History of cloning

By playerwho
  • First cloning

    First cloning

    Twinning first used on a sea urchin that was successful
  • Twinning advancement

    Twinning advancement

    Twinning first used on a vertebrate that was successful

  • Nuclear Transfer Starting up

    The same man who successfully twinned a verterbrate was also the first man to experiment with nuclear transfer
  • First Nuclear Transfer

    First Nuclear Transfer

    Two men by the names of Robert Briggs and Thomas King are the first the preform a successful nuclear transfer, on a frog.

  • Nuclear transfer from a different cell type

    a man by the name John Gurdon, managed to preform a nuclear transfer using a cell from the intestines of a frog
  • Mammalian egg cells cloned by using cell transfer

    Mammalian egg cells cloned by using cell transfer

    Mammalian egg cells are from mammals if you couldnt already tell, Derek Bromhall was the first to clone these mammal cells.

  • First Mammal created using nuclear transfer

    Using a chemical process to seperate the nucleus, Steen Willadsen was the first person to create a fully developed mammal using nuclear transfer
  • Nuclear transfer Grows

    Nuclear transfer Grows

    Cows are now added to the list of possible animals to clone.

  • Nuclear Transfer from Labratory cells

    Two sheep were created using nuclear transfer once again, but instead of using doner cells, Scientists used sheep cells from the lab.
  • First mammal created using somatic cell nuclear transfer

    First mammal created using somatic cell nuclear transfer

    Ian Wilmut and Keith Campbell created the first mammal using somatic cell nuclear transfer named dolly the sheep. this proved that every cell has the genetic DNA needed to reproduce

  • primate created by embryonic cell nuclear transfer

    Li Meng, John Ely, Richard Stouffer, and Don Wolf created a monkey using the somatic cell transfer. This showed that humans closest relative could be cloned

  • First clone using engineered cells

    Angelika Schnieke, Keith Campbell, Ian Wilmut were the first ones to create a sheep clone using genetically engineered cells
  • Period: to

    More mammals cloned using somatic cell transfer

    More and more animals are being added to the list of possible animals to clone.

  • Endangered species clones

    Scientists are cloning endangered and extinct species to help the population.

  • Primate embryonic stem cells created

    Using somatic cell nuclear transfer, primate stems cells are successfully created.
  • Human stem cells created

    Human stem cells created

    using the same methods as the primate stem cells, human stem cells are successfully cloned.
