The concept of stem cells is more and more widely debated outside the medical circles where it started from. 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 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.
Scientific medical success has been reported for the repair and replacement of damaged cells in the bone marrow, but so far, stem cells have been only partly able to divide in the heart or the pancreas. There are two types of stem cells used in scientific research and medical applications: embryonic stem cells and adult stem cells. The studies with the embryonic ones date back to the early 80s when mouse embryos allowed for superior biological research. These first investigations enabled scientists to discover 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. Most of the studies are conducted on embryos created as part of infertility programs adjacent to in vitro fertilization techniques. The embryos that are no longer needed for implantation in the uterus, can be p***ed 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.

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, the medical world is just taking the first steps towards understanding how regenerative and reparative medicine could work with the help of cell-based therapies.
