Stem cells are unspecialized cells that have the potential to develop into any type of cell in the body. They are essential for growth, développement, et réparation. Stem cells can be found in many different parts of the body, y compris la moelle osseuse, cordon ombilical, et tissu adipeux.
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
Il existe deux principaux types de cellules souches: cellules souches embryonnaires et cellules souches adultes.
- Cellules souches embryonnaires are derived from the inner cell mass of a blastocyst. Ils sont pluripotentes, which means that they have the potential to develop into any type of cell in the body.
- Cellules souches adultes are found in many different tissues and organs of the body. They are 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, including cancer, maladie cardiaque, et blessures à la moelle épinière.
