Applied Cell therapy

 


Cell therapy is the transplantation of human or animal cells to replace or repair damagedtissue.The purpose of cell therapy is to introduce cells into the body that will grow and replacedamaged tissue. Cell therapy differs from conventional stem cell therapy in that the cellsinjected into the body in cell therapy are already differentiated (e.g., muscle cells, glandcells), whereas conventional stem cell therapy utilizes undifferentiated, usually embryoniccells. Cell therapy has long been used by alternative medicine practitioners who have claimedgreat benefits; these have not been replicated by conventional medical practitioners.
Cell therapy as performed by alternative medicine practitioners is very different from thecontrolled research done by conventional stem cell medical researchers. Alternativepractitioners refer to their form of cell therapy by several other different names includingxenotransplant therapy, glandular therapy, and fresh cell therapy. The procedure involves theinjection of either whole fetal xenogenic (animal) cells (e.g., from sheep, cows, pigs, andsharks) or cell extracts from human tissue. Several different types of cells may beadministered simultaneously.
Just as Paracelsus's theory of "like cures like," the types of cells that are administeredcorrespond in some way with the organ or tissue in the patient that is failing. In other words,the cells are not species specific, but only organ specific. Alternative practitioners cannotexplain how this type of cell therapy works, but proponents claim that the injected cells travelto the similar organ from which they were taken to revitalize and stimulate that organ'sfunction and regenerate its cellular structure. Supporters of cellular treatment believe thatembryonic and fetal animal tissue contain active therapeutic agents distinct from vitamins,minerals, hormones, or enzymes. This theory and these claims are rejected by practitionersof conventional medicine.
Proponents of cell therapy claim that it has been used successfully to rebuild damagedcartilage in joints, repair spinal cord injuries, strengthen a weakened immune system, treatautoimmune diseases such as AIDS, and help patients with neurological disorders such asAlzheimer's disease, Parkinson's disease, and epilepsy. Further claims of positive resultshave been made in the treatment of a wide range of chronic conditions such asarteriosclerosis, congenital defects, and sexual dysfunction. The therapy has also been usedto treat cancer patients at a number of clinics in Tijuana, Mexico. Most of these claims areanecdotal. None of these application is supported by well-designed, controlled clinicalstudies.
