Healing with stem cells - the biggest mistake of medicine?

Six years ago, the prestigious science journal "Science" recognized stem cells as the best scientific achievements. But the latest research proves that scientists are overly optimistic.

Stem cell research

Despite huge investments in research and applications, stem cells can prove a useless form of material.

According to the assessment of TS. Orly Lacham-Kaplan of Monash Immunology and Stem Cell Laboratories, at least need about ten years, before it can be known, whether stem cells can be safely applied to humans.

Germ cancer

Stem cells are a tremendous hope of medicine, because they can transform into any cell of the body. Theoretically, all can come from stem cells: from egg cells, new bone, capillaries and liver, to brain cells.

Unfortunately, more and more research has shown that stem cells, the culprits that produce all kinds of cancers - especially brain cancer - are more and more common in children.

Breast tumors can grow and spread to other parts only in the case of stem cell capillaries and "scaffolding" products.

As the latest discovery by scientists from Colunbia University, from spinal cord cells with disabilities, not only blood cancers arise, but also stomach cancer.

" We are forced to change the traditional view of the development of all cancers. Instead of just destroying cancer cells, we need to destroy stem cells ". Research program leader Timothy Wang said.

Patients who have received bone marrow transplants from other people are well aware of the dangers of using strange cells. It carries a significant part of the immune-factor system instead of contributing to treating the recipient, attacking the host cell again (called an anti-body reaction).

It is well known that, in subjects with a full blood stem cell transplant, there are often dangerous complications such as sexual dysfunction and rib muscles. Researchers still do not know, why such a phenomenon is present, no one seems to have predicted the disastrous consequences of using cell cultures in the laboratory.

Single reproduction of disabilities

The most problematic issue of current researchers is finding the source of stem cell embryos. Taking them from embryos that appear by in vitro fertilization was condemned by bioethics and banned in many countries.

Scientists at the Roslin Institute Scotland, which cloned Dolly the sheep, announced not too long ago that they had six human embryos from egg cells by a single reproductive method.

This phenomenon is often seen in nature, in some organisms, including bees, ants, shrimp, geckos, and even turkeys. But for mammals, it is a completely unnatural problem - people catch egg cells to "fertilize" themselves with the help of electric waves or chemical elements.

So, according to a large number of scientific people, stem cells that appear by a reproductive method cannot be a true embryo, since it will not develop any body.

The phenomenon of human embryos produced by cloning or reproductive monopaths only sustains survival for a few days or more may be an alarm signal ignored by many researchers.

GS. Richard Doerflinger, representative of the Catholic Patriarch Union, said that development disorders often occur due to genetic defects. The above embryos may be those with serious illness - those that have been created completely unnecessary.

According to other statistics, on average, every four animals now successfully clone, one is a victim of all diseases, including hypertrophy, diabetes, asthma, cirrhosis, heart defects and kidney.

Modest lesson

In 2001, when researchers read the entire human gene map, many futurists affirmed that we discovered the greatest secret of creation - our bodies appear and play. how to develop Within a few years, gene therapy allowed the treatment of countless diseases, but most trials failed.

"The reality increasingly shows that the development of the human body is influenced by many factors outside the gene, which science has not known" -TS. Ian Stewart and Jack Cohen, authored the book "The Breakup of Chaos", affirmed.

In the case of stem cells, the creature once again teaches scientists the lesson of humility — still thinking of finding a way to deceive creation.
