Project description:Purpose: We previously reported the generation of corneal endothelial cells (CECs) using the human peripheral blood mononuclear cells (PBMC)-originated induced pluripotent stem cells (iPSCs). Herein, we extend our analysis through RNA-Seq based transcriptome profiling of H9 human embryonic stem cells (hESCs)- and iPSCs-derived CECs. Methods: The PBMC obtained from a healthy donor were subjected to generate iPSCs using Sendai-virus delivery system Cytotune 2.0 whereas the H9 hESCs were obtained commercially. Both hESCs and iPSCs were subjected to the 20-day procedure according to our previously published CECs generation method. The differentiated CECs were characterized by immunocytochemistry. Total RNA from hESCs- and iPSCs-derived CECs was used for the preparation of RNA-Seq libraries, which were sequenced on HiSeq 2500 system. The raw RNA-Seq reads were processed and analyzed using Lasergene Genomics Suite and the expression profiles were examined for differential expression using Spotfire DecisionSite with Functional Genomics. Results: The hESCs and iPSCs were differentiated into CECs through multipotent neural crest cells (NCCs) using a 20-day procedure. The differentiating CECs on day 20 (D20) exhibited a tightly packed hexagonal/polygonal shape, which expressed CECs-associated markers, zona occludens-1 and N-cadherin at the cell boundaries. A total of 180.18, and 179.01 million reads were obtained for hESCs- and iPSCs-derived CECs, respectively. Of these, >97% reads aligned to the human reference genome resulting in >250x sequence coverage for both hESCs- and iPSCs-derived CECs. Additional analysis identified expression (≥ 0.659 RPKM) of 13,561 and 13,551 genes in hESCs- and iPSCs-derived CECs, respectively, representing ~68% of the total human protein-coding transcriptome expressed in these CECs. Finally, a comparative analysis of both hESCs- and iPSCs-derived CECs transcriptomes identified >95% similarity at the gene level. Conclusion: These analyses reveal an overall similar transcriptional profile in both hESCs- and iPSCs-derived CECs.

Project description:Corneal endothelial cells (CECs) are critical to maintaining clarity of the cornea. This study was initiated to develop peripheral blood mononuclear cells (PBMC)-originated induced pluripotent stem cells (iPSCs)-derived CECs. We isolated PBMC and programmed the mononuclear cells to generate iPSCs. Subsequently, the PBMC-originated iPSCs were differentiated to CECs. The morphology of differentiating iPSCs was examined at regular intervals by phase contrast microscopy. In parallel, the expression of pluripotent, and CECs-associated markers was investigated by quantitative real-time PCR (qRT-PCR). The molecular architecture of the iPSCs-derived CECs and human corneal endothelium (CE) were examined by mass spectrometry-based proteome sequencing. The PBMC-originated iPSCs expressed pluripotent-specific markers at levels similar to expression in H9 human embryonic stem cells (hESCs). Phase contrast microscopy illustrated that iPSCs-derived CECs are tightly adherent, exhibiting a hexagonal-like shape, one of the cardinal characteristics of CECs. The CECs-associated markers were expressed at many orders of magnitude higher in iPSCs-derived CECs at days 13, 20, and 30 compared to their respective levels in iPSCs. Importantly, only residual expression levels of pluripotency markers were detected in iPSCs-derived CECs. Mass spectrometry-based proteome profiling identified 10,575 proteins in iPSCs-derived CECs. In parallel, we completed proteome profiling of the human CE identifying 6345 proteins. Of these, 5763 proteins were identified in the iPSCs-derived CECs suggesting a 90.82% overlap between the iPSCs-derived CECs and human CE proteomes. Importantly, cryopreservation of iPSCs-derived CECs did not affect the tight adherence of CECs, and their hexagonal-like shape while expressing high levels of CECs-associated markers. We have successfully developed a personalized approach to generate CECs that closely mimic the molecular architecture of the human CE. To the best of our knowledge, this is the first report describing the development of PBMC-originated, iPSCs-derived CECs.

