The incredible promise of stem cell research to at minimum advance scientific understanding and perhaps ultimately to treat persons with devastating diseases gives moral force to efforts to conduct this research.

However, stem cell research has been riddled with ethical questions, in part because the predominant methods being used to derive or attempt to derive human embryonic stem cells require destruction of the embryo. Nevertheless, the ethical debates surrounding human embryonic stem cell research have not been solely related to those associated with the embryo.

For instance, the creation of chimeras in some stem cell research has elicited concerns. Oocyte harvesting, which is essential to the creation of human embryonic stem cells raises concerns related to safety of the donor. Other important ethical issues relate to informed consent of both donors of gametes and embryos as well as recipients of stem cells and stem cell products. Further, there has been some concern related to the commercialization of the process, justice, and the responsible conduct of research.

In addressing the ethical issues associated with human embryonic stem cell research, it is important to note that they are being deliberated in a setting where scientific excitement is high, there are extraordinarily powerful arguments for access to investigational treatments, and the financial, moral and political stakes are great. In an attempt to minimize the ethical issues associated with human embryonic stem cell research so important research can proceed, professional groups have issued guidelines for the ethical conduct of this research and its oversight.

Systematic data regarding these efforts should be collected in order to enhance the likelihood that they meet their ethical goals.

Translational Stem Cell Research

Most cells in the body are differentiated cells. These cells can only serve a specific purpose in a particular organ. For example, red blood cells are specifically designed to carry oxygen through the blood. All humans start out as only one cell. This cell is called a zygote, or a fertilized egg. The zygote divides into two cells, then four cells, and so on. Eventually, the cells begin to differentiate, taking on a certain function in a part of the body.

Ethical Implications in the Use of Embryonic and Adult Neural Stem Cells

Author information

Manuel J. The new discoveries, the extraordinary dynamism in human stem cell SC research, and the great expectations of the benefits in clinical treatment of many diseases are on the edge of unparalleled advances in both: 1 the understanding of basic mechanisms of cell differentiation and development and 2 the translation from basic research to new clinical therapies. Human stem cells are obtained from different sources, such as embryo, fetal, and adult tissues, in vitro induction iPS cells or transdifferentiation. The evidence that these cells are pluripotent or multipotent , meaning they have the ability to differentiate into all body tissues or tissues of the same lineage, raises the possibility that they could regenerate diseased or damaged tissue in diseases that until now have had no effective treatments. Human stem cell research and therapy raise important bioethical considerations because of the human nature of these cells and their peculiar characteristics. Here we discuss the bioethical aspects of basic human SC research and the conditions necessary for the translation of basic preclinical research into clinical use of SC.

Metrics details. Rapid progress in biotechnology has introduced a host of pressing ethical and policy issues pertaining to stem cell research. In this review, we provide an overview of the most significant issues with which the stem cell research community should be familiar. We draw on a sample of the bioethics and scientific literatures to address issues that are specific to stem cell research and therapy, as well as issues that are important for stem cell research and therapy but also for translational research in related fields, and issues that apply to all clinical research and therapy. Although debate about the moral status of the embryo in human embryonic stem cell research continues to have relevance, the discovery of other highly multipotent stem cell types and alternative methods of isolating and creating highly multipotent stem cells has raised new questions and concerns. Induced pluripotent stem cells hold great promise, but care is needed to ensure their safety in translational clinical trials, despite the temptation to move quickly from bench to bedside.

Он почувствовал болезненное жжение в боку. Мое тело мне больше не принадлежит. И все же он слышал чей-то голос, зовущий .

Сьюзан словно отключилась от Хейла и всего окружающего ее хаоса. Энсей Танкадо - это Северная Дакота… Сьюзан попыталась расставить все фрагменты имеющейся у нее информации по своим местам. Если Танкадо - Северная Дакота, выходит, он посылал электронную почту самому себе… а это значит, что никакой Северной Дакоты не существует. Партнер Танкадо - призрак. Северная Дакота - призрак, сказала она .

Профессионализм Хейла достиг высокого уровня, и у него появились знакомые среди интернет-пользователей по всему миру. Он был представителем новой породы киберпсихов и общался с такими же ненормальными в других странах, посещая непристойные сайты и просиживая в европейских чатах. Его дважды увольняли за использование счета фирмы для рассылки порнографических снимков своим дружкам.

Для него все шифры выглядят одинаково, независимо от алгоритма, на основе которого созданы.

Вы полагаете, что Северная Дакота может быть где-то. - Возможно.  - Стратмор пожал плечами.

Отчаянно вырываясь из его рук, Сьюзан локтем с силой ударила Хейла. Он отпустил ее и прижал ладони к лицу. Из носа у него пошла кровь.

Цифровая крепость исчезнет бесследно. Словно ее никогда не. Мы похороним ключ Хейла и станем молиться Богу, чтобы Дэвид нашел копию, которая была у Танкадо. Дэвид, вспомнила Сьюзан. Она заставляла себя не думать о .

Кровь, вытекающая из головы, в голубоватом свечении казалась черной. На полу возле тела Хейла лежал листок бумаги. Сьюзан наклонилась и подняла .

Линейная мутация. И все-таки он пошел в обход. Интересно, о чем он. У Бринкерхоффа подогнулись колени. Он не мог понять, почему Мидж всегда права.

Беккер позвонил одному из своих коллег: - Тебе что-нибудь известно об Агентстве национальной безопасности. Это был не первый его звонок, но ответ оставался неизменным: - Ты имеешь в виду Совет национальной безопасности. Беккер еще раз просмотрел сообщение. - Нет. Они сказали - агентство.

Терпкий аромат красного вина ударил в ноздри Беккера, когда падре Херрера опустил перед ним серебряную, отполированную миллионами рук чашу. Немного рано для алкогольных напитков, подумал Беккер, наклоняясь. Когда серебряный кубок оказался на уровне его глаз, возникло какое-то движение, и в полированной поверхности смутно отразилась приближающаяся фигура.

Позвони в технический отдел. - В куполе нет света. - У тебя галлюцинации. Тебе пора отправляться домой.

Потому что это проституция, а она в Испании строжайше запрещена. Доброй ночи, сэр. - Но… Послышался щелчок положенной на рычаг трубки. Беккер беззвучно выругался и повесил трубку.
