Coming breakthrough in regenerative medicine. Soon you will be able to use stem cells for the treatment in many complex diseases. This technique is essential to extend our life.
Researchers from the University of new South Wales were able to reprogram cells in bone stem cells, able to regenerate many types of tissues. This technique has proved to be in mice and in a few years could be widely used in humans.
Most of the currently developed therapies using stem cells is ineffective in creating new tissues. There are also serious ethical concerns associated with the use of embryonic stem cells to regenerate organs.
Embryonic stem cells may not be used for the treatment of damaged tissues due to their ability to form tumors. The second major issue is the need to use viruses to the transformation of somatic cells in the home, which is a clinically unacceptable, said Dr. Vashe Chandrakantham, co-author of the study.
The technique used by the researchers at the National Australian University allows you to create induced pluripotent stem cells (iPS) without worrying about the transformation of cancer. All because the adult human fat cells be considered a compound called 5-azacytydnz (AZA) and plated AB growth factor (PDGF-AB) in 2 days. Then for 3 weeks work to improve PDGF-AB. Such combination of cleaning, activates cell transformation. The resulting iPS are injected into the damaged tissue, causing a loss in regeneration.
The researchers are planning clinical tests of innovative methods in the next year. This type of treatment can be used to regenerate any human tissue, and thus to revolutionize medicine.
