Generation of Two Induced Pluripotent Stem Cell Lines from Blood Cells of a Prostate Cancer Patient Carrying Germline Mutation in CHEK2

The authors generated two iPSC lines ZNHi001-A and ZNHi001-B from a prostate cancer patient carrying germline mutation in CHEK2 which might increase the risk of prostate cancer. Pluripotency and multi-lineage differentiation capacity of the two iPSC lines were confirmed by gene expression and teratoma assay.
