Can a woman get pregnant from bone marrow

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.

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.

Woman’s bone marrow may determine her fertility

Please create an account to participate in the Slashdot moderation system. 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?

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. According to New Scientist magazine, the scientists want to take stem cells from a woman donor's bone marrow and transform them into sperm through the use of special chemicals and vitamins.

How bone marrow boosts chances of a healthy pregnancy

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. Though more research is needed prior to clinical trials, the research team see hope for the patients they treat for infertility on the clinical side of their practice.

Will science render men unnecessary?

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.

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.

But knowing that bone marrow has a significant role is a paradigm shift.

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. In July , biologist Karim Nayernia at the University of Newcastle-upon-Tyne in the UK, and colleagues reported they had successfully converted stem cells from mouse embryos into functioning sperm that could fertilise mouse eggs and produce live offspring. The researchers mixed these cells with proteins that promote cell growth and vitamin A, which appears to play an important role in sperm development.

Bone stem cells turned into primitive sperm cells

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 Stem Cells May be Vital for Pregnancy

 Мы это уже обсудили. Забыла. - Там проблема с электричеством.

Мне нужен консьерж.

 Чед? - В дверях его кабинета возникла Мидж Милкен, эксперт внутренней безопасности Фонтейна. В свои шестьдесят она была немного тяжеловатой, но все еще весьма привлекательной женщиной, чем не переставала изумлять Бринкерхоффа. Кокетка до мозга костей, трижды разведенная, Мидж двигалась по шестикомнатным директорским апартаментам с вызывающей самоуверенностью. Она отличалась острым умом, хорошей интуицией, частенько засиживалась допоздна и, как говорили, знала о внутренних делах АНБ куда больше самого Господа Бога.

Она отправляла его на фиктивный адрес этого клиента, и переадресующая компания, выполняя свои договорные обязательства, пересылала этот маяк на подлинный адрес. Попав по назначению, программа фиксировала свое местонахождение в Интернете и передавала его в АНБ, после чего бесследно уничтожала маяк. Начиная с того дня, анонимные переадресующие компании перестали быть для АНБ источником серьезных неприятностей. - Вы сможете его найти? - спросил Стратмор. - Конечно. Почему вы не позвонили мне раньше. - Честно говоря, - нахмурился Стратмор, - я вообще не собирался этого делать.

Он бросил быстрый взгляд на Сьюзан, которая по-прежнему сидела на стуле, обхватив голову руками и целиком уйдя в. Фонтейн не мог понять, в чем дело, но, какими бы ни были причины ее состояния, выяснять это сейчас не было времени. - Нужно решать, сэр! - требовал Джабба.  - Немедленно.
