New clinical celular trial for treatment of Parkinson’s disease injecting stemcells in the patient brain

A first step to a Parkinson treatment with stem cells. The first clinical trial conducted in China (see HERE) to treat Parkinson’s disease and age-related macular degeneration and the second most common neurodegenerative disorder is to be launched shortly. In the next few...

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...

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...

Pre-embryo. This term is no longer used in current discussions regarding the nature of the embryo

Everything suggests that the term has been artificially created to justify the use of embryos for IVF and biomedical experiments A recent article has studied the use of the term “pre-embryo” (see “Determining whether the preimplantation human embryo is a living...

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...

Genome sequencing in foetal .This prenatal diagnosis arrises a new level of complexity to medical, family and social decisions

Regardless of the legal judgment that abortion deserves in different countries, any action that may induce or facilitate abortion is ethically unacceptable. In 2012, a technique was developed that enabled the foetal genome to be determined in the first trimester of pregnancy,...

Study shows, for the first, time, that chromosomal abnormalities are strongly associated with IVF – assisted reprodution practices

The presence of chromosomal abnormalities in embryos is very high following hormonal ovarian stimulation and in vitro fertilisation (IVF), occasionally exceeding 50%. Regardless of other medical reasons, part of these are thought to be caused by the type of treatment used to...

Review of the last advances in the producing of a functional intestine

A new step has been done to grow something therapeutically useful intestine in the long run (see the last article we published HERE). When it comes to growing intestines, the first inch is the hardest -, especially in a Petri dish. Scientists at Cincinnati Children’s...

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...
