Reproductive scientists create mice from 2 fathers

Dec 08, 2010
US scientists have used stem cell technology to create mice from two fathers, an advance that they say could help preserve endangered species and even help same-sex couples have their own genetic children one day.

Using stem cell technology, reproductive scientists in Texas, led by Dr. Richard R. Berhringer at the M.D. Anderson Cancer Center, have produced male and female mice from two fathers.

The study was posted today (Wednesday, December 8) at the online site of the journal .

The achievement of two-father offspring in a species of mammal could be a step toward preserving endangered species, improving livestock breeds, and advancing human (ART). It also opens the provocative possibility of same-sex couples having their own genetic children, the researchers note.

In the work reported today, the Behringer team manipulated fibroblasts from a male (XY) mouse fetus to produce an induced pluripotent stem (iPS) cell line. About one percent of iPS cell colonies grown from this XY cell line spontaneously lost the , resulting in XO cells. The XO iPS cells were injected into blastocysts from donor female mice. The treated blastocysts were transplanted into surrogate mothers, which gave birth to female XO/XX chimeras having one from the original male mouse fibroblast.

The female chimeras, carrying oocytes derived from the XO cells, were mated with normal male mice. Some of the offspring were male and female mice that had genetic contributions from two fathers.

According to the authors, "Our study exploits iPS cell technologies to combine the alleles from two males to generate male and female progeny, i.e. a new form of mammalian reproduction."

The technique described in this study could be applied to agriculturally important animal species to combine desirable genetic traits from two males without having to outcross to females with diverse traits.

"It is also possible that one male could produce both oocytes and sperm for self-fertilization to generate male and female progeny," the scientists point out. Such a technique could be valuable for preserving species when no females remain.

In the future, it may also be possible to generate human oocytes from male iPS cells in vitro. Used in conjunction with in vitro fertilization, this would eliminate the need for female XO/XX chimeras, although a surrogate mother would still be needed to carry the two-father pregnancy to term.

Using a variation of the iPS technique, the researchers say "it may also be possible to generate sperm from a female donor and produce viable male and female progeny with two mothers."

The authors also caution that the "generation of human iPS cells still requires significant refinements prior to their use for therapeutic purposes."

I think the authors of the original article and of this article are overstating the findings of the study a little bit. Yes technically the genetic material could be attributed to 2 fathers, but a chimeric female was involved. The genetic material passed through her germline, which and would have been reprogrammed. So this may not be any different technically than passing on the X she got from Dad anyway, except for the iPS technology.

Fair point. I thought about this too. I believe they would take the Y chromosome from a separate human male. The mothers' DNA would be mixed resulting in what is clearly their child, but they would require a male sex (Y) chromosome. The Y chromosome sees relatively little variation anyway due to lack of crossing, so they'd basically just be selecting which population from which to take a Y chromosome (the specific father would be less important, and the population from which it comes probably isn't very important either.. though that might make an interesting study). The other, more relevant, 45 chromosomes would be theirs (genetics experts feel free to nitpick/correct).

it is not like that, this chimera dont mix the dna from the X0 and the XX organism, it is mosaic organism, it will produce oocytes from both organism and you take only these you want, the new thing here is they are able to get rid of the Y chromosome, it would be interesting if they can copy the X(from the male) and from X0 you can have XX and then to create female from male.

The problem you don't mention is the meaning of "perfect" and "quality of life". Because the personal definitions of these terms might differ between the "parents" and their offspring. In extreme cases parents might be killed by their offspring for having them condemned to a life they abhor.

I guess that makes some sense. Although when this becomes possible (swapping out chromosomes), then designer chromosomes will also be right around the corner. I'm not sure how I feel about that one.

So what is natural law? Making children that you cannot take care of is wrong. It harms both the children and the society that has to take care of them. Therefore it should be punished and prevented.

Some ideas: sterilization (reversible) should be used for repeated offenders only. Some combination of fines, increased taxes, public work, low amounts of jail-time or consultations with a psychologist would be enough to enforce this law. Its just this mindset of some people that they can pop out a baby whenever they want that needs to change, so even actually making it against the law, but without much enforcement could help, IMHO.

Genetic technologies certainly raise many new issues, especially concerning the ways a parent can'improve' their childs genome. Removing disease or disability? great! Giving them extraordinary traits to give advantage to them? Sounds good to me but other people will object. Changing their physical appearance from human norm?

Children of people recieving welfare have lower earnings and are more often unemployed themselves when they grow up (this problem is maybe more acute here in Slovakia, we have sometimes third generation of people that never worked). Also, if welfare recipient has less children, he/she can take care of them better than if he/she has more.

Hmm...well if the two consenting adults are male, as enabled by the technology discussed in the top article, then:
1) They have money, as the technique used would be an expensive way to have a child.
2) PROBABLY they would have disscussed the matter in depth - this would NOT be an accident!

