The study shows that when an egg is fertilized, stem cells leave the bone marrow and travel via the bloodstream to the uterus, where they help transform the uterine lining for implantation. If the lining fails to go through this essential transformation, the embryo cannot implant, and the body terminates the pregnancy.

But knowing that bone marrow has a significant role is a paradigm shift. In this study, the researchers were able to prove the physiological relevance of stem cells to pregnancy. In two mouse models with the Hoxa11 gene defect, which presents in mice as a defective endometrium, the researchers found that a bone marrow transplant from a healthy donor could improve fertility by promoting sufficient decidualization of the endometrium. In mice with only one copy of the defective gene, the transplant saved pregnancies that would otherwise have been lost and increased litter sizes, while in the mice with two bad copies of the gene, which were thus entirely infertile, the transplant caused growth and repair of the defective endometria.

This study was possible due to a methods breakthrough that Tal and Taylor made a few years ago. Before a bone marrow transplant , chemotherapy or radiation clears the body of the existing bone marrow, so that the donor bone marrow can take its place.

Though more research is needed prior to clinical trials, Tal and Taylor see hope for the patients they treat for infertility on the clinical side of their practice in this latest advance. Bone marrow can be considered another critical reproductive organ. This finding opens up a new potential avenue for treatment of a condition that has been untreatable in the past. Leet and Clara Guthrie Patterson Fellowship funded the research.

The breakthrough paves the way for lesbian couples to have children that are biologically their own. Researchers at Newcastle upon Tyne University say their technique will help lead to new treatments for infertility. But critics warn that it sidelines men and raises the prospect of babies being born through entirely artificial means.

But recently a team of scientists announced they had made artificial sperm from human bone marrow , and media reports abounded with the dire news that my goodfellas and by extension, me had been rendered unnecessary. There are at least half a dozen reasons why such speculation is silly, some scientific and some practical. For example, as long as sex feels good and remains no more expensive than dinner and a bottle of wine, most people will use natural-grown sperm. Still, suggests Gregory Stock, director of the program on medicine, society and technology at the UCLA School of Medicine and the CEO of a biotech company called Signum Biosciences, it is very interesting that there were any stories at all.

Bone stem cells turned into primitive sperm cells

My daughter had a bone marrow transplant when she was The donor was male. She is now 30 and is pregnant. She just had some blood work done, and the lab called to say that the blood sample they sent in was male, not female! Does she need to worry about this? Rest assured the baby will not look like the donor! This is due to the fact that the baby will inherit DNA from Mom, not the donor. To begin, the cells in your body that create blood cells bone marrow are destroyed by chemotherapy or radiation. Bone marrow cells are harvested from the donor and injected into you.

Will science render men unnecessary?

Human bone marrow has been used to create early-stage sperm cells for the first time, a scientific step forward that will help researchers understand more about how sperm cells are created. For the experiment, Prof Nayernia and his team took bone marrow from male volunteers and isolated the mesenchymal stem cells. These cells have previously been found to grow into other body tissues such as muscle. They cultured these cells in the laboratory and coaxed them into becoming male reproductive cells, which are scientifically known as 'germ cells'. Genetic markers showed the presence of partly-developed sperm cells called spermatagonial stem cells, which are an early phase of the male germ cell development.

Bone marrow failure diseases frequently occur in women who are young and of child bearing age. People with these diseases have legitimate concerns about whether a pregnancy will cause their infants to suffer from the disease or its treatment, or whether their own disease will relapse.

Researchers found that when an egg is fertilised, stem cells leave the bone marrow and travel via the bloodstream to the uterus, where they help transform the uterine lining for implantation.

Cells that make bone marrow also travel to the womb to help pregnancy

I guess after being told to "Go Fuck Yourself" for so many years, these scientists finally found a way to do it. There will be some interesting debates raging about this one for a long time. I'm of the opinion that on the whole, we are better off with the process of gene mixing than practicing self-eugenics. Since when is human reproduction about strengthening the gene pool, and since when are your "gay friends" inherently unable to reproduce naturally? Better question is "since when is natural a good thing"?

How bone marrow boosts chances of a healthy pregnancy

It may be hard to get and stay pregnant for some would-be mums, but there is hope. Scientists have discovered the vital role bone marrow plays in pregnancy, which can lead to new therapies in the future. In 10 seconds? Stem cells play a key role in successful pregnancies. Read the science. What exactly was discovered?

Female sperm can refer to either: A sperm which contains an X chromosome, produced in the Thus, a woman's cells will remain in the man's testicles long enough to be from the bone marrow of male volunteers, entirely in-vitro (outside the human body) Male egg · Male pregnancy · Same-sex marriage and procreation.

Log in Advanced Search. A study in mice suggests that bone marrow-derived stem cells may play a role in establishing pregnancy. The research showed that the stem cells can travel through blood circulation to the uterus, making it more receptive for a new embryo. Specifically, the authors showed that these cells concentrate in the lining of the uterus where the embryo is about to implant. There, they become specialised uterine cells or decidual cells, which are critical for maintaining the embryo.

Since the late s, scientists have explored how to produce sperm where all of the chromosomes come from a female donor. Creating female sperm was first raised as a possibility in a patent filed in [3] by injecting a woman's cells into a man's testicles, though the patent focused mostly on injecting altered male cells into a man's testes to correct genetic diseases. In , Japanese scientists partially confirmed such techniques by creating chicken female sperm in a similar manner.

Bone marrow-derived cells play a role in changes to the mouse uterus before and during pregnancy, enabling implantation of the embryo and reducing pregnancy loss, according to research published September 12 in the open-access journal PLOS Biology. Although the study was done in mice, it raises the possibility that dysfunction of bone marrow-derived progenitor cells may contribute to implantation failure and pregnancy loss in women. Bone marrow progenitors can become either blood or tissue cells. Within the uterus they differentiate into endometrial tissue cells in the lining of the womb, but until now it was not known if they have a function in pregnancy.
