Safety and Effectiveness of Cellular Therapy

As organ extract and cellular therapy preparations have very low antigenicity; they are not readily recognized as foreign by the recipient's immune system. Niehans' proven theory states that foetal cells circulate from the site of injection until they recognize and congregate at the human counterpart organ (liver cells go to the liver, reproductive organ cells go to the reproductive organs, heart cells go the heart, etc.). These young cells, which are functionally organ specific but not species specific, imprint their vigour upon old, tired, and degenerating cells, stimulating them to function with renewed efficiency. The organ itself then retains its vigour and vitality.
