3 different types of stem cells


Science was able to distinguish 3 different types of stem cells.

• Totipotenciales.
Are the most versatile of all stem cells. Of them can get a whole organism. The only problem is that only they can be purchased in the early stages of an embryo.

• pluripotential.
Wildcards cell. These cells can become different kinds of tissues, but they alone are incapable of generating a complete organism.

• Multipotenciales.
Because cells are quite distinct, and they are specialized to produce a tissue or cell type in particular. Haematopoietic stem cells, for example, found in bone marrow, can produce different types of cells, all related to the blood: red cells, platelets and white blood cells. Although further research have already obtained cardiac tissue from them.
