Dr. Allen believes, cells injected into the body find their way to the patient's weak or damaged organ and stimulate the body's curing process. Cells do not actually travel whole, but are broken down to their molecular levels and incorporated in similar structures. This is supported by studies from the Universities of Vienna and Heidelberg, where the movement of cells labeled with dyes or radioactive material was traced after injection. Without fail, kidney cells migrated to the kidney, liver cells to the liver, and so forth.

  Dr. Allen applies cell therapy for revitalization purposes. He uses a combination of five different cell types: hypophysis (from the pituitary), liver, connective tissue, male or female gonads, and one which varies based on the needs of the patient. If the patient has problems with a certain organ, then additional cells specific to that organ can be used. Three to five injections are given in one session. For general revitalization purposes, the patient returns for further injections as necessary. This may continue for six months, one year, or even two years.

  Dr. Allen believes cell therapy stimulates the immune system, helping it either to prevent disease or to fight it when necessary. In the case of cancer, Dr. Allen feels that cell therapy enhances the overall health of cancer patients and helps them withstand the rigors of chemotherapy and radiation.

 Tom Smith, M.D., Ph.D., H.M.D., D.Hom, says, the main benefit of cell therapy is an overall stimulation of the body and its processes. He views cell therapy as an addition to other forms of therapy and feels it gives the body a basic support system that allows other therapeutic measures to work more successfully. At Dr. Smith's International Clinic for Biological Regeneration, which has branches in England and the Bahamas, patients are first screened to assess whether cell therapy is an appropriate treatment for them. Following this screening, an initial test injection is given to ensure that the patient will not suffer from an allergic reaction. For patients who exhibit a reaction, especially those with a history of allergies, cell therapy may not be advisable.

  Dr. Smith uses injections of an omnigenic (whole embryo) ultrafiltrate. Two to five injections are normally given. This preparation stimulates the connective tissues and muscles, helps to retain fluids in the tissues, and retards aging. Because this ultrafiltrate preparation contains material from all areas of the embryo, it is effective as a total body stimulant. If a patient has problems with a particular area, such as the brain, liver, or kidney, he will be given an extract of that organ as well.

  Therapeutic Immunology is a form of cell therapy in which cell extracts are administered along with antibodies raised in animals. It was developed by Dr. Stephan, who states that it has no side effects. Cells of various organs, glands, and other parts of the body are taken from specially raised animals known to be healthy and free of disease. The cells are placed in solution and filtered to remove the unwanted protein elements, and then introduced into a secondary mammal. The injected antigens react with the cells of this mammal and produce antibodies, which appear in the mammal's bloodstream and can be measured. When the antibodies reach the desired level, blood is taken in the same way as it is for vaccines. The serum is then separated and the antibodies are prepared and tested for purity and effectiveness, before being given to the patient to regenerate various parts of the immune system.

  Strict control is exercised in matching the proper cells with the antibody preparations. In order to reduce patient stress and better enable the patient to tolerate the antibody serum, the preparation is introduced by injection and suppository in low doses over a longer period of time than other forms of cell therapy. Cell extracts containing RNA (ribonucleic acid) are also used to enhance the effects.

   Bio-Nutritional therapy is an another one technique used by Dr. Stephan. In this therapy, cells, cell extracts, and antibodies are combined with nutrients and ATP (adenosine triphosphate, a compound involved in the storage and transfer of energy in cells), to promote cellular and tissue regeneration. The mixture is administered either under the tongue or via the nasal or rectal passage. This method of application helps to avoid side effects by allowing the body to absorb only as much as it needs.

  Ted Allen, M.D., of Nassau, the Bahamas, states, the therapeutic effect of cell therapy appears in three stages:

1. In some cases this response is followed by an immune reaction that can cause slight fatigue and last for several weeks. 

2. The long-term healing phase. Cellular and organ regeneration will take a minimum of four to six months, with the patient's condition continuing to improve over the next few years by way of increased stamina, better blood supply and skin tone, and an overall sense of well-being.
