  Hey lilpanda,
  My work is all with embryonic stem cells, which were originally taken from embryos more than 10 years ago and have been kept alive in a lab since!

  Hi lilpanda, I get lots of stem cells from the bone marrow. Here all of your blood cells are made including your red blood cells and all of your white blood cells, which make up your immune system

  Hi lilpanda
  
  I work with stem cells from wisdom teeth and also from bone marrow. There aren’t many stem cells in teeth so we have to grow them in the lab to get more cells. I also want to start working with stem cells from fat and the umbilical cord, if we can get funding.
