Frozen human embryos are collapsing fertility clinics capacity of storage. Bioethical approach

Frozen embryos abandoned. Short review Earlier this year, CBS News published an interesting review with the evocative title Tens of thousands of embryos are stuck in limbo in fertility clinics, an issue we have addressed several times in our Observatory because it is a great...

Role of the fetal immune system in preterm labor. Upends conventional thinking about immune development

A very interesting article published in EurekAlert! discusses this highly relevant issue. “Preterm labor, a common pregnancy complication, has long been a mystery to scientists. But a new study from UC San Francisco shows it may sometimes happen when the fetal immune syst...

International discussion has been proposed about ethical use of embryoids

An article published in Nature, signed by notable personalities in the area of bioethics, discusses the ethical implications of embryoids (organoids) or embryo models, in vitro cell aggregates that model various regions of the embryo to allow their study. These studies are framed...

Another molecular revolution. The atlas of human embryonic development

We publish the full text of the article published in the Civica magazine last January (Spanish version HERE) that we consider of great bioethical interest. By now, at this advanced stage of biology in which we find ourselves, no one should doubt that each human individual, each...

More facts of the human fertilization process

During the fertilization process, a series of interactions take place between the sperm and the oocyte (egg), with the starting point of the process being the adhesion of the sperm to the membrane of the egg and the subsequent fusion of both cells, a process that involves...

Scientific institutions are trying to devise global safeguards to stop rogue gene-editing of human embryos

Some U.S. researchers knew of a Chinese scientist’s intentions to implant edited embryos but were unable to stop him. A recent article makes an update of the measures that the scientific community is implementing to avoid implantation of edited embryos. It says  Now, nearly two...

The status of person of the human embryo

“The ultimate postmodern injustice is the refusal to recognise certain human individuals as persons” * Introduction The continuing advances of science in the area of embryology leave little doubt about the human nature of the embryo of our species. Biologically, there...

Nature changes its policy allowing experimentation with human embryos. Why?

Nature Group does not explain the reasons for this change. In any case, the question remains if its decision is based on new scientific evidence. Research using human embryos and embryonic stem cells has prompted a fierce ethical debate. As editors of these types of studies, the...

Human-mouse hybrids created with sperm produced from human testicular stem cells

According to a recent article (see HERE), a team of researchers has managed to produce human functional spermatids (as sperm precursor cells are known) from human spermatogonial stem cells (SSC), testicular sperm cell precursors.  The SSCs were isolated and identified...
