Emphysema - Harvard Health

I posted Dr. Fernandez Vina and it consists of the following:. The lungs grab and keep the stem cells and the alveolus starts regenerating. What happens here is that dead cells in the alveolus of the lungs leave empty spaces or niches or little caves, into which the stem cells settle down and start growing, reproducing and rebuilding the alveolus. The stem cells go to the lungs directly as all blood passes through the lungs before going to the heart, lungs are a sort of a trap and the stem cells stay there.

Types of Stem Cells

Stem cells are the most basic type of cell. They give rise to all cells with specialized functions, such as blood, bone, brain and heart cells. They are also capable of dividing and self-renewing for long periods of time. These features make them different from any other type of human cell.

Normally, when you take a breath, air travels from your nose and mouth through your windpipe and into the bronchi. These are small air passages that branch off into each lung. The bronchi branch further into thousands of smaller, thinner tubes that end in grape-like clusters of small, round air sacs called alveoli.
