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.

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? Stem cells arriving from the bone marrow to the uterus transform its lining and help the implantation of the embryo by becoming decidual cells essential for getting and staying pregnant.

If this transformation does not occur, the pregnancy will terminate. Read the paper. What mechanism is at play here? It turns out they also help transform the endometrium, the inner lining of the uterus. A damaged endometrium can result in repeated lost pregnancies or infertility and the findings raise the hope of science being able to fix this condition. More on factors affecting embryonic implantation. So, how did they discover this?

Earlier attempts also destroyed the mice's eggs, but the researchers have managed to refine their technique to keep them intact this time.

The next step was to make two groups of mice pregnant, one before and one after a healthy bone marrow transplant to test if bone marrow played a role in pregnancy. Find out more. Which they proved, right? Anything else they discovered? For this study, they investigated the role of the protein Hoxa11, present in both the bone marrow and the uterus. When Hoxa11 is partially absent, lab mice cannot maintain their pregnancies and when it is completely lacking, pregnancy doesn't even start.

But when partially or completely Hoxadeprived mice receive bone marrow transplants from healthy peers, both groups gain the ability to become pregnant. Read more. What can we expect in the future? The study was done in mice and Hoxa11 is worthy of further investigation before human trials can begin. The findings - that a bone marrow transplant from a healthy donor could improve fertility - are great news.

Up to now, there was no effective treatment for the majority of women with recurrent implantation failure and loss of pregnancies due to endometrial defects, therefore the discovery offers hope for new therapies and the possibility of having babies in the future.

Four years later a Japanese team repeated the feat and managed to generate sperm that produced healthy and fertile mice. Researchers described the studies as the first steps to produce sperm for infertile men or potentially allow same-sex female couples to produce artificial sperm and have their own biological daughters.

Will science render men unnecessary?

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.

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.

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.

Pregnancy in Bone Marrow Failure Disease

Same-sex female partners who want to have a baby have a number of different treatment options to help them conceive. Reciprocal IVF is increasingly popular with lesbian couples because both partners play an important role in conceiving the child. Some women feel it strengthens their bonds both with the child and with each other. In reciprocal IVF, one partner supplies the eggs to be used for IVF, while the other partner is the gestational carrier of the pregnancy. The menstrual cycles of both partners are synchronized so they are ready for treatment at the same time. The partner donating the eggs goes through ovarian stimulation to produce multiple eggs. The eggs are then extracted from her ovaries and fertilized with donor sperm in the laboratory. The partner who will carry the pregnancy is prepared for embryo transfer.

Bone Marrow Stem Cells May be Vital for Pregnancy

Stem cells have generated such an enormous amount of interest, in part, because of their applications related to areas such as fertility and genetics. In that same light, their interest for solving reproductive challenges has also generated a great deal of controversy. This is particularly true in the application of stem cells to facilitate reproduction for gay couples. At present, there are a number of research laboratories that are focused on the creation of cells that are genetically male but have been produced from eggs. Alternately, they are also trying to create sperm from female eggs.

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. But the goal of modern therapy and modern obstetrics is to minimize both maternal and fetal complications.

Bone marrow stem cells may be vital for pregnancy

My daughter had a bone marrow transplant when she was The donor was male. She is now 30 and is pregnant.

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.

The experiment marks the first time that any nonreproductive human tissue has been transformed into gametes. If the cells can be grown into mature sperm, the technique would allow men without functioning sperm, or even testes, to father children.

Oct 15, - According to new research, a woman's bone marrow may determine her ability “You must have ovaries to make eggs, and you must also have a uterus to but it's remained unknown if and how stem cells affect a pregnant uterus. Other members found these Giving Funds, Charitable Organizations and.

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. If the lining fails to go through this essential transformation, the embryo cannot implant, and the body terminates the pregnancy. Study first author Dr. Using mice, researchers found that a bone marrow transplant from a healthy donor could improve fertility.

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. The research centres around stem cells - the body's 'mother' cells which can turn into any other type of cell.

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. It is therefore concluded that most of the W-bearing PGC could not differentiate into spermatozoa because of restricted spermatogenesis. One potential roadblock to injecting a woman's cells into a man's testicles is that the man's immune system might attack and destroy the woman's cells.

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. In most men, spermatagonial cells eventually develop into mature, functional sperm but this progression was not achieved in this experiment. Earlier research led by Prof Nayernia using mice, published in Laboratory Investigations, also created spermatagonial cells from mouse bone marrow.
