A stem cell is a kind of cell produced in a four-five day old fetus, called a blastocyst, which hasn't been assigned a specific purpose in the body yet. This "unassigned" cell allows researchers to implant stem cells into dying patients to improve impaired body parts and organs. Stem cell applications, whether embryonic, adult or pluripotent, is a huge breakthrough in modern-day scientific research. For scientists, stem cells are very vital to understanding how the body works and how to improve certain body tissues and cells. As of now, the goverment is not funding adequate amounts of money to pave the way for uses for stem cells, due to ethical problems. Yet, researchers have found that stem cells can help with numerous diseases and illnesses, ranging from cancer to a "broken heart" to glaucoma.
Stem cells can be transplanted into a patient, therefore completely eliminating the problem of a non-working body organ. Stem cells can also fix chromosomal abnormalities at birth.

How are the cells injected into the body? Are they just plain injected, or are they placed with some type of tissue they are suppose to become and then are placed within the body?
