Woman get pregnant with 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. 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.

Stem Cells and Same Sex Reproduction

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. Reshef Tal , first author of the study and assistant professor of obstetrics, gynecology and reproductive sciences at Yale. 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 made possible by a methods breakthrough that Tal and Taylor made a few years ago.

Before a bone marrow transplant, chemotherapy or radiation is used to clear 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.

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.

Female sperm

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. Well, what does that say about marriage laws? About whether men are needed?

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.

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.

Как и то, что шахта лифта защищена усиленным бетоном. Сквозь клубящийся дым Сьюзан кое-как добралась до дверцы лифта, но тут же увидела, что индикатор вызова не горит. Она принялась нажимать кнопки безжизненной панели, затем, опустившись на колени, в отчаянии заколотила в дверь и тут же замерла.

Сьюзан с трудом воспринимала происходящее. - Что же тогда случилось? - спросил Фонтейн.  - Я думал, это вирус. Джабба глубоко вздохнул и понизил голос. - Вирусы, - сказал он, вытирая рукой пот со лба, - имеют привычку размножаться. Клонировать самих .

Для него все шифры выглядят одинаково, независимо от алгоритма, на основе которого созданы. - Не понимаю, - сказала.  - Мы же говорим не о реверсии какой-либо сложной функции, а о грубой силе. PGP, Lucifer, DSA - не важно. Алгоритм создает шифр, который кажется абсолютно стойким, а ТРАНСТЕКСТ перебирает все варианты, пока не находит ключ. Стратмор ответил ей тоном учителя, терпеливого и умеющего держать себя в руках: - Да, Сьюзан, ТРАНСТЕКСТ всегда найдет шифр, каким бы длинным он ни.  - Он выдержал длинную паузу.

Sep 12, - A woman's bone marrow may determine her ability to start and to get pregnant, allowing us to track the transplanted bone marrow cells and.

Вобрав голову в плечи, он ударил убийцу всем телом, отшвырнув его на раковину. Со звоном разбилось и покрылось трещинами зеркало. Пистолет упал на пол.

 Двадцать миллионов? - повторил он с притворным ужасом.  - Это уму непостижимо. - Я видел алгоритм. Уверяю вас, он стоит этих денег.

Will science render men unnecessary?

Беккеру удалось оторваться от убийцы, и он рванулся к двери. Халохот шарил по полу, нащупывая пистолет. Наконец он нашел его и снова выстрелил. Пуля ударила в закрывающуюся дверь.

Старик застонал. - Он называл ее… - Речь его стала невнятной и едва слышной.

Если будет ошибка, мы попробуем снова, пока не добьемся успеха. - Плохой совет, мистер Беккер, - огрызнулся Джабба.  - Нужно сразу быть точным. У шифров-убийц обычно есть функция злопамятства - чтобы не допустить использования метода проб и ошибок.

Пуля задела Беккера в бок, когда он уже почти обогнул угол здания. Он почувствовал это лишь после того, как сделал пять или шесть шагов. Сначала это напомнило сокращение мышцы чуть повыше бедра, затем появилось ощущение чего-то влажного и липкого. Увидев кровь, Беккер понял, что ранен. Боли он не чувствовал и продолжал мчаться вперед по лабиринтам улочек Санта-Круса. Халохот настойчиво преследовал свою жертву.

Сьюзан представила себе Хейла в западне, в окутанной паром ловушке. Может быть, он что-нибудь поджег. Она посмотрела на вентиляционный люк и принюхалась. Но запах шел не оттуда, его источник находился где-то поблизости.
