Human induced stem cell line derived from dermal fibroblasts. Cells have a karyotype of: normal, 46XY [90%]; abnormal, extra marker chr [10%]. Cells are pluripotency tested on 3 germ layers in EB and teratomas. The cells were reprogrammed using a retrovirus containing 3 factors: KLF4, SOX2, OCT4. [PMID: 21293464]. Cells were provided by Harvard University and maintained on KSR medium.
