Stem Cell Are Commonly Known

Stem cell are commonly known as the "master" cells which can develop into any type of cell -- skin, bone, blood etc. Moreover, stem cells are the building blocks of bone marrow. It is understood that the stem cell, under the influence of various growth factors, differentiates and provides all the types of blood cells needed. From studies and research taken, stem cells are then believed to have the potential to provide perfect-match tissue for transplantation and in the treatment of diseases such as Parkinson's (http://arts.usask.ca/policynut/courses/soc292-8.ppt,2006).

On August 9, 2001, President George Bush announced that NIH would fund human embryonic stem cell (HESC) research for the first time. The research will be restricted to 72 cell lines derived from surplus fertilized embryos before August 9 (Young, 2006). But this created numerous great debates over some concerned citizens. Both opponents and supporters of HESC research are unhappy with the ruling. Opponents believe that federal funding of human ESC research will open a Pandora's Box leading to baby and organ factories. Supporters believe that the restrictions will hold back crucial research that will benefit millions of people (Young, 2006).

Researchers have recently found that they can create cloned embryos.

Stem cells derived from such embryos have the same genes and are an ideal source of stem cells for transplantation. Congress, however, is considering a bill that would outlaw making of cloned embryonic stem cells (Young, 2006).

This endeavor is truly a big leap forward in the advancement of science and technology, and medical and human aspects are some of the few factors that will be greatly benefited. Study of human embryonic stem cell will lead to major advances in human biology, specifically:

Embryonic stem cell research will provide critical insights into mechanisms of cell differentiation, growth, and death (Young, 2006).

Understanding stem cells may provide keys to why people age (Young, 2006).
