What are the different types of stem cells?
Embryonic stem cells, in the middle of the figure, can become three other types of stem cells: ectodermal, endodermal, or mesodermal stem cells. Ectodermal stem cells become skin cells and neurons (brain cells), and endodermal stem cells become lung cells, thyroid cells and cells of the pancreas.
How do stem cells work?
Specialized types of stem cells have the ability to stop immune responses. Stem cells may therefore be very useful as a therapy for diseases in which organs are damaged or where the immune system is too active. Some types of stem cells are already used for therapy, such as the hematopoietic (blood) stem cells, which are used for the treatment of bone marrow cancer. The use of other types of stem cells is currently being studied in the laboratory and in experimental therapies. Researchers are trying to find out the best way of giving stem cells to patients, where the cells go in the body, and how long they survive in the patient. We expect that, in the future, many more stem cell therapies will become available.
Why are stem cells important?
Stem cells may therefore be very useful as a therapy for diseases in which organs are damaged or where the immune system is too active. Some types of stem cells are already used for therapy, such as the hematopoietic (blood) stem cells, which are used for the treatment of bone marrow cancer.
What organs do stem cells form?
Altogether, stem cells form all the organs and tissues in the body, such as the bones, kidneys, liver, blood, and brain. After birth, embryonic stem cells are no longer present in the body. However, even in the bodies of children, adults, and elderly people, we find several types of stem cells.

The outer layers of the skin are also continuously renewed, and skin stem cells are responsible for this process. Finally, throughout the body we can find so-called mesenchymal stem cells. Cell that forms fat cells, bone cells, cartilage cells, and muscle cells. . These cells form bone, cartilage, fat, and muscle.
Where are mesenchymal stem cells found?
Mesenchymal stem cells are found in any organ you can think of, including bone, fat tissue, lungs, heart, and brain. The function of mesenchymal stem cells is, first, to repair the body by developing into cells that form connective tissue, fat tissue, and bone tissue.

Stem cells differ from other kinds of cells in the body. All stem cells regardless of their source have three general properties: They are unspecialized; one of the fundamental properties of a stem cell is that it does not have any tissue-specific structures that allow it to perform specialized functions. They can give rise to specialized cell ...
