Outline of Final Research Achievements |
We successfully generated multiple iPS cell lines from MDS clones (MDS-iPSC lines) of several MDS patients with abnormal karyotypes. We assessed hematopoietic differentiation potential of MDS-iPSC lines and isogenic normal T-iPSC lines. Hematopoietic colony formation in methylcellulose culture and further differentiation in erythroid and neutrophil culture were severely impaired in all tested MDS-iPSC lines. Next, we performed microarray analysis in hematopoietic progenitor cells re-induced from MDS-iPSC lines and isogenic normal iPSC lines, identifying MDS-specific expression changes. Finally, we performed whole-exome analysis to find that some of the somatic mutations detected in bulk cells of this MDS patient are shared in MDS-iPSC lines but not in isogenic normal iPSC lines.
