  • Slide 4
  • Stem cells are pluripotent. Stem cells serve as a repair system for the body. Stem cells have the potential in many different areas of health and medical research. By studying stem cells we can understand diseases and how serious conditions occur. Stem cells may be used one day in the future to make cells and tissues for therapy for many different diseases. Stem Cells
  • Slide 5
  • Classification Formed as a normal part of embryonic development Can be isolated from an early embryo and grown in a dish
  • Slide 6
  • Also called adult stem cells Exist naturally in body Important for growth, healing, and replacing cells lost through daily wear and tear Can become only a subset of related cell types Classification
  • Slide 7
  • Stem cell therapies are not new Somatic Cell Therapy for blood and skin diseases Stem cell therapies are not new Somatic Cell Therapy for blood and skin diseases Current Uses Regenerative capabilities of human skin to treat victims of severe burns using skin transplants Possible cause stem cells located under top layer of skin that reproduce worn out skin cells daily After severe burns, source of these reproducing stem cells are destroyed Past: used to treat burns by transplanting sections of skin of undamaged area to burned areas but if not enough unharmed skin found then no treatment Now: scientists grow sheets of new skin by culturing stem cells from small pieces of healthy skin
  • Slide 8
  • Current Uses Can already treat leukemia, sickle cell anemia, bone marrow damage, some metabolic disorders and immunodeficiencies where the body has lost ability to replenish its healthy blood cells Hematopoietic stem cell gives rise to all blood cells Only way to use hematopoietic stem cells is bone marrow transplants Scientists are exploring new use for these stem cells that go beyond blood related diseases
  • Slide 9
  • Canada: Governed by Assisted Humans Reproduction Act Protect principles of free and informed consent, human dignity, non- commercialization of gametes and embryos and respect for embryos Not ethically acceptable to create human embryos for research In vitro fertilization embryos may be used Reproductive and research cloning are prohibited and punishable Legalities
  • Slide 10
  • Slide 11
  • Classification Created artificially by reprogramming patients cells Made from readily available somatic cells An alternate to hES but not the same
  • Slide 12
  • Classification Method of cloning patient-specific embryonic stem cells Also known as nuclear transfer
  • Slide 13
  • Potential Uses There are many potential uses and applications of Stem Cells. The three I am going to discuss are: Resource for Testing New Medical Treatments Development and Disease Research Regenerative Medicine
  • Slide 14
  • Potential Uses
  • Slide 15
  • Antipsychotic drug, Thioridazine, found by McMaster University researchers, is a smart drug that kills only cancer stem cells and appears to have no effect on normal cells Was removed from shelved by Health Canada because it causes irregular heartbeat that may cause sudden death One of 26 drugs found by Bhatia and his team Studying how Thioridazine works also led McMaster researchers to discover new ways in which cancer stem cells grow and evolve. New Research
  • Slide 16
  • As we grow from fertilized eggs into fully formed human beings, stem cells give rise to all of our differentiated tissues and organs. Stem cells continue to play an important role throughout our lives as they help to heal and maintain our bodies. Stem cells offer an exciting promise for future therapies and may be used one day to make cells and tissues for therapy for many devastating diseases like Parkinson's, Alzheimer's and Diabetes. Conclusion
