Can brain damage be repaired using cell reprogramming? Can be replaced the neurons?

Cell reprogramming (read our report about this technique HERE) has opened great therapeutic possibilities in medicine. Within this field, one of the most attractive possibilities would be to replace neurons that may be destroyed in various illnesses or following a stroke. Now, 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,...

North America’s two cell therapy companies fined for medical fraud. Is it the tip of an iceberg?

The Federal Trade Commission in the United States, has filed its first punitive action against two cell therapy companies. The Regenerative Medical Group and the Telehealth Medical Group offer therapy with stem cells derived from amniotic fluid for autism, cerebral palsy, various...

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,...

Same-sex parents produced in mammals. Mouse pups obtained from “exclusively” male or female pairs

See video below Scientists have managed to produce mouse pups , i.e. bimaternal or bipaternal, in experiments that have been published in Cell Stem Cell. In the aforementioned study, fertile mice were obtained from two females, and mice from two males were born from surrogate...

Cancer cell therapy, still experimental, beats terminal breast cancer woman with secondary cancers

As far as we know, it is the first time that a cancer therapy achieved terminal cancer eliminating all cancer cells  Judy – who lives in Florida – had spreading, advanced breast cancer that could not be treated with conventional therapy. She had tennis ball-sized...

Cardiac muscle cells, that drive the beating of the heart, developed from iPS cells

Cardiomyocytes produced with success One of the possibilities for the clinical-experimental use of iPS cells is to develop human-like tissues -organoids- for use in basic research or in preclinical therapeutic studies. Now, using iPS cells obtained from primates, a team from...

A step to a cancer vaccine. A promising animal trial with autologous iPS cells

 Cancer vaccine advances A new possible use of iPS cells (see medical and ethical advantages of iPS cells treatment) has been opened up, using them as a type of vaccine against cancer. According to a recent study published in journal CELL (see HERE), autologous iPS cells (i.e....

For now, iPS cells have revolutionized the laboratory bench more than bedside

In a recent article, Amélie Rezza discussed the current use of iPS cells, understanding as such adult cells reprogrammed following a technique discovered by Yamanaka. See HERE our site for furthermore information. After the development of these cells, it was thought that they...

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...
