CRISPR. Viable human embryos genetically edited in the USA. Technique and ethical controversies

Numerous complications could go unnoticed in this study On 26th July, the journal MIT Technology Review  announced that the CRISPR technique (see HERE) had been applied in human embryos for the first time in the United States, in a study led by embryologist Shoukhrat Mitalipov of...

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...

Three-parent babies. Two children have been born by mitochondrial transfer technique

We recently discussed mitochondrial transfer in the United Kingdom (see HERE). On 15 December 2016, the UK Human Fertilisation and Embryology Authority approved this technique to prevent the transmission of mitochondrial diseases, i.e. the technique colloquially known as the...

Genetic engineering of human embryos to treat diseases. An unprejudiced reflection

In the last five years, many laboratories worldwide have employed the genetic engineering technique known as CRISPR/Cas9, in the hope that it might one day be used to treat human diseases. Things seem to have accelerated in the last few days though, after the authorisation in the...

Gene editing today. All we have to know about it and our bioethical assessment

Few scientific breakthroughs have been as important as the discovery of the CRISPR/Cas9 (clustered regularly interspaced short palindromic repeats) technique as a gene editing tool. CRISPR/Cas9 is a natural system that provides bacteria with an adaptive response against viruses...

CRISPR used for the first time in humans

A team led by oncologist Lu Youou at Sichuan University in China has become the first to use the revolutionary CRISPR technique on a patient with aggressive lung cancer as part of a clinical trial at the West China Hospital, according to an article published in Nature. The use of...

Functional artificial eggs obtained for the first time from mouse skin

Scientists in Japan have transformed mouse skin cells into eggs and have managed to obtain fertile offspring after their fertilisation (See Nature article HERE). This study represents the first production of eggs completely in vitro. In 2012, mouse skin cells were reprogrammed...

Regenerative medicine. A review of current findings from an ethical perspective

The field of action of regenerative medicine (RM) is growing daily. Indeed, we only have to look at the economic figures that it moves, with an estimated market value for 2020 of 61,000 million Euros. However, RM also has important ethical components, not only related with the...

Cloned animals. Confirmation that cloned sheep can live a long healthy life

After the cloning of Dolly the sheep (the first cloned sheep) 20 years ago this July, the possibility of using this technique to obtain animals that could be exploited for ethically sound purposes has been suggested. However, one problem that has arisen is that Dolly, it seems,...

Death penalty drugs. Now Pfizer refuses to provide drugs for capital punishment in the United States

A few days ago, pharmaceutical giant Pfizer announced a ban on the use of their drugs for capital punishment in the United States. This decision was picked up by American newspaper The New York Times, where the company stated that the manufacture of their products is intended to...
