Stem Cells have the potential to make a large positive impact in the medical field. It is important to know the basics of Stem Cells, the difference between the types of Stem Cells, and the possible uses of Stem Cells. Knowing the basics of stem cells is a necessity to understanding how they might positively impact those with a medical condition. Stem cell research is still moderately new and has come a long way over the past 50 years. The idea of their existence was put forward in 1908 by Russian histologist named Alexander Maksimov. Maksimov named and hypothesized the presence of stem cells. It was not until 1963 that Canadian Scientists, James E. Till and Ernest A. McCulloch actually demonstrated the existence of self-renewing cells found in the bone marrow of mice, this began the exploration into what might be the most positive impact the medical field will ever see.

In the first five days the inner cells of the organism will create the entire body, including all of cell types and organs such as the heart, lung, skin, sperm, eggs and other tissues. This is where stem cells come into play to form and take on specialized functions in the body. Stem Cells are defined as unspecialized cells that retain the ability to divide throughout life and take the place of specialized cells that get damaged or that die. Millions of people are faced with many medical conditions such as birth defects and cancers every year. The number of new medical conditions continues to grow as well every year. A lot of that is due to abnormal cell division and differentiation. The human body has over 200 different types of cells throughout it and a stem cell has the potential to replace just about all of them. They can initially duplicate or transform themselves into a different tissue type and function depending on what cells they are surrounded with such as nerve or skin cells. These cells are thought to divide indeterminately. Stem cells act as an...
