Stem cells could be the beginning of a whole new world, but are you for or against it? According to Wikipedia, stem cells are undifferentiated biological cells that can differentiate to become specialized cells. These cells can also divide to produce more stem cells. Scientists have found ways to use these cells to benefit others. There are several places in which these stem cells can be extracted. However, the topic is very controversial because there are two types of stem cells; adult stem cells, and embryonic stem cells. And while adult stem cells come from the initial host, embryonic stem cells come from blastocysts (an early-stage embryo), and are used for others while the embryo dies. Along with multiple benefits, there are also many risks involved with the use of stem cells, but some even believe that they could be the start of a whole new world! So are you for, or against it?
A Whole New World: For or Against?
Can you imagine a world free of disease? Well, what if I told you that the first step to such a place could be found in the study of a simple cell? Recently, a renewed interest has been taken into a specific type of cell called the stem cell. According to Wikipedia, stem cells are undifferentiated biological cells that can differentiate into specialized cells and through mitosis (division of a cell in the nucleus), and can divide to produce more stem cells. These cells can be divided into two groups; adult stem cells and embryonic stem cells. Although stem cell research may bring about a positive change to our daily lives, the topic remains very debatable since many argue that stem cells may not live up to all of their expectations.
Adult stem cells are relatively noncontroversial due to the fact that they come from the host itself, and they do not require the destruction of an embryo. They can be extracted from places like bone marrow, adipose tissue, and in the blood of adults as well as in children. Their ability to regenerate into all the different cell types, and including the organ from which they originate, has made them the focus of much therapeutic research. Adult stem cells have been used to treat a wide variety of things such as leukemia, different types of cancer, spinal cord injury, cirrhosis of the liver, chronic limb ischemia, and end-stage heart failure. However, most adult cells are limited when it comes to which type of cells they can become. This means that they are lineage-restricted stem...
