent with human. It is not without reason that pig organs are used to transplant liver, kidney, spleen, and even heart to humans. They are much more suitable for transplantation than analogous primate organs. In addition, monkeys are carriers of many infections.
According to some scientists, we caught AIDS through a series of unsuccessful monkey transplants in the 60s. It is much easier with pigs - they can be grown absolutely sterile.
The problem of tissue incompatibility is practically solved. It is enough to raise the number of transgenic pigs. To do this, two human genes are introduced into a pig embryo and one pig gene is "turned off" (to the attention of evolutionists: deliberate shutdown with the participation of smart people is not an accidental positive mutation from the addition of genetic information). The organs of such animals will take root and will work well in the human body.
There are far-reaching plans for use as surrogate mothers for carrying human embryos for sows. Such experiments are already being carried out in many countries of the world … In China, the USA, babies were born, which were carried by a pig (I have not yet found the materials on this case, editor's note).
The pregnancy was proceeding normally. The pigs were given special drugs to prevent the onset of labor, as pigs have a shorter gestation period. At the end of the ninth month, the pigs underwent a caesarean section: the baby's head was larger than the pig's birth canal. A slight jaundice was the only nuisance that accompanied the birth of babies.
This situation is analogous to the Rh-conflict between mother and child in a normal pregnancy. It is caused by the fact that in the body of the child, the bone marrow begins to produce its own red blood cells. There are no special biological obstacles for the widespread introduction of this method of birth of people into the world. There are only ethical obstacles: is it good that the child will have a surrogate mother - a pig?
In France, every year a pig-loving holiday with exciting competitions is held. The winner gets a prize - a roasted pig. However, to turn into a pig you don't have to wait long for the holiday, you can become a pig at any time.
It may well be that the pigs originally had a human appearance and walked on two legs like people … On the island of Madagascar, fossil skeletons of large pig-headed lemurs - Megaladapis were found. However, instead of hooves, these two-meter lemurs had a five-toed "human" hand.
To move in the intricacies of vines, trunks and branches, megaladapis retained grasping hands. Madagascar has been isolated from the mainland for nearly 100 million years. Nothing prevented the ancient Mesozoic people from quietly and peacefully transforming towards brutality.
To make it easier for them to run, they have grown hooves … The embryo of a modern pig, being in the womb of its mother, has a five-fingered hand and a muzzle similar to that of a primate. This may indicate that once upon a time the ancestors of pigs were primates and even humans …
