How Stem Cells Work

The big discoveries related to stem cells have issued a real tsunami wave of debates. Stem cells are unspecialized cells that have the extraordinary capacity to develop into any kind of specialized cells necessary in the body, not to mention the fact that they have the capacity to renew themselves through division over and over again, even after being inactive for a long period of time. Thus, stem cells can contribute to internal organ repair or to the regrowth of damaged tissues, and the most daring research attempts are in the domain of red blood cells or nervous cell regeneration.

Stem cells seem to work great for the repairs necessary to the bone marrow, but so far, only partly success has been reported for research conducted in heart and pancreatic stem cell division. The major types of stem cells used in laboratories are embryonic and adult, which clearly designates where the biological material is extracted from. The studies with the embryonic ones date back to the early 80s when mouse cells were used for lab testing. These first investigations made it possible for scientists to discover methods of collecting human stem cells that can be afterwards grown in artificial cultures.

Although a controversial issue, the use of the human embryonic stem cells in lab tests are considered by some people the only way to push medical science forward. The embryos result from in vitro fertilization projects, since only part of the embryos can get transferred and implanted in a womb. The embryos that are no longer needed for implantation in the uterus, can be passed to laboratory studies if the donor gives his/her consent. Another source of stem cells is the use of somatic cells that are reprogrammed to return to the initial unspecialized state.

The main moral concern is that of harming embryos, that are considered alive in spirit and not only in the physical form alone. Banned during the Bush administration, the stem cells research has been re-opened in March 2009 by president Obama. On the other hand, the importance of stem cells is overwhelming if we consider what huge opportunities it opens for the treatment of diseases such as diabetes, leukemia, Parkinson’s disease and so on. However, stem cell therapies are not fully known or available because this part of regenerative medicine has a lot more to unravel before becoming fully operational, safe and effective.
