When we developed the ability to convert various cells into stem cells, it has maintained a completely new type of treatment. Instead of fixing cells to the body or trying to deal with organ transplant complications, some adult cells were converted into stem cells and induced to form tissue in the body. The patient’s own cells can be repaired or replaced with infinite supply.
However, the induced stem cell Nobel Prize was distributed more than 10 years ago, and the treatment was delayed. However, German researchers are currently explaining the tests of primates in how to repair the heart using new muscles generated from stem cells. The result is promising even if we haven’t provided everything we want. However, they are sufficient to start clinical trials, and similar results are seen in humans.
Heart problem
The heart contains many special tissues, including tissue, which forms blood vessels and specialized in the conduction of electrical signals. However, the key to the heart is a type of special muscle cells called cardiomyus cells. When the heart mature, the heart cells stop division. In other words, it is a fixed group. Due to injury or infection is not repaired. In other words, damage is cumulative.
This is a problem in the case of blocked blood vessels, which repeats the large area of the heart of oxygen and nutrients and kills cardiomyocytes there. This can lead to a decrease in heart function and eventually die.
However, it turns out that converting the induced pluripotent stem cells is relatively easy (IPSC, pluration means that all cells can form). For this reason, researchers tried to inject these stem cells derived into the damaged heart, hoping to incorporate them into damaged tissue. However, these experiments did not always provide clear advantages to animals.