Project description:Purpose: To investigate the transcriptomes of H9 human embryonic stem cells (hESCs)- and peripheral blood mononuclear cells (PBMC) originated induced pluripotent stem cells (iPSCs)-derived early stage lentoid bodies at day 24 through RNA-Seq based whole transcriptome sequencing. Methods: The PBMC obtained from a healthy donor were subjected to generate iPSCs using Sendai-virus delivery system Cytotune 2.0 whereas the H9 hESCs were obtained commercially. Both hESCs and iPSCs were differentiated into lentoid bodies using “fried egg” method with feeder-free conditions as described previously. The differentiating lentoid bodies were examined for the expression of lens-specific and pluripotency markers at days 0, 6, 10, 15 and 24 by quantitative real-time PCR (qRT-PCR). Briefly, four biological replicates for each hESCs- and iPSC-derived lentoid bodies at day 24 were used for the RNA-Seq library preparation followed by sequencing on a single lane of HiSeq 2500. The raw reads were processed and analyzed using Lasergene Genomics Suite and the expression profiles were examined for differential expression using Spotfire DecisionSite with Functional Genomics. Results: The differentiating lentoid bodies at day 24 revealed transparent lens like morphological features with an increased expression of lens-specific markers including CRYGC. A total of 193.41, and 170.00 million reads were obtained for hESCs- and iPSCs-derived lentoid bodies, respectively. Of these, >96% reads aligned to the human reference genome resulting in >200x sequence coverage for both hESCs- and iPSCs-derived lentoid bodies. Additional analysis identified expression (≥ 0.659 RPKM) of 13,991 and 14,018 genes in hESCs- and iPSCs-derived lentoid bodies, respectively, representing ~70% of the total human protein-coding transcriptome expressed in lentoid bodies. Finally, a comparative analysis of both hESCs- and iPSCs-derived lentoid bodies transcriptomes identified >96% similarity at the gene level. Conclusion: The transcriptome analysis revealed an overall similar transcriptional profile in both hESCs- and iPSCs-derived lentoid bodies during differentiation at day 24.

Project description:Two independent protocols for deriving HLCs from hESCs and iPSCs were adopted and further characterization included immunocytochemistry, real-time RT-PCR, and in vitro functional assays. Comparative microarray-based gene expression profiling was conducted on these cells and compared to the transcriptomes of human fetal liver and adult liver progenitors. HLCs derived from hESCs and hiPSCs showed significant functional similarities, similar expression of genes important for liver physiology and common pathways. However, specific differences between the two cell types could be observed. Total RNA obtained from undifferentiated hESCs, iPSCs, HLCs (hepatocyte-like cells)-derived from hESCs and iPSCs, fetal forskin fibroblasts and fetal liver.

Project description:Human corneal endothelial cells (HCEC) form a monolayer by adhering tightly through their intercellular adhesion molecules. Located at the posterior corneal surface, they maintain corneal translucency by dehydrating the corneal stroma, mainly through the Na+- and K+-dependent ATPase (Na+/K+-ATPase). Because HCEC proliferative activity is low in vivo,we tried to activate proliferation of HCEC by inhibiting cyclin-dependent kinase inhibitors.We have here demonstrated microarray data of transduced human corneal endothelial cell lines. Affymetrix human U133 plus 2.0 array was used to transcriptionally profile to compare cultured human corneal endothelial cells and transduced human corneal endothelial cells.

Project description:This dataset contains proteomic profiles of Descemet's membrane (DM) with corneal endothelial cells derived from patients with Fuchs endothelial corneal dystrophy (FECD) and non-FECD subjects by shotgun proteomics. FECD is the most common inherited corneal disease. Fibrillar focal excrescences, called guttae, and corneal edema due to corneal endothelial cell death result in progressive vision loss. Our dataset indicated that 32 distinctive molecules were expressed only in the FECD-DM but not in the DM of the control subject, possibly having important roles in the pathophysiology of FECD.

Project description:Considerable interest has been generated for the development through cell-tissue engineering of suitable corneal endothelial graft alternatives, which can potentially alleviate the shortage of corneal transplant material. The advent of less invasive suture-less key-hole surgery options such as DescemetM-bM-^@M-^Ys Stripping Endothelial Keratoplasty (DSEK) and DescemetM-bM-^@M-^Ys Membrane Endothelial Keratoplasty (DMEK), which involve transplantation of solely the endothelial layer instead of full thickness cornea, provide further impetus for the development of alternative endothelial grafts for clinical applications. A major challenge for this endeavor is the lack of specific markers for this cell type. To identify genes that reliably mark corneal endothelial cells (CECs) in vivo and in vitro, we performed RNA-sequencing on freshly isolated human CECs (from both young and old donors), CEC cultures, and corneal stroma. Gene expression of these corneal cell types were also compared to that of other human tissue types. Based on high throughput comparative gene expression analysis, we identified a panel of markers that are: i) highly expressed in CECs from both young donors and old donors; ii) expressed in CECs in vivo and in vitro; and iii) not expressed in corneal stroma keratocytes and the activated corneal stroma fibroblasts. These were SLC4A11, COL8A2 and CYYR1. The use of this panel of genes in combination reliably ascertains the identity of the CEC cell type. A total of 20 donor corneas consisting of 10 single donor corneas and 5 paired donor corneas were used in this study. Donor age ranged from 19 - 76. This RNA-seq study included 15 pooled corneas (5 each) used form CEC old, CEC young and stroma samples.
