  • Red Blood Cells (RBC)
    Transports oxygen in hemoglobin Disk Shape holds more oxygen
  • Muscle cell differentiation Lo
    Long flat cells in bundles to help with muscle contraction. Has more mitochondria
  • Sperm cell differentiation
    Male reproductive unit. Has flagella to help it swim and more mitochondria for energy to swim
  • stem cell research
    technology that takes primitive human cells and develops them into most any of the 220 varieties of cells in the human body
  • Outcomes of stem cell research
    Grow new organs Replaced damaged tissues cure disease study sick cells
  • Egg Cell differentiation
    Female reproductive unit. Large cell with nucleus for growing fetus. Lots of cytoplasm with stored nutrients
  • Nerve cell differentiation
    Send messages through electrical impulses Cell is long and branched out - increased surface area to receive and send messages
  • How is stem cells function determined?
    Determined by which genes are activated in DNA
  • Stem cell research ethical issues
    Religious "Playing God" Destruction of Life
  • stem cells
    unspecialized cells that retain the ability to become a wide variety of specialized cells
  • Induced adult stem cells (Induced Pluripotent Stem Cells - IPSC)
    Adult cell that can manipulated in the lab to be able to grow any type of cell
  • adult stem cells
    stem cells that are found in adults that can differentiate and form a limited number of cells
  • embryonic stem cells
    An undifferentiated cell, taken from an embryo that has potential to give rise to various other cell or tissue types
  • Undifferentiated cells
    Cells that have not specialized in any particular function
