Pluripotent stem cells used for regenrative medicine risks. They can develop mutations that favor the production of cancer cells

It should be crucial to check pluripotent cell lines (embryonic and iPS cells) before clinical testing before their use in regenerative medicine The production of pluripotent stem cells, from which virtually all types of cells can be obtained, may be of great use for the...

The future of iPS – induced pluripotent stem cells. New finding increases tremendously their potential for clinical use

Cells now can be obtained from anonymous donors, however, and stored in a cell bank, the costs would be reduced significantly, and their potential for clinical use would increase tremendously A recent article published in Nature discussed some specific aspects regarding the...

A short review of negative and positive effects of Trump’s restrictions on fetal tissue research

As we published recently (read HERE), the American Administration has placed restrictions on research using fetal tissue, giving rise to a fierce debate among researchers. In this respect, Judd Deere, deputy White House press secretary told Science that enacting the new poli...

Current treatment of transgender youth includes the suppression of puberty that has direct consequences on the development of the minor.

A relevant ethical, moral and legal medical unresolved issue is the current treatment suppressing puberty of diagnosticated transgender children. Has it direct consequences on the development of the minor? We extracted a topic from a peer-reviewed large Spanish study which make a...

Eggs and sperm could be produced from female blood samples

The journal Science has published an interesting article  by a Japanese group, led by Mitonori Saitou, which describes the production of oogonia from female blood cells. According to Carlos Simón, an expert in this area (see HERE ), “a mature oocyte has not yet been obtained,...

In vivo cell reprogramming. A major step forward in regenerative medicine

Cell reprogramming  is revolutionizing the biomedical world, not only because it can obtain cells of different tissues from pluripotent cells, but also because these cells can be genetically modified to be used for the treatment of serious illnesses or to better understand them,...

Neuroscience. New experiments with brain rekindle the bioethical debate

Neuroscience research, with the ultimate goal of deepening our knowledge of the human brain, about which we still know so little, is advancing rapidly (see HERE). Thus, major projects such as the “BRAIN Initiative” in the United States and the Human Brain Project (HBP) in Europe...

Pulmonary organoids produced from human iPS cells in three dimensions (3D)

Lung organoids have been produced from human pluripotent stem (iPS) cells that contain various components of lung tissue, and even airways and alveolar structures (see HERE). Recapitulation of lung development from human pluripotent stem cells (hPSCs) in three dimensions (3D)...

Ten years since the discovery of iPS cells. The current state of their clinical application

Stem cell research. The two sides of the coin

Science facing market The “heads” of stem cell research Stem cells today represent a great hope for the future of regenerative medicine due to their ability to differentiate into cell lines of almost any tissue, making them a promising therapeutic option for many...
