Legal status of human-animal chimeras – hybrid embryos

In addition to the biomedical and bioethical problems raised by human-animal hybridization, there are also objective legal problems. A recent article in the Journal of Medical Ethics (2014; 40, 284-285) reviewed this topic following a debate in the United Kingdom (UK) House of...

The amazing finding of senescent cells in embryos. Until now, these cells had been found only in aging tissue

The discovery raises the possibility that the start and end of life are intimately connected The process by which cells cease multiplying is known as senescence. In 1961, biologists Hayflick and Moorehead cryoconserved human fetal cells and found that these divide around 50 times...

Genome sequencing in foetal .This prenatal diagnosis arrises a new level of complexity to medical, family and social decisions

Regardless of the legal judgment that abortion deserves in different countries, any action that may induce or facilitate abortion is ethically unacceptable. In 2012, a technique was developed that enabled the foetal genome to be determined in the first trimester of pregnancy,...

Study shows, for the first, time, that chromosomal abnormalities are strongly associated with IVF – assisted reprodution practices

The presence of chromosomal abnormalities in embryos is very high following hormonal ovarian stimulation and in vitro fertilisation (IVF), occasionally exceeding 50%. Regardless of other medical reasons, part of these are thought to be caused by the type of treatment used to...

Review of the last advances in the producing of a functional intestine

A new step has been done to grow something therapeutically useful intestine in the long run (see the last article we published HERE). When it comes to growing intestines, the first inch is the hardest -, especially in a Petri dish. Scientists at Cincinnati Children’s...

The biological status of the early human embryo. When does human life begins?

“Those who argue that that embryo can be destroyed with impunity will have to prove that this newly created life is not human. And no-one, to the best of our knowledge, has yet been able to do so.” Introduction In order to determine the nature of the human embryo, we need to know...

Ten years since the discovery of iPS cells. The current state of their clinical application

CRISPR used in viable human embryos and germline genetic modification. An ethical approach

From an ethical point of view, the use and destruction of human embryos, members of our species and worthy of full dignity is completely unacceptable and, it should be noted,  these experiments involve genetic modification of the germline, the safety of which is still far from...

Intestinal tissue produced from embryonic stem cells and iPS cells

The intestinal nervous system controls several functions of the gastrointestinal tract, and when impaired causes bowel abnormalities. Now, a group of American researchers has generated intestinal tissue from embryonic and iPS cells (this last hasn’t ethics problems), using...

Is the human embryo a living being of our species?

Few doubts that determining whether the preimplantation human embryo is a living being of our species is one of, if not the most, fundamental issues in modern bioethics. Another thing is whether that living biological being is, or is not, a human person. That, however, is another...
