The technique of growing cells in a laboratory using an appropriate growth medium.
Cells which divide as adults:
- skin cells to repair wounds
- blood cells
- digestive cells which are worn away
Tissue engineering: growing living cells on a framework of synthetic material to produce a tissue e.g. skin tissue for deep burns.
(Other applications= blood vessel replacement, treatment of nerve diseases)
Stem cells: Undifferentiated cells capable of giving rise to different types of specialised cells. Found in adult bone marrow but the best ones are found in embryos.
Therapeutic stem cell cloning could have huge medical benefits.
