Stem Cells Different kinds of cells
Learning Objectives • stem cells are unspecialised cells found in embryos and in some adult tissues such as bone marrow • stem cells have the potential to differentiate into different types of specialised cells
At the end of the lesson you should be able to: • describe what stem cells are and their location in humans • describe how stem cells have the potential to treat sick people • If it’s highlighted in RED you need to know it – so write it down!
Most adult cells in the body have a particular purpose which cannot be changed – They are specialised. • Stem Cells are different: • They are still at an early stage of development and retain the potential to become many different types of cell.
Two types of Stem Cell • Embryonic Stem Cells • Easy to grow large numbers in culture • They have the ability to become virtually any type of cell in the body • Adult Stem Cells • Found in organs • Maintain the organ by repairing any damage • Their potential to become different types of cell is more limited
Stem Cell “Repair Kit” • Scientists are researching ways Stem Cells can be used as a kind of “super repair kit” • Some of the conditions that may eventually be treated using Stem Cell Therapy include: • Parkinson’s Disease, Alzheimer’s Disease, Heart Disease, Stroke, Arthritis, Diabetes, Burns, and Spinal Cord Damage.
