Stammzellen sind unspezialisierte Zellen, die das Potenzial haben, sich zu jedem Zelltyp im Körper zu entwickeln. They are essential for growth, Entwicklung, and repair. Stem cells can be found in many different parts of the body, including the bone marrow, Nabelschnur, und Fettgewebe.
The Origin of Stem Cells
Stem cells are derived from the inner cell mass of a blastocyst, which is a hollow ball of cells that forms during the early stages of embryonic development. The inner cell mass gives rise to all of the tissues and organs of the body.
Sources of Stem Cells
There are two main types of stem cells: embryonale Stammzellen und adulte Stammzellen.
- Embryonale Stammzellen are derived from the inner cell mass of a blastocyst. Sie sind pluripotent, which means that they have the potential to develop into any type of cell in the body.
- Adulte Stammzellen are found in many different tissues and organs of the body. Sie sind multipotent, which means that they have the potential to develop into a limited number of cell types.
Stem cells are a valuable source of new cells for transplantation and regenerative medicine. They have the potential to be used to treat a wide range of diseases and conditions, einschließlich Krebs, Herzkrankheit, und Rückenmarksverletzungen.
