The Swiss doctor Prof. Niehans first injected cells originating from animal organs as early as 1931. He practiced this method in the years that followed until his death in 1971. My grandfather Dr. Philipp Janson was one of the first German doctors to be introduced to this method by Prof. Niehans in 1948/49. My father Dr. Wolfgang Janson-Müller took over the practice in 1968 and has perfected this method in the course of the next 35 years. I have been applying this therapy in accordance with the Niehans method since 1998, carrying the tradition into the third generation.

This involves immediate processing of the required organs after harvesting the live cells from the donor animal without any measure of preservation and subsequent intramuscular injection into the patient. The preparation used in cell therapy is a suspension of many hundreds of thousands of cells and tiny cell groups. Each cell is a small organism in itself with its own life and metabolism. In being the smallest living unit, the cell is the carrier of life. All human and animal organ cells are formed in accordance with a uniform basic scheme and possess the same structures and basic physiological functions. Cell therapy uses organs taken from foetal or juvenile animals. Fetal cells are preferred to cells from adult animals because they are easier to obtain sterile and their minimal allergizing characteristics make them more compatible for recipients. The fetus, unborn in the womb, does not dispose over any immune activity itself.
