Derivation of Trisomy 21 affected human embryonic stem cell line Genea053.

The Genea053 human embryonic stem cell line was derived from a donated, fully commercially consented ART blastocyst, carrying Trisomy 21, indicative of Down Syndrome. Following ICM outgrowth on inactivated human feeders, CGH and STR analysis demonstrated a 47, XY, +21 karyotype and male allele pattern. The hESC line had pluripotent cell morphology and expressed pluripotent cell markers including 83% Nanog positive, 87% Oct4, 88% Tra1-60 and 98% SSEA4. The cell line was negative for Mycoplasma and visible contamination.
