The Genea050 human embryonic stem cell line was derived from a donated, fully commercially consented ART blastocyst, carrying a deletion in 4q35 with only 5 D4Z4 repeats by PGD linkage analysis, indicative of FSHD1. Following ICM outgrowth on inactivated human feeders, karyotype was confirmed as 46, XY and STR analysis demonstrated a male Allele pattern. The hESC line had pluripotent cell morphology, 92% of cells expressed Nanog, 97% Oct4, 79% Tra1-60 and 99% SSEA4, gave a Pluritest Pluripotency score of 25.45, Novelty of 1.45 demonstrated Alkaline Phosphatase activity and tri-lineage teratoma formation. The cell line was negative for Mycoplasma and visible contamination.
