Abstract

The corneal endothelium (CE), a monolayer of hexagonal cells constitutes the innermost layer of the cornea that is critical in maintaining clarity by mediating hydration through barrier and pump functions. Corneal endothelial cells (CECs) have limited proliferative potential and therefore generation of CECs has been undertaken by many groups. We previously reported generation of CECs from peripheral blood mononuclear cell (PBMC)-originated, induced pluripotent stem cells (iPSCs). In here, we extend our analysis through next-generation seqeuncing based transcriptome profiling of H9 human embryonic stem cell (hESC)- and human PBMC-originated, iPSC-derived CECs. The differentiating CECs on day 20 (D20) exhibited a tightly packed hexagonal/polygonal shape expressing zona occludens-1 (ZO-1) and N-cadherin at the cell boundaries. Next-generation RNA sequencing of hESC- and iPSC-derived CECs detected expression (≥0.659 RPKM) of 13,546 and 13,536 genes, respectively. Comparative transcriptome analysis of hESC- and iPSC-derived CECs revealed 13,208 (>96%) genes common in both transcriptomes. Among the 13,208 genes common in these transcriptomes, 12,580 (>95%) exhibited a quantitatively similar expression. To the best of our knowledge, this is the first report presenting comparative transcriptome analysis of hESC- and iPSC-derived CECs.
