Stem Cells…? … Huh? A type of cell that can turn into a variety of different types of cells in the body and do so without limit. Types of Stem Cells: Adult Stem Cells, ○ aka multipotent (limited cell types) Embryonic, ○ aka pluripotent (many cell types)
All The Facts…. About Ovaries… you ever wanted to know. A woman is born with approx 2 million eggs and never produces any more. 11,000 die each month prior to puberty After puberty, about 1,000 die per month When all eggs are gone, menopause begins. Embryos are a great source of pluripotent stem cells
Treatment Options Reprogrammable Stem Cells Stem Cells from Umbilical Cords Adult Stem Cells – from you! Somatic Cell Nuclear Transfer (SCNT): “allows scientists to produce embryonic stem cells without using sperm to fertilize an egg.” Aka “Therapeutic Cloning”
Somatic Cell Nuclear Transfer (SCNT)
Stem cells that can change into different types of cells. Involves the creation and destruction of embryos. Risk of bodily rejection. Newer technology -nuclear reprogramming “Creates stem-like cells from the patient's own cells, avoiding both these problems.”
Facial bones created from own stem cells Adult stem cells Can be used for a variety of other purposes, but are more limited.
Sources of Controversy Fertility Clinics have excess, fertile embryos thrown away. Embryos could become human beings. Stem Cell Research and Treatment can easily affect tens of millions yet research is delayed Reprogramming Stem Cells – Playing God. Biological Insurance – Storage of your own stem cells
Review and Questions? Stem Cell Technology has huge medical and ethical implications Various Methods for Stem Cell Treatments Controversy in society Future direction of stem cell research
