Lago Notion Our laboratory has developed two cell and tissue models in which endothelial corneal cells from FECD specimens are expanded in vitro (two-dimensional cell model) or used to recreate an endothelium on a healthy devitalized cornea (three-dimensional tissue model) The etiology of FECD is unknown, but it seems to be a heterogenous complex inherited disorder caused by the interaction of genetic and environmental factors

Corneal endothelial cells in FECD are susceptive to oxidative stress, leading to mitochondrial dysfunction and cell death Introduction Fuchs endothelial corneal dystrophy (FECD) is the leading cause of corneal blindness in developed countries

Oxidative stress causes many forms of cell death including parthanatos, which is characterized by translocation of apoptosis-inducing factor (AIF) to. The corneal endothelium (CE) comprises a monolayer of hexagonal corneal endothelial cells (CECs) derived from neural crest cells that arise from the neuroectoderm 1 and rest on a specialized basement membrane called Descemet's membrane (DM) Our laboratory has developed two cell and tissue models in which endothelial corneal cells from FECD specimens are expanded in vitro (two-dimensional cell model) or used to recreate an endothelium on a healthy devitalized cornea (three-dimensional tissue model)
230425_a70258_02.jpg. Rare cases of early onset have been related to mutations in the COL8A2 gene (1p34.2-p32.3). In principle, there are several mechanisms by which a noncoding trinucleotide repeat (TNR) expansion in TCF4 could lead to the development of FECD, including a direct effect on TCF4 expression, production of toxic repeat-associated non-ATG (RAN) translation products and changes in RNA splicing
Pisd 20252025 Calendar Patti Andriette. The etiology of FECD is unknown, but it seems to be a heterogenous complex inherited disorder caused by the interaction of genetic and environmental factors Based on knowledge from our pilot study that TNR expansion in the CE leads to sequestration of MBNL1.
