Understanding the Biological Function of Adult Stem Cells

Home

Because of the plethora of recent developments and discoveries in the field of non-embryonic stem cell research, now might be a good time to refresh memories on the biological function of adult stem cells. At their most basic, stem cells have the ability to divide ad infinitum and have a capability to develop into one or several different types of the 220 cells that are known in the human body.
The integumentary system, more commonly known as the skin, has the potential to replenish itself from the day we are born until the day we die. This capability has long intrigued scientists looking for ways to replace damaged or dead cells in other organs of the body as well as to help replace damaged cells in those suffering from diseases such as diabetes, Parkinson's, and various forms of cancer. Another body cell that is able to reproduce in such a way is the stem cell found in bone marrow. Liver cells replenish and "reproduce" cells within 10 to 15 days. White blood cells reproduce every one to three days.

Understanding the reproduction or replication of adult stem cells has been at the basis of seeking methods to replicate their growth and to pinpoint ways to help those types of stem cells differentiate, or grow, into the type of stem cell that is needed for the treatment of diseases and illnesses. Further studies will continue until scientists and researchers are satisfied that they understand exactly how these cells work.
