About Stem Cells

• Stem cells, also known as progenitor cells, are cells that can produce specialized cells that are used to develop or repair organs.
• There are two general types of stem cells: those of embryonic origin and those that arise from adult cells
• In adults, stem cells can be found in many tissues and organs, including the bone marrow, skin, heart, brain and immune system.
• Most therapies today are derived from adult stem cells.
