Stem cell research has bought about heated debate since the time it was reviled. Many different debates have been raised to justify and unjustified the use of stem cells for research throughout the years. The two most enduring debates that have stood the test of time have been the legal and ethical issues. The has been documented in countless research studies the advantages of the use of stem cells for research regarding the two issues stated above. There are also countless articles documenting the disadvantages regarding the stated issues. I will discuss what a stem cell is, the different types of stem cells, and the advantages and disadvantages of both types. I will also discuss the two majorly debated issues, legal and ethical, as states above.
A stem cell is fundamentally a blank cell that is capable of becoming another more differentiated cell type in the body and can be used to replace or even heal damaged tissues and cells in the body. Embryonic stem cells come from living, human embryos and can be harvested from two sources, embryos and fetuses. Embryonic stem cells are obtained by harvesting living embryos which are generally 5-7 days old. The removal of embryonic stem cells invariably results in the destruction of the embryo. Fetuses are another type of stem cell called an embryonic germ cell can be obtained from either miscarriages or aborted fetuses. Advantages of embryonic stem cells are that they appear to have the potential to make any cell, one embryonic cell line can potentially provide an endless supply of cells with define characteristics, and they are readily available due to in vitro fertilization clinics. Some disadvantages of embryonic stem cells is that they are difficult to differentiate uniformly and homogeneously into target tissue, embryonic stem cells from random donors are likely to
