our heart muscle cells from 1% fewerThe heart muscle cells we have when we die are able to regenerate. Usually the heart muscle cells we have are the same from the first month of life, and this means that heart attacks or heart disease can leave the heart permanently vulnerable.

According to a study published in the Journal of Cardiovascular Aging, experiments have shown that cardiac muscle cells can be repaired and can be renewed A technique has emerged. Although tests have only been done on mice so far, if this technique also works in humans, it could potentially pose a risk to people who have had a heart attack. life-saving treatment can be found.

The method is described as an “out-of-the-box” process

In the developed technique, ribonucleic acid, a synthetic precursor, ie mRNA is used. mRNA is the protein we use to build the proteins that make up and regulate our cells. DNA creates a template from folders. The scientists tested the body’s responses by altering the mRNA and giving different instructions for different biological processes.

These regulated instructions are made of various proteins that are mutated, attached to DNA and involved in the regulation of gene expression that promotes its replication. Rod and DO5SA supports the duplication of cardiac excavation cells through

Experiments with both hearts in tissue culture dishes and live mice revealed that Stemin elicits stem cell-like properties in cardiomyocytes, while YAP5SA promotes organ growth and replication. This whole process was done by the research team. “out of the box” is defined as.

Damage from heart attack largely healed within 24 hours

In a study of mice with damaged hearts, nuclei called myocytes were formed after injection of the mutated transcription factors Stemin and YAP5SA. within 24 hours least 15 times observed to increase. This shows that a person who has had a heart attack or heart disease can recover with this method.

It was explained that the main idea of ​​the study was to enable the heart muscle cells, which have a very low regenerative capacity, to behave like stem cells that can be converted by the body into various specialized cells. Biologist Robert Schwartz of the University of Houston, who was part of the research team, said: “For the results of the study,”No one has achieved anything to this extent before and we think it could be a potential cure for humans.” said.

Heart disease, deaths worldwide a quarter to shape. The team continues to work to learn more to see how the body reacts after heart disease and a heart attack. Research continues on whether this method will successfully affect people. The research team knows that they have many years ahead of them to make this method a useful treatment method, but they are confident in it.
