**What’s the difference between adult stem cells and embryonic stem cells?**

More Information Available on: Adult Stem Cells

Embryonic Stem Cells-



 * = **Embryonic Stem Cells ** ||= **Similarities ** ||= ** Adult Stem Cells ** ||
 * < Embryonic stem cells are found in the inner cell mass of the blastocyst. ||< Stem cells divide without limit ||< The origin of adult stem cells is unknown ||
 * < Embryonic stem cells are pluripotent and can become all types of body cells. ||< Stem cells are able to differentiate into more than one cell type. ||< The differentiation of an adult stem cells differentiation is limited by its lineage. ||
 * < Embryonic stem cells can be easily cultured. ||<  ||< Adult stem cells are difficult to isolate because they are rare in mature tissue. Unforunately, stem cell replacement therapies requires a large number of cells and methods to culture adult stem cells have not worked. ||
 * < Embryonic stem cells from a donor may cause transplant rejection. ||<  ||< Adult stem cells can be advantageous because it stems from that patient's own cells. These cells would not be rejected. ||
 * < The use of embryonic stem cells is controversial. ||<  ||< <span style="font-family: Arial,Helvetica,sans-serif; font-size: 10pt;">The use of adult stem cells stirs up less controversy. No "life" is destroyed. ||
 * Fresh start to make new cells that are not infected. ||  || Adult stem cells have not yet been found in all tissues of the body yet. Also, those cells that do exist may have been infected by the illness as the other cells have. ||
 * Long lasting thus has capacity to produce a wide range of specialised cells. ||  || Shorter lifespan. ||
