Answer: Stem cells are undifferentiated cells that can divide repeatedly and can develop into different types of specialised cells and tissues.
They are found in the embryo (embryonic stem cells), and in adult bone marrow, umbilical cord blood and fat tissue (adult stem cells).
Uses:
- Treatment of blood disorders such as leukaemia and thalassemia through bone-marrow (stem cell) transplant.
- Regenerating damaged tissues, for example in heart disease, burns and spinal cord injuries.
- Possible treatment of diseases such as diabetes, Parkinson’s and Alzheimer’s disease by forming new cells.
- Growing tissues and organs in the laboratory for transplantation, and testing new medicines.
