Human lung stem cells are able to replicate themselves

US scientists say they have established human lung stem cells capable of replicating themselves as well as forming and binding the multi-biological structures of the lungs.

This is the first time researchers have established this type of cell, opening up the hope of successful research on effective treatments for incurable lung diseases.

Center for Regenerative Medicine Brigham (Brigham, USA) used lung tissue to identify and isolate it, according to a study published in the May 12 Journal of Medicine in the New England Journal of Medicine. Human lung stem cells, then study the function of this type of cell in vitro as well as in culture medium.

When stem cells are isolated, it is capable of dividing into new stem cells and forming cells that can develop into different tissues of the lungs. Next, experiments on mice showed that stem cells, after being damaged in the lungs, did not only develop into new cells forming new lung tissue but also linking the structure to the tissues. lungs available.

From this result, researchers confirmed that this is indeed a stem cell because it meets three criteria, that is, the ability to self-replicate, which can develop into many types of lung cells and be able to mutate. Genetics, ie after transplanting a human lung stem cell into a mouse to produce new tissues, scientists can isolate new stem cells, then continue to implant another mouse. and also achieved similar results.

According to the researchers, these are extremely important findings for the study of treatments for incurable diseases of the lungs.

For years, research using stem cell therapy in the treatment of lung diseases is less of a concern for scientists because the lungs are a complex organ, made up of many types of cells that can replicate in the Different levels.

According to the National Institute of Medicine, lung diseases are the third largest cause of death in the United States after cardiovascular disease and cancer.
