Generation of two Alpha-I antitrypsin deficiency patient-derived induced pluripotent stem cell lines ISRM-AATD-iPSC-1 (HHUUKDi011-A) and ISRM-AATD-iPSC-2 (HHUUKDi012-A)


SIX2-positive urine derived renal progenitor cells were isolated from a male and female alpha1-antitrypsin deficiency (AATD) patients both harboring the homozygous PiZZ genotype. The cells were reprogrammed to generate two integration-free induced pluripotent stem cell (iPSC) lines by transfecting episomal-based plasmids expressing OCT4, SOX2, NANOG, c-MYC, KLF4 and LIN28. Pluripotency was confirmed by immunocytochemistry for associated markers and embryoid body-based differentiation into the three germ layers. The iPSC lines carried the parental PiZZ genotype. Comparative transcriptome analyses with human embryonic stem cell line H9 revealed a Pearson correlation of 0.945 for ISRM-AATD-iPSC-1 and 0.939 for ISRM-AATD-iPSC-2 respectively.
