The human embryo mapped in three dimensions. Technique and bioethical approach

A team of researchers from the Institut Vision in Paris and the Jean-Pierre Aubert Research Centre, under the direction of Alain Chedotal, have managed to map the human embryo  in three dimensions (see HERE the published study), which, they believe, permit better understanding of...

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...
