(Submitter supplied) 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 Descemet’s Stripping Endothelial Keratoplasty (DSEK) and Descemet’s 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. more...

(Submitter supplied) Corneal endothelium is composed of a monolayer of corneal endothelial cells (CECs) in the inner layer of cornea, which is essential for maintaining corneal transparency. In order to better characterize CECs in different developmental stages, we profiled mRNA transcriptomes in human fetal and adult corneal endothelium with the goal to identify novel molecular markers in these cells. By comparing CECs with 12 other types of tissues, we identified 245 and 284 signature genes that are highly expressed in fetal and adult CECs, respectively. more...

(Submitter supplied) Purpose: Slc4a11 KO mice show significant edema and altered corneal endothelial morphology at an early age with concomitant increased mitochondrial ROS and oxidative damage relative to wild type. Here we used RNA-Seq with the goal of finding pathways related to corneal endothelial metabolic, pump and barrier function alterations. Methods: Corneal endothelium-Descemet’s membrane (CEDM) samples were from WT and Slc4a11 KO mice at 12 weeks of age. more...

(Submitter supplied) The cornea is the clear window that lets light into the eye. It is composed of five layers: epithelium, Bowman’s layer, stroma, Descemet’s membrane and endothelium. The maintenance of its structure and transparency are determined by the functions of the different cell types populating each layer. Attempts to regenerate corneal tissue and understand disease conditions requires knowledge of how cell profiles vary across this heterogeneous tissue. more...

(Submitter supplied) The corneal endothelium is composed of a monolayer of corneal endothelial cells (CECs), which is essential for maintaining corneal transparency. Human embryonic stem cells (hESCs) hold the promise of providing an abundant donor source for generating CEC cells for cell replacement therapies. Here we demonstrate that CEC-like cells can be efficiently derived from human ESCs. In addition, we performed global gene expression profiling of stem-cell-derived CEC cells, incorporating with adult CEC cells, fetal CEC cells and other human tissue type data. more...

(Submitter supplied) Here, we evaluate the efficacy of cryopreserved human embryonic stem cell (hESC)-derived corneal endothelial cells (CECs) to form a functional monolayer of corneal endothelium (CE) in mammals (rabbits) and non-human primates (monkeys). We injected cryopreserved hESC-derived CECs in rabbits and monkeys either immediately after removing 8 mm of the central portion of the CE or a few days later when corneal edema developed. more...

(Submitter supplied) The corneas is a transparent and avascular tissue located in front of the eye. Its inner surface is lined by a monolayer of corneal endothelial cells (CECs), which maintain the cornea transparent. CECs remain arrested at a non-proliferative state and damage to these cells can compromise their function leading to corneal opacity. The primary culture of donor-derived CECs is a promising cell therapy. It confers the potential to treat multiple patients from a single donor, alleviating the global donor shortage. Nevertheless, this approach has limitations preventing its adoption, particularly culture protocols allow limited expansion of CECs and there is a lack of clear parameters to identify therapy-grade CECs. To address this limitation, a better understanding of the molecular changes arising from the primary culture of CECs is required. Using single-cell RNA sequencing on primary cultured CECs, we identify their variable transcriptomic fingerprint at the single cell level, provide a pseudo temporal reconstruction of the changes arising from primary culture, and suggest markers to assess the quality of primary CEC cultures. This research depicts a deep transcriptomic understanding of the cellular heterogeneity arising from the primary expansion of CECs and sets the basis for further improvement of culture protocols and therapies.

(Submitter supplied) To investigate the use of Plasma Rich in Growth Factors (PRGF) as the unique source of growth factors in primary cultures of human corneal endothelial cells obtained from discarded tissues. We performed gene expression profiling analysis using data obtained from RNA-seq of 8 different cell cultures. 4 of them obtained with a standard culture medium and the other 4 using a xeno free PRGF based culture medium

(Submitter supplied) Corneal organoids are useful tools for disease modeling and tissue transplantation however they have not yet been well studied during maturation. We characterized human iPSC derived corneal organoids at 1, 2, 3 and 4 months of development using single-cell RNA sequencing to determine the cellular heterogeneity at each stage. We found pluripotent cell clusters committed to epithelial cell lineage at 1 month early corneal epithelial, endothelial and stromal cells markers at 2 months, keratocytes as the largest cell population at 3 months, and a large epithelial cell population at 4 months. more...
