Stem Cells: Life’s Basic Building Blocks
September 1st, 2010
The big discoveries related to stem cells have issued a real tsunami wave of debates. Stem cells represent those cells that have not received a body function yet; they either remain inactive in the tissues until it’s time for them to regenerate the body after disease or injury, or they gradually develop their body tasks according to the genetic evolution of the embryos. Thus, stem cells can contribute to damaged tissues regrowth or internal organ repair, and the most advanced 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. There are two types of stem cells used in scientific research and medical applications: embryonic stem cells and adult stem cells. The studies on embryos started back in the early 80s when mouse embryos allowed for superior biological research. These first investigations enabled scientists to come up with methods of collecting human stem cells that can be afterwards grown in artificial cultures.

Although a controversial issue, embryonic stem cells represent the best viable option to push medical knowledge beyond its present limits. The embryos result from in vitro fertilization projects, since only part of the embryos can get transferred and implanted in a womb. The remaining embryos can be passed to laboratory studies if the donor gives his/her consent. A new stage in the research of stem cells was marked in 2006 when scientists discovered a method of reprogramming certain adult cells to behave like stem cells.

If this practice proves successful and useful, worries will stop concerning the legitimacy of lab tests on human embryos. Banned during the Bush administration, the stem cells research has been re-opened in March 2009 by president Obama. Stem cells do remain the main hope of many health care providers in the fight against devastating diseases such as Parkinson’s, Alzheimer, diabetes, leukemia, heart failure and lots of others. 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.
