Infertility treatment.”The best option for endometrial regeneration in patients with Asherman’s syndrome.” Asherman’s syndrome is an acquired uterine abnormality characterised by the presence of intrauterine adhesions, and which clinically causes...

Retinal tissue produced from iPS cells in animals

One of the possible applications of iPS cells is in the treatment of retinal diseases. Now, a group of researchers from the Riken Institute in Kobe (Japan) see HERE has presented some interesting experiments in which they were able to produce retinal tissue from iPS cells (iPS...

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...

Cell therapy clinics questioned. Technical and ethical aptitude of clincs in North America

Today in the United States there are 350 cell therapy centres offering stem cell-based treatments for autism, cystic fibrosis, multiple sclerosis and other diseases. Cell therapy clinics questioned because the vast majority lack not only approval by the United States medicines...

Experimental production of funcional spermatozoa in mice

“Could this technique also be performed in humans to treat infertility problems without ethical problems?” A major step has been taken in the experimental production of spermatozoa, after a Chinese team were able to produce them “in vitro” from mice (Cell...

Stem cells and the production of organoids at the forefront of biomedical science

There are topics in which biomedical interest merges with ethical interest. One of these is undoubtedly the subject of stem cells wich appears to be the biomedical science forefront. Few issues in the biomedical sciences arouse as much interest as these, and for this reason, the...

Umbilical cord blood banks. What is the ideal type?

Since umbilical cord blood banks were first used for stem cell transplants, their number has been increasing permanently worldwide. There are currently three types of umbilical cord blood banks: public, private and mixed. In the public banks, samples are at the disposal of any...

Can human iPS cells replace the use of human embryonic stem cells?

A hotly debated topic within the specialised scientific world is whether or not human iPS cells are similar to human embryonic cells, which raise too so many ethical issues. It is a mistake to believe that this, in principle, is a problem with exclusively technical implications,...

iPS cells derived from HIV-resistant individuals for the treatment of HIV infection

New technique: It involves iPS cells from HIV-resistant individuals for the treatment of people infected  Some people have a mutation in their genome (CCR5A32) that gives them certain resistance to HIV infection. Taking advantage of this situation, a step has now been taken that...

Fraudulent cell therapies. They must be subject to medical evidence

Fraudulent cell therapy an objective ethics problem in biomedicine One major ethical problem in the field of cell therapy is the fraud that can be committed by proposing the use of treatments that have not been proven to be clinically effective. This fraud can be especially...
