7.2 Pluripotent Stem Cells

Steps of cloning

Induction, cloning, fertilisation, parthenogenesis

Advantage of embryonic stem cells

Can grow indefinitely, easier to obtain

Disadvantage of embryonic stem cells

Involves destruction of embryos, can give rise to many different structures

Reproductive cloning

To produce genetically identical individuals

Therapeutic cloning

Creating a cloned embryo to produce embryonic stem cells with same dna as donor cell

How does therapeutic cloning work?

nucleus transferred into an enucleated egg, cultured into an early embryo, differentiated into desired cell type, transplanted back into the patient
