What is the life span of a stem cell?

Answer 1

The knowledge of the life span of stem cells is critical in bone-marrow transplantation and in cancer treatment. Earlier it was believed that these cells can grow for indefinite period of time.

But, a new computer simulation carried by the researchers from Sanford-Burnham Medical Research Institute (Sanford-Burnham) has found that stem cells can survive from a few months to several years.

They cannot self renew themselves for the entire life span of a patient.

The results of the mathematical modeling were published in the February 28, 2011 weekly edition of the Proceedings of the National Academy of Sciences.

The simulation was carried out using the stem cells of experimental mice. The research revealed that self renewal of stem cells is regulated by maintaining a dangerous and uncertain balance. It is because excess production of these cells can lead to blood cancer and their less production can cause failure of the bone marrow transplantation.

Answer 2

The lifespan of a stem cell can vary depending on the type and origin of the cell. Some stem cells have the ability to self-renew indefinitely, while others have a limited lifespan. In general, stem cells can remain active and functional for years under the right conditions.

Answer 3

Define Die all cells eventually Die. But with stem cells their main objective is to form and complete the fetus and make daughter cells to grow tissue and life.

Answer 4

60 days
