  1. Stem Cells Alex Cart Frank Cummings

  2. Alright so what are they?1 • Stem cells are a class of undifferentiated cells that are able to differentiate into specialized cell types • Able to reproduce themselves • “Immortal” • Basically, a blank canvas orpluripotent

  5. And where do they come from?1 Embryos Adults

  6. Embryos1 • They are undifferentiated blastocysts • Four to five days old • Super controversial • The baby hasn’t begun to form yet 4

  7. Brain Bone marrow Blood Blood vessels Skeletal muscles Skin Liver Don’t divide until activated by disease or injury There is debate on what they will differentiate into Adult Stem Cells1

  8. Process • The stem cells are put in a Petri dish atop a layer of “feeder cells” or cell cultures • Depending on what the type of cell the feeder cell is, the stem cell will form into that cell

  9. Controversy1 • When does “life” start? • Are chimeras ethical? • Researchers use mouse embryos to create human stem cells • Not as controversial but still….

  11. Current Treatments6 • Helps cancer patients • Skin grafts • Like the baby we read about

  12. Brain damage Cancer Spinal cord injury Heart damage Haematopoiesis (blood cell formation) Baldness Missing teeth Deafness Blindness and vision impairment Amyotrophic lateral sclerosis Graft vs. host disease and Crohn's disease Neural and behavioral birth defects Diabetes Orthopedics Wound healing Infertility Potential Treatments
