Review: on Stem Cell ResearchAuthor(s): Hellen Marker*
Stem cells are specialized cells that have the potential to develop into many different types of cells in the body. They are often referred to as the building blocks of life as they are involved in the growth, repair, and regeneration of tissues and organs in the body. Stem cells are unique in their ability to self-renew, meaning they can divide and produce more stem cells, as well as differentiate into specialized cells such as blood cells, bone cells, or nerve cells. There are two main types of stem cells: embryonic stem cells and adult stem cells. Embryonic stem cells are derived from the inner cell mass of a developing embryo and are pluripotent, meaning they can differentiate into any type of cell in the body. Adult stem cells, on the other hand, are found in various tissues and organs throughout the body and are multipotent, meaning they can differentiate into a limited number of specialized cells.
