Human Genetics • The study of inheritance as it occurs in human beings • Stem cell research • Clinical genetics • Molecular genetics
Stem Cell Research • Stem Cell • An undifferentiated cell found among differentiated cells • Can differentiate to be specialized cell type
Adult Stem Cell • Primary Role • Maintain & repair the tissue where found • Research began 50 years ago • Generate bone, cartilage, fat, cells blood formation, connective tissue
Embryonic Stem Cells • Stem cells derived from Embryos • From in vitro fertilization • Donated for research with informed consent
Embryonic Stem Cells • Cell must be grown carefully to remain undifferentiated • Cannot for embryoid bodies • Use “recipes” to create specific differentiation
Embryonic Stem Cells as Treatment • Parkinson’s disease • Diabetes • Traumatic spinal cord injury • Muscular dystrophy • Heart disease • Vision • Hearing loss
Goal of Stem Cell Research • ID how undifferentiated stem cells become the differentiated cells that form tissues and organs • http://www.youtube.com/watch?v=yvCwPdl1Q78
Current Stem Cell use • Hematopoietic Stem Cells • Tx – leukemia, lymphoma, blood disorders • Limited use to Tx • Diabetes, kidney cancer, liver disease, coronary disease, autoimmune, inflammatory disease
Stem Cell Controversy • When does life begin? • Embryonic stem cell research involved creation & destruction of human embryo
Understanding Stem Cell Blastocyst 8 weeks after fertilization • 4-5 days post fertilization • 50-150 cells
When Human Embryo is destroyed • Inner Cell Mass is isolated to prevent cell differentiation
Genetic Markers • Genetic Marker ID • Report of potential health risks • Controversy • Determine insurance qualification & premiums • Genetic marker breast cancer- request a prophylactic mastectomy
GINA Act of 2008 • May of 2008 President Bush signed into Law • Genetic Information Nondiscrimination Act • Prohibits discrimination on the basis of genetic information • Prohibits employers from using genetic info when employing
Benefits of Genetic Marker ID • http://www.youtube.com/watch?v=q8WDjrmhtF0
