Science is moving at such a rapid speed these days, between cloning, gene
therapy, miracle drugs, exotic therapies, etc. One of the most significant breakthroughs
came in November 1998, when two separate researchers successfully isolated stem
cells from human embryos and aborted fetuses. Stem cells are primordial cells of a
human organism, which are capable of becoming all or most of the 210 different kinds
of tissues in the human body. Stem cells have been defined as not fully differentiated
yet to be any particular type of tissue or cell. They range from "totipotent, i.e. ( the
early stages of the human embryo up to about 4 days after conception.) To pluripotent
I.e. (a bit older and therefore only capable of being some cells or tissues in the
body.) As in the 5-7 day blastocyst stage of the early embryo, with decreasing
capacity in later stages of fetal development and in human beings.
The impassioned hopes are that these stem cells can be used to great
advantages. The cautious fears are that innocent and vulnerable human beings are
destroyed, and needlessly so, in the process.
The debates are raging. Many people are confused about what stem cell research
really is, and wonder why all the fuss. There are several well documented and well-
articulated sources of information available on this issue already, so the following is a
brief overview of some of the major scientific, ethical, pros and cons.
For centuries humanity has been plagued with numerous diseases, such as the
black plague, Cancer, AIDS, and other diseases. These horrific, dreaded diseases
have killed millions of people due to doctors or scientists not having a cure, but thanks
to a scientific and medical breakthrough these diseases can and will be a thing of the
past. With this new research scientists are...
