With the aim to find a new sources of organs for transplantation, Japan approves the first human-animal embryo experiments. Positive and negative apects

Scientist Hiromitsu Nakauchi is the first researcher in Japan to receive permission from the government to create animal embryos that contain human cells human-animal chimeras and transplant them into surrogate animals for gestation, as explained in an article in the journal...

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...

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...

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....

Artificial organoids generated from cancer cells

Organoids mimic therapies responses We have published several articles about Potential applications of organoids that mimic different organs. We concluded that this creation of organic structures (organoids) similar to others in our body may have objective biomedical...

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...

iPS cells are also used to gain in depth knowledge of diseases. Now Parkinson disease is being more studied in depth by this technique

It appears to have been confirmed that the α-Synuclein gene is the one primarily linked to Parkinson’s disease, while the G209 (p.A53T) mutation of this gene causes a type of Parkinson’s disease characterized by early and severe onset of symptoms. It has now been...

First major step in the treatment of blood diseases from adult cells

Researchers at Weill Cornell Medicine  have developed an innovative method for obtaining blood cells (adult cells) from the endothelial cells of blood vessels (see HERE) to imporove blood diseases treatment. A peculiar characteristic of this technique is that abundant blood cells...

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...
