Stem cells are specialized cells that are found in multicellular organisms. The have the unique capability of being able to divide and differentiate into a variety of different kinds of specialized cells. This unique ability allows stem cells to play many roles, one being to contribute as an internal repair system. The ability to divide without limit allows them to help replenish certain cells types and tissues. Since the 1980’s when stem cells were first isolated, scientists have been working to understand their behavior and properties in hopes of altering care of individuals with hematologic, oncologic, dermatologic, ophthalmologic, and orthopedic conditions. In recent years, there has been a tremendous increase in our understanding of stem cell biology. Recent studies have shown that adult stem cells can be isolated from a wide variety of tissues, including bone marrow, peripheral blood, muscle, and adipose tissue. The potential clinical applications lead to an extended interest in the use of stem cells in many medical disciplines. The most important role stem cells play in medicine is stem cell therapy: this is when cells that have been lost, destroyed, or altered are replaced. Advances in stem cell research have occurred sporadically since their discovery, however, positive outcomes and benefits are becoming more common with our improved understanding go their properties. Serious ethical concerns have been raised regarding stem cell research. Such concerns for example include and are not limited to issues about disruption of embryos to recover usable stem cell lines. This project reviewed the timeline of development for stem cell research with in depth detail of the significant milestones reached in the development of this important area of biological research.
