Stem cells are found in the early embryo, the foetus, amniotic fluid, the placenta and umbilical cord blood.
After birth and for the rest of life, stem cells continue to reside in many sites of the body, including skin, hair follicles, bone marrow and blood, brain and spinal cord, the lining of the nose, gut, lung, joint fluid, muscle, fat, and menstrual blood, to name a few.
In the growing body, stem cells are responsible for generating new tissues, and once growth is complete, stem cells are responsible for repair and healing of injuries, and regeneration of damaged and ageing tissues.
The interest in these cells originated from their ability to divide indefinitely and generate various many cell types from a few stem cells. Early scientists recognised that organ regeneration could be possible from these special type of cells.
Stem Cell Therapy is an advanced process which introduces these self-regenerating stem cells into damaged joints. Long-term studies around the world including Australia are ongoing to determine the effects of such treatment on cartilage repair.
