Ana Sandra solely has the genetic make-up of the sperm donor (Aless Lequio) and the nameless egg donor. It is studied how pregnant moms transmit proteins and vitality to the embryo that may “epigenetically” modify the newborn We recall the conclusions reached by a current examine of the INCLIVA Health Research Institute
The little woman, born on March 20 in Miami, solely has a genetic load from Aless, the sperm donor, and from her organic mom, the egg donor, whose id is secret. So that sooner or later, it’s logical that Ana Sandra solely inherits traits from her organic mother and father. As we’ve already defined, the surrogate being pregnant companies within the United States don’t enable the surrogate mom to be the egg donor, to keep away from any emotional attachment to the newborn when delivering it to its adoptive mom, on this case, Ana Obregon.
However, one wonders what the pregnant mom might switch to the newborn, after feeding him together with her physique for 9 months. The author Lucía Etxebarria opened the talk yesterday with a considerably loopy concept on her social networks. “At first look evidently Ana Obregón’s granddaughter seems like her pregnant mom,” mentioned the all the time controversial writer of Beatriz and the Heavenly Bodies, alluding to an alleged resemblance of Ana Sandra to the lady who gave beginning to her on the Memorial Regional Hospital of Florida, whose id and picture have been revealed final week by {a magazine}: “We will know higher once we see the christening unique – which has already been bought to HELLO! – and we see that child slightly older “continues Etxebarria. At the second, it’s the presenter who has shared pictures of her child on her social networks:
The author aired the query about what a pregnant mom’s child might have, alluding to epigenetics, and giving examples comparable to “the story of a girl who had undergone in vitro insemination with one other individual’s ovum, with the concept this might stop the transmission of a genetic illness. But her child was born with the genetic illness of the pregnant mom and never of the one who donated the egg”. She additionally spoke of different related circumstances comparable to the looks of “infants born with a spot on the pores and skin that the pregnant mom had. And infants who’re born with black eyes despite the fact that the daddy has blue eyes and the egg donor additionally has blue eyes. But the pregnant lady had black eyes.”
After speaking about Darwin’s concept of evolution and Lamarck’s paradigm, his publish generated all types of feedback, most of them destructive, criticizing his concept and describing what he was exposing as “barbarities with out scientific foundation”. “As a biologist, and out of respect for you, I’d ask you, Lucía, to not be ridiculous anymore.” Others puzzled if there wasn’t one thing true in her concept: “The pregnant mom isn’t an oven that makes pizzas. She transmits to the newborn all types of ‘content material’ which can be in her. Is it so laborious to know?”.
What does science say about it?
Epigenetics in being pregnant is a subject that we addressed at NIUS a yr in the past, following a examine by the INCLIVA Health Research Institute that confirmed how the pregnant mom transmits adhesion proteins to the embryo. “The mom provides vitality to the embryo to implant itself,” mentioned the consultants in epigenetics who examine the potential modifications in DNA that may be generated by environmental elements, to know the ailments that trigger these modifications and attempt to remedy them.
Epigenetics helps within the implantation of the embryo: “It is as if the mom gave her a chorizo sandwich in order that she has vitality”niusdiario.es
The INCLIVA workforce, led by Dr. Felipe Villella, verified that moms have been moms since earlier than what was identified, or no less than that their uterus acts in a “maternal” method, encouraging the embryo to implant and start the gestation, and modulating genetic data to favor implantation.
The researchers noticed how the mom modifies the embryo in order that it produces “particular adhesion proteins” in order that it will possibly implant itself within the endometrium at the start of the being pregnant.
It was an essential discovery inside epigenetics, the science that analyzes the affect of environmental elements on our genes. Seeing how the mom can one way or the other modulate the DNA of her son is an fascinating discipline to research.
The pregnant mom transmits vitality to start out the method
“We are seeing that the mom is able to transmitting mitochondrial DNA to the longer term youngster as a method of passing vitality to it. She passes data from the mitochondria in order that it will possibly generate vitality and thus be capable to begin the implantation course of, and begin the being pregnant.”
“It is as if the mom gave the embryo a chorizo sandwich in order that it has energy when implanting,” Villella defined to us a few course of that he described as “fascinating.”

According to this researcher, the mom has an equally essential function because the genes in what the newborn might be like. “The mom is all the time genetically modifying the embryo. Regardless of the place the genes come from and what sort of genes they’re, from the mom herself or from a donor. The oocyte is in an surroundings and there may be already data and a potential genetic transformation, ”she defined.
The mom doesn’t change the DNA however she will modulate it
The mom “can not change a gene”, however “she will particularly modulate the genetics that exist already”. That is, “the mom can present data to the present genes of her future youngster to transmit her data to him.”
The mom epigenetically modifies the embryo
We requested the knowledgeable why it has been the case that some infants with egg donors resemble the moms who gave them beginning. The reply is because of a number of elements. “The very first thing is that in replica clinics they search for related donors, who’ve the identical traits (brown eyes, black eyes, and so on.), acquired habits (character, tics) additionally play a job, however there may be one other scenario that we’ve been learning for a while, and that’s that the mom epigenetically modifies the embryo.
Always primarily based on epigenetics, the researchers consider that “particular areas of the DNA may be modified in order that sure particular genes are expressed which have, or could also be associated to, bodily elements of the pregnant lady. Let’s not neglect that epigenetics is a change in a single’s personal system”.
Definitely. How a lot of the mom (no matter whether or not the oocyte is hers or not) influences the kid? “For higher or worse, we expect loads. There are sure ailments comparable to weight problems that the mom can transmit to the newborn’s DNA and predispose him to endure from it”, they clarify from INCLIVA, whose analysis is directed on this sense, to forestall potential ailments.
The mom’s life-style also can affect the newborn she is carrying. “Diet, tobacco use, weight problems, alcohol consumption or air pollution… it’s identified that these elements find yourself producing small modifications within the DNA in the long term, and that finally ends up inflicting sure ailments.” The different method is to switch these ailments (for now within the laboratory).

The knowledgeable clarifies that this doesn’t imply that DNA may be modified. And he provides Don Quixote for example. “The textual content can be the genetic code, however he will get a espresso stain and it turns into a blur. You could not learn that web page nicely, despite the fact that the textual content continues to be there. The reader must skip that paragraph. The genetic code is what you’ve, however sure modifications can happen that don’t enable that genetic data to be learn or transcribed. Since that data can’t be learn, if that gene has to supply a particular protein for one thing to occur, because it can not learn it, it can not produce it and that may find yourself producing a potential illness.”
Therefore, what’s at the moment being studied is how epigenetics can be the “blur” that would have an effect on the newborn’s genetic code. “What science is doing is with the ability to establish and perceive these ‘ink spots’, both throughout being pregnant or all through life, and to know particularly the place these modifications happen in an effort to attempt to remedy them.”
