Biomedical Scientists are not confined to NHS laboratories. Biomedical Scientists along with scientists in other inter-related medical disciplines seek out to understand human anatomy, genetics, immunology, physiology and behaviour at all levels. This is sometimes achieved through the use of model systems that are homologous to various aspects of human biology. The research that is carried out either in Universities or Pharmaceutical companies by Biomedical Scientists has led to the development of new treatments for a wide range of degenerative and genetic disorders. Stem cell biology, cloning, genetic screening/therapies and other areas of biomedical science have all been generated by the work of Biomedical Scientists from around the world.
