Stem Cells

Few scientific issues in recent years have managed to draw as much attention, both scientific and otherwise, than stem cell research. I was first introduced to the term ‘stem cells’ when I was in high school, and since then, I have had a keen interest in the direction science is taking them. When considering medical research as a whole, stem cells appear to have the makings of a 21st century medical revolution a la discovery of antibiotics . The open-ended nature of stems cells has been recognized by many in the community who see these cells as the golden key for curing and ameliorating many degenerative diseases such as diabetes, Parkinson’s, and heart disease, as well as accidental damage such as a spinal cord injury. Clearly, stem cells hold a great deal of promise in medical research and I feel that being more than casually aware of something that will greatly affect health care and my future studies if I chose to pursue medical research in graduate school, is critical. Unfortunately, having not had the occasion to do my own research on the subject, I feel this assignment presents the perfect opportunity (and encouragement) to explore the area.

First isolated in 1998, stem cells are the body’s clay, having the potential to become any type of cell. Stem cells are divided into two classes - adult and embryonic. Adult stem cells are found among already differentiated cells of specific tissue and can usually only become one certain type of cell (blood, marrow, liver etc.) Embryonic stem cells are cultured cells obtained from the inner part of a blastocyst – a very early embryo that has divided into about 100 cells. This type of stem cells is particularly controversial because the cells must be extrancted from an embryo. However, to do this the embryo must be destroyed, a process which some believe is tantamount to taking human life.

Nonetheless, embryonic stem cells have a number of remarkable properties, properties which make them very desirable for use in medicinal research. For instance, stem cells can be grown infinitely. Unlike other permanent cell lines which are apt to mutate in later passages, embryonic stem cells remain ‘normal’ regardless of how long the cell line has been carried out. They also have the ability, under the right conditions, to give rise to all cell types of the body. Despite these advantageous properties, there is one glaring problem that remains in the usage of embryonic cells and that is the body’s immune response of rejection. The few stem cell lines that have been established are simply not a viable solution for the entire population. One way to remedy this problem would be through the establishment of a bank that contained hundreds of cell lines. This would increase the chance of a patient finding a match and thus decreasing the chance of an unfavorable immune response. However, the current administration has shown a continued unwillingness to increase our stem cell bank, a move which might...

803 words - 3 pages Inside an embryo there are dozens of stem cells. They are basically empty shells, but the special thing about them is that they are pluripotent, meaning that they can develop in to any cell or organ in human body. That makes stem cell research a gigantic part of today’s medical research. With enough research, stem cells can be a big help to the human kind. Their extraordinary abilities could help scientists return memory to Alzheimer’s patients

If any answer to the ethical debate surrounding this particular
