Collagen-producing eye cell atlas reveals distinct fibroblast fates in early injury versus fibrotic subretinal disease
Listed in NCBI GEO
Fibrosis is the end-stage of a maladaptive process that occurs when the body's normal wound-healing strategy becomes dysregulated.
Description
Subretinal fibrosis is the end stage of neovascular age-related macular degeneration (nAMD), the most common cause of central vision loss in people over the age of 50. The cellular sources of excess extracellular matrix contributing to subretinal fibrosis are unknown, as is the heterogeneity of cells involved in the fibrotic process.
Here we identify cells contributing to subretinal fibrosis by using Col1a1-YFP reporter mice to non-invasively image collagen production in real-time in vivo in two disease models, 1) a resolving retinal injury model and 2) a fibrotic model of subretinal disease. We create a collagen-producing eye cell atlas for subretinal injury and demonstrate subretinal fibroblast heterogeneity in healthy, resolving and fibrotic tissue.

We identify distinct molecular characteristics of general repair/resolving fibroblast populations versus pathogenic pro-fibrotic collagen-producing fibroblasts. Integration of this collagen-producing eye cell atlas with a published collagen-producing lung cell atlas shows conserved pro-fibrotic fibroblasts in both organs, yet also uncovers novel tissue-specific fibroblast populations unique to subretinal fibrosis. A Fap+Fgl2+ fibroblast population significantly expands in subretinal fibrosis that expresses the highest levels of collagens and distinctively expresses ECM components periostin, col15a1 and col6a5.
Immunolabelling of mouse and human-donor eye tissue support the fibroblastic expression and peri-vascular location of periostin as clearly distinguishing between bona-fide fibrosis and early disease in nAMD. Our collagen-producing eye cell atlas is a valuable resource for studying distinct fibroblast subsets in homeostasis, early injury and fibrosis
