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.

Stem cells taken from men's bone marrow can be coaxed into something that resembles an immature sperm cell, researchers working in Germany say. They hope to use their findings to come up with new and better fertility treatments for men and women.

Nayernia, now at the UK's Newcastle University and the North East England Stem Cell Institute , had previously grown sperm cells from mouse bone marrow and used them to fertilise mouse eggs and create living baby mice. In the latest research, his team worked with men who were about to have bone marrow transplants, a common treatment for cancer.

The researchers removed some of the bone marrow, a rich source of so-called adult stem cells, cells the body uses to replenish blood, bone, muscle and other tissues. Writing in the journal Reproduction: Gamete Biology , Nayernia and colleagues say they searched for stem cells that most closely resembled germ cells, the cells found in the testes of men and ovaries of women that eventually give rise to sperm and eggs.

Stem cell science counts on being able to redirect a cell so it will create a particular tissue. The more immature a stem cell is, the more malleable it is, which is why many researchers want to work with and study stem cells taken from days-old embryos. Unlike mature tissue, stem cells live longer, with some types being virtually immortal under the right lab conditions.

If scientists can take bone marrow cells from an infertile man and turn them into sperm, he could father a child using standard techniques such as in vitro fertilization IVF. Other researchers have done similar work in female mice, taking bone marrow cells and turning them into egg cells. Tags: sexual-health , biology , biotechnology.

Pregnancy in Bone Marrow Failure Disease

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. This study was made possible by a methods breakthrough that Dr Tal and Prof Taylor made a few years ago.

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.

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.

Bone marrow stem cells may be vital for pregnancy

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. Experiments have created eggs and sperm, so-called artificial gametes, from embryonic stem cells and other cell types for years now with limited success, so the bone marrow work does not represent a giant leap. And the stories are reminiscent of some that were printed 10 years ago when the birth of Dolly the sheep, the first mammal cloned from an adult cell, was announced. We men were declared washed up then, too.

Female sperm

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.

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.

Sperm Cells Created From Human Bone Marrow

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.

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. In usual circumstances, when foreign cells such as cells or organs from other people, or infectious bacteria are put into a human body, its immune system will reject such cells or organs.

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. Previous studies had shown that small numbers of bone-marrow stem cells contribute to the renewal of the lining of the non-pregnant uterus, but it remained unknown whether they play a part in pregnancy.

Bone stem cells turned into primitive sperm cells

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.

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

By Roxanne Khamsi. In a first step towards creating artificial sperm cells, researchers have turned human bone marrow tissue into primitive sperm cells. If these precursor cells can be coaxed into becoming fully functioning sperm cells, the technique could allow infertile men to father their own children, and even allow women to produce their own sperm. But experts caution that provoking the sperm precursors to fully mature presents a serious challenge.

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. Experience from published reports suggests that in the past ten years, both maternal health and fetal outcomes have improved in women with aplastic anemia and PNH.
