Successfully creating a heart beating 50 beats per minute in the laboratory will open a new path for studying organ donation for patients.

The process of creating an artificial heart

Scientists are always exploring, opening up new ways to create organs for donating patients. Also with this goal, American scientists conducted research to create a heart beating in the laboratory.

According to experts from the University of Minnesota, with the successful implementation of this experiment, this will be a new hope for us to be able to create organs suitable for patients without being too dependent on donated organs. give . Specifically, the experts have conducted the following steps.

First, Dr. Doris Taylor of the University of Minnesota and colleagues selected the hearts of a healthy but lost rat to perform the experiment.

Later, she and her colleagues conducted a process called decellularization to purify the cells available in this heart and only retain the basic collagen structure intact .

Next, they injected this "frame" of heart cells from newborn mice , fed them with nutrient-rich solutions and left them "big" in the lab.

Unexpectedly, four days after the experiment, the heart began to contract.

The team continues to use a device that coordinates this contraction . Specifically, they attach a pump to the heart and fill it with liquid, then compress it slightly to "fool" the heart that is blood pressure.

And then eight days later, these artificial hearts began pumping themselves .

These hearts beat at speeds of 40-50 beats per minute . According to experts, this success will open a new path for them to continue to study the creation of human hearts and more closely monitor the reaction of the heart to drugs.
