Derivation of human embryonic stem cell lines from embryos obtained after IVF and after PGD for monogenic disorders.
BACKGROUND Human embryonic stem (hES) cells are pluripotent cells usually derived from the inner cell mass (ICM) of blastocysts. Because of their ability to differentiate into all three embryonicExpand
