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...

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...

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...

Mitochondrial replacement used for the first time in viable human embryos

An article has been recently published in scientific journal Nature (534; 383–386, 2016), describing the application of mitochondrial  technique in viable human embryos. This experiment is considered  as the first preclinical study in humans in this field. Mitochondrial...

Human embryos manipulation for possible biomedical uses is permitted. Ethical assessment

It is often said that in scientific research, anything that can be done, will be done, regardless of its ethical connotations. This is what seems to have occurred in the light of an article published on 4th May this year in Nature (doi:10.1038/nature17948), entitled...
