Synthetic Biology. Engineering and biology combined to create a minimal genome

Producing living beings with new characteristics by an artificial synthesis of a minimal genome to then transplant it into a living cell On 24th March this year, an article by Craig Venter and his team was published in Science, in which they described how they obtained an...

Producing human organs in animal chimeras raises objective medical and ethical problems

The major medical and social problems in organ transplantation owing to the increasing shortage of donor organs is well known. Solutions must therefore be sought in the fairly near future that can resolve these issues. One of these is the production of animal chimeras in which...

Genome editing CRISPR-Cas9 technique. Biomedical, ecological and ethical considerations

The real possibility of using this technique for genetic modification of the human germ line, which could have serious and unpredictable consequences in the individuals treated and their offspring; it could also definitively lead to the introduction of transhumanism in society....

Human embryo and its mother. Their dialogue extends to the genomic area

A key issue in the Masters in Bioethics taught at our Catholic University is the “biological status of the human embryo”, because demonstrating that the early human embryo (from the blastocyst phase) is a biological being of our species and not a uniform cluster of...

New steps towards the production of human cell lines

In 2013, Mitalipov’s group published an impressive study (Cell 153; 1228-1238, 2013) in which they reported the production of human blastocysts, and how embryonic human cell lines could be derived from them, and from these, cells of various tissues. Regardless of the ethical...

Why monozygotic twins, birth with identical DNA, are different. Do epigenetic mechanisms influence gene expression?

Epigenetic mechanisms have a real influence on the expression of the genome Why monozygotic twins with identical DNA are different. Gene expression can be conditioned by epigenetic mechanisms arising from the genome’s interaction with the environment. These mechanisms influence...