So this new technology would appear to be beneficial in the fact it would create a family from people that CAN take care of their kids well.

In the matter of poor people having kids - I think our money would be better spent figureing out how to feed and educate them rather than enforcing some kind of anti-breeding laws against them. They are NOT some kind of sub-human. Simply disadvantaged or disenfranchised by our social system.

Re: Quantum_Conundrum
The fashionable ideology that "artificial" lacks the inherent goodness of "natural" is an appealing, but hopelessly simplistic notion of the intellectually chic. Artifice is the result of a deliberate intent to make. Nature also "makes" things, using a set of basic building blocks common throughout the universe. Exchanging infinite time for deliberate design, nature has ingeniously built plants, planets, galaxies and unimaginable constructs which seem to structure the universe itself. What we call "natural" is simply the result of whatever set of rules nature has followed in fashioning our observable reality. [...] Discoveries in the "nano" technologies of bio, molecular, and micro engineering will re-edit the nomenclature of "natural" versus "unnatural", blurring if not erasing the line of distinction between[...]"God-given" and "man-made".

Personally, I am a fan of Eugenics. If we were a truly intelligent species we would breed ourselves like we do our livestock and pets. We would control our population and enforce both physical and mental standards (and no I am not talking about killing people, just controlling reproductive rights).

If we had started doing this 1000 years ago our lifespans could probably have been greatly increased by now too, not to mention eliminating inherited disease. I for one would rather be an extremely handsome, more intelligent, long lived individual, and if all women were beautiful with great legs and brains I certainly wouldn't complain.

Lots of genetics defects are identified in the genome, if screening is obligatory, and when a problem is detected you choose the right embrio and thats it, the next step is to identify all the genetic diseases, where is the mistace in the code, this will solve hypertonia, gout(podagra), diabitis(type 1 and 2) etc. this will solve this problems only for several generations, what elce you want to solve-to create resistancy to HIV?It will be much more easy to find pill(we are really close even now) for that than to gm humans to be resistant.

Wait till they cross the species barrier, then you can ask: So now how do we argue against human-sheep marriage?


You really have to ask this? It is obvious that inability of sheep to give consent is the reason why human-sheep marriage is illegal.

Personally, I am a fan of Eugenics. If we were a truly intelligent species we would breed ourselves like we do our livestock and pets. We would control our population and enforce both physical and mental standards (and no I am not talking about killing people, just controlling reproductive rights).

If we had started doing this 1000 years ago our lifespans could probably have been greatly increased by now too, not to mention eliminating inherited disease. I for one would rather be an extremely handsome, more intelligent, long lived individual, and if all women were beautiful with great legs and brains I certainly wouldn't complain. (actually I already have all but one of the benefits) (So if you rate this post a one we'll know it's because you're ugly, stupid and insanity runs in your family)


Somebody here is ugly, stupid and insane, they rated my post a 1.

David Brin (a science fiction author) writes of the responsibility of advanced species to 'uplift' other species into sapient beings. If we gave intelligence to sheep, then marriage could indeed become a debatable issue.

In that case, it would not be a debatable issue, but a non-issue, such a marriage would be allowed.

Concisely.

I'm not an expert on sheep but I'm fairly sure there would be an actual reason for prevention of this practice, like being a wholly different species.

For what reason other than prejudice would this be prevented? We are talking about sapient beings here. Fully capable of expressing consent, and feeling love for a different person. Is this not the same as trying to prevent same sex marraige as being unnatural and disgusting? Please note that I am not talking about bestiality here, just making a case for two adult, rational beings being allowd to express their love and commitment for one another.

And what about the concept of uplift itself? Is it wrong to give intelligence to other species?

There is no such reason, except prejudice. Among two rational beings, marriage should and would be allowed, irregardless of sex or species.

-Don't know how this was done but it apparently involved some kind of manipulation and a surrogate.

-And I have to agree with shotman above. It is obvious that some people should NOT be allowed to have children. It is the only way to prevent atrocities such as this:

-what we do in a civilized society is identify problems such as this, and then go about finding decent and equitable solutions for them. This solution will most likely not occur during our lifetimes, but eventually the science will exist and a generation with the proper mindset will see it implemented.

Only a few gens ago it was unthinkable that women would share the same freedoms as men, or that pornography would be legal. We cannot predict how people will deal with this problem, but we can look forward to a day when it will be solved. It HAS to be solved for the species to mature.

I think that eventually reproduction will be outsourced and humans will prefer to be born without the organs and hormones which cause so much wasted time and energy and damage to our bodies. In the interim there will be a period where people will be born in a sterile state, which can only be reversed after the successful completion of an intense period of education and examination.

Child-bearing and rearing is perhaps the single most important profession one can practice and yet it is the only one which requires absolutely no qualification for. All of society suffers from this. When we can begin to reduce the number of people damaged before and after birth by incompetent parents we will see crime and illness and suffering plummet.
