Understanding the biological mechanisms of aging. Aging retardation is achieved in mice

A biological topic of great interest is to understand the mechanisms of aging. The nervous system is known to clearly affect aging, especially the hypothalamus, but the mechanism by which it occurs is presently unknown. Cells that had been genetically engineered to survive in the...

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...

Cells from human umbilical cord blood revitalized part of aged rats’ brain

Cord blood stem cells revitalized part of the brain in aged rats. Umbilical cord blood is known to contain stem cells that can be used for different clinical objectives  (see HERE), especially in the promotion of cell banks. Now, a new possibility for the use of umbilical cord...

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)...

Reproductive medicine and the production of bioartificial organs

Reproductive medicine and the production of bioartificial organs may be a source of hope in the next few years for patients with degenerative lesions of various organs, among them the reproductive organs. Undoubtedly, in this respect, major advances in stem cell knowledge,...

Intestinal tissue produced from embryonic stem cells and iPS cells

The intestinal nervous system controls several functions of the gastrointestinal tract, and when impaired causes bowel abnormalities. Now, a group of American researchers has generated intestinal tissue from embryonic and iPS cells (this last hasn’t ethics problems), using...

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...

Regenerative medicine. A review of current findings from an ethical perspective

The field of action of regenerative medicine (RM) is growing daily. Indeed, we only have to look at the economic figures that it moves, with an estimated market value for 2020 of 61,000 million Euros. However, RM also has important ethical components, not only related with 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...
