Stem Cell Informative Speech Outline
Introduction:
What are stem cells?
Stem cells are unspecialized cells with the capacity to divide and form specialized cells, when the circumstances call for it. There are two sources for stem cells: adult and embryonic. Adult stem cells are multipotent cells, which can be found in adult tissues. The cells are thought to reside in “niches” in organs and tissues, some of which are bone marrow, peripheral blood, skeletal muscle, brain, heart, and liver. These cells are capable of dividing following injury around surrounding tissue in a person.
Embryonic stem cells are taken from embryo’s that had developed from in-vitro fertilization. These embryo’s-when not needed- are donated to laboratories in the name of research.

These can be used to study how stem cells differentiate and develop into heart muscle cells, so we can get a better idea of their functioning.
2. Identify new drugs, or assess the toxic drug effects of drugs, and study diseases.
Production of different cells from stem cells:
Our stem cell of interest is the hematopoietic stem cell which was the first stem cell to be identified. They were discovered in 1960s and this paved the way for stem cell research. These are multi-potent stem cell, that can develop into the types of blood cells (red blood cells, platelets, and white blood cells). Both myeloid and lymphoid blood cells are produced from hematopoietic stem cells. Figure 1
Hematopoietic stem cells are derived from the bone marrow, and a small amount of them are also found in the umbilical cord. They are also found in the peripheral blood.
Our hematopoietic stem cells have the capability to constantly restock our demands for mature red blood cells. It was found from early experiments done on patients lethally effected by radiation, that hematopoietic stem cells had the ability to form multiple lineages of cells, while also forming daughter cells (self
