What is fetal microquimerism?

Some fantastic narratives sometimes gain character even in less scary and allegorically. Meanwhile, you can at least meet a few kimer in the micro version.

The word Chimera has gained different meanings over the years, used as a representation of ‘opponents’ or showing a certain heterogeneity among things in artistic works or people.

If you have an entrance exam or already, you may have read Ana Miranda’s novel ‘The Last Chimera’, who tells the story of Augusto Dos Anjos, the author of a biographical book poem.

However, in addition to mythology and literature, another issue accused of entrance exams is genetic. So today you will learn some more about the wonders and features of this field of biology. What kind of microquimera can you make your mother.

What is Chimera?

Chimera is an organism with a genetic set that exists at least two different together, So a person with two DNA. This is very rare and records indicate only 100 approved cases in humans.

But only people cannot offer chimerism. Anything that has a genetic material, including animals, plants and some RNA viruses, may suffer from this strange combination.

This genetic condition may occur in different ways caused by natural or artificial processes. Sometimes this ‘Kimerik Situation’ is only temporary depending on how the chimer occurs, some, no.

Eternal chimles also occur during the zygote formation phase or in embryonic and fetal phases. In parthenogenetic chemical, one egg can be fertilized by two sperm. However, due to extra genetic load, eggs do not pull the meiosis and as a result does not produce grandchildren that can survive.

Already in the tetragametic chimney, things come out in a more complex but applicable way. In this phenomenon, two eggs are fertilized with a sperm. However, instead of producing twins, zygotees mix their genetic loads and produce a single individual..

Different DNA cells can focus on different regions, such as being responsible for lung or blood formation, for example. Another with the same situation can be a combination that provides unique epithelial properties, such as having a body, arms or legs of different colors than the rest of the body.

Mixtures and combinations can be varied and even invisible, What makes it difficult to find people with chimerismSince this is a strange combination between different DNA, there is no serious health reflection as much as it is known.

A kimera may also occur during inactivity pregnancies, which stops development, where one of the twins absorbs the cells of his brother. However, there is a cell acquisition that does not take the absorption of the parts of the other brother, covers DNA, and mixed with them.

In this complex relationship between the twins, there may also be blood chimerism in which the transmission of vessels between sister twins can produce some kind of transfusion with permanent effects.

Apart from common types, A, B, O, EU, Chimeras may also have OA blood or OB in different proportions. These will be conditions to create a complete, permanent and rare kimera! But there are other ways to be Kimera.

How can I know if I am Chimera?

You will need to be subjected to genetic tests to find out if you are a complete Kimera.
You are wondering about Chimeras’s rareness that this reality may change with the explosion of genetic tests, but the answer is no.

Knowing if a person is Kimera, DNA of different parts of the body and blood.

Do you remember saying that different DNA can be allocated to only a part of the body? For this reason, ‘homemade’ tests cannot detect a kimera because it will only collect and test the example of a region.

This specificity has been the subject of legal debate in cases where birth can only be proved through uterine DNA. Every rest was contradiction.
However, there is also a temporary Kimera in birth and paternity tests without fear of mistakes. If you are a mother, you got an organ donation or you made bone marrow transplantation, you are probably you or it was a microquimera.

Microquimerism, what is it?

Microquimerism is natural or artificial where there is a small amount of different DNA cells in the body.. Although the exact chimles are rare, it is believed that microquimers are very common. Even if this temporality stretches for decades, you have made your mother a temporary microquimera.

Studies have shown that some fetal cells during pregnancy can be circulated in the body of the woman. According to some studies, these cells may have beneficial effects and mechanics on the organisms of the genitors.

In contrast, in the long run, the same ‘strange’ DNA cells can be attributed to the development of autoimmune diseases, because in order to reduce the effects of this fetal heritage, the body will fight without distinguishing the real one. targets.

One curiosity is that thanks to the discovery of microquimerism, tests such as fetal and nipt investigating syndromes and other genetic conditions are possible, because these tests analyze the presence of fetal cells in the material bloodstream.

Believed New fetal cells can be left as a temporary heritage during each pregnancyIt can be disintegrated months after the birth of the baby, but there have been reports for decades.

The existing fetal cells in the mother’s body seem to not interfere with other pregnancies because the placenta that manages the mother-baby relationship is unique to each child.

Other tools of being a temporary microquimera are intake of organs, bone marrow transplantation and less frequent blood intake. Apart from transplantation, our organisms in other conditions realize that renewal and hereditary cells exist.

There is a lot of research with micro -interlocutors and the impact of the inclusion of this DNA, only initially and in this interesting genetic field, there is much that people find more Chimeras than the health results. Genetic properties that require attention.
