New method to create human stem cells

US scientists have found a new way to create human stem cells, allowing the replacement of embryonic stem cells to treat diseases.

The results of this important study are published on September 30. According to Harvard Medical University scientist Derrick Rossi, the lead researcher, stem cells created by the new method do not require genetic changes that are potentially risky and promise more efficacy during treatment sick.

Instead of adopting the traditional genetic modification method to produce proteins that can reprogram mature cells into reproductive stem cells (iPSC), scientists have developed The molecular chain of information synthesizes modified RNA (also called modified RNA) to encode proteins, but does not merge with cellular DNA.

They found that managing modified RNAs accelerated the reprogramming of proteins in mature skin cells, which later turned into iPSCs.

Also according to the study, iPSCs with an RNA chain linked to muscle cell development have made cells differentiated into muscle cells. This distinction is simple, effective and without the risk of mutation.

Stem cells, also called stem cells, are primordial cells capable of differentiating and developing into any of the 220 cells in the body.

This ability allows them to act as a " repair " system in the body, compensating for the dead cells throughout the life of each organism.

To get stem cells, scientists have to destroy a few-day-old embryo. This is one of the main reasons for the controversial ethics of the stem cell research program for many years.

Stem cells can be used to achieve medical advances to treat incurable diseases such as cancer, cardiovascular disease, diabetes, dementia (Alzheimer's) or paralysis ( Parkinson's), or treatment of spinal injuries.
