After a recent study, scientist may have found a stem cell in the human lung. The stem cell found was capable of making a large amount of the organ’s tissue. To find out if the cell is really a stem cell, scientists tested it out on mice. They punctured the lungs of twenty-nine mice. Then, they injected the six doses of twenty thousand cells into the mice. Within the next ten to fourteen days, the cells that were injected created new airways, blood vessels, and air sacs in all of the mice. This showed a huge difference. The stem cells produced millions of new cells in a very short time. With this new discovery, scientists may be able treat deadly lung diseases, such as emphysema. It may also be able to treat pulmonary hypertension, which is high blood pressure in lungs’ arteries. Another way stem cells could be used is to help the lung recover after lung cancer surgery. However, scientists are not sure on whether the lung stem cell could help with asthma.I find this to be a remarkable discovery that will change the face of medicine. Finally, we may have found a cure for fatal diseases like emphysema. This disease kills thousands of people every year. To have a cure for it is amazing. Although scientists aren’t sure on what diseases it will cure, it is up to our generations to find out. The stem cell discovery shows that technology is drastically improving. With this discovery, emphysema and other lung diseases will soon be a joke.
