This cell line was derived from a preimplantation genetic diagnosis (PGD) embryo carrying mutations associated with cystic fibrosis. Karyotype: 46,XX.
Derivation and culture medium (hES medium): Knockout Dulbecco’s modified Eagle’s medium (KO DMEM) supplemented with Knockout-Serum Replacement (KO-SR; 20%), L-glutamine (2 mmol/l), non-essential amino acids (1%), beta-mercaptoethanol (0.1 mmol/l) and human recombinant basic fibroblast growth factor (hrbFGF; 4 ng/ml). CF1 MEF cells are used as feeder cells.
