Figure Legend Snippet: ( A ) scRNA-seq of 129/Sj anterior segment tissue identifies various cell types similar to that in C57BL/6 J single-cell RNA sequencing (left panel). Expression of Egfl7 and Cdh5 in snRNA-seq endothelial cells (right panel). ( B ) Integration of B6 and 129/Sj endothelial cells followed by sub-clustering identifies BECs, LECs, IW1 SECs, IW2 SECs, OW SECs, and CCs (top panel). Integration of B6 and 129/Sj endothelial cells distributed across clusters (bottom panel). ( C ) Sub-clustering identifies complementary expression patterns of Npnt and Ccl21a in IW1 and IW2 SECs, Ackr1 in CCs, and Selp in OW SECs. ( D ) Heatmap of differentially expressed genes of the identified sub-clusters. ( E ) Violin plot showing differences in expression levels of various genes which as a combination defines individual sub-clusters. IW: Inner wall, OW: Outer wall, CC: Collector channels, BEC: Blood endothelial cell, LEC: Lymphatic endothelial cell, SEC: Schlemm’s Canal endothelial cell.
Techniques Used: RNA Sequencing Assay, Expressing
Figure Legend Snippet: ( A ) Npnt expression in a subgroup of SEC in scRNA-seq data (i) and corresponding immunofluorescence (IF) reveals high level of expression of NPNT in anterior portion of IW of SC in a frozen section (ii) and whole mount (iii and iv). ( B ) Ccl21a is expressed in SECs and LECs (i) and corresponding IF reveals high expression in posterior portion of IW of SC in a frozen section (ii) and whole mount (iii and iv). ( C ) Selp is expressed in OW SECs and CCs, a subgroup of SECs in single-cell (i) and corresponding IF (ii frozen section, iii-iv whole mount). ( D ) Ackr1 expression in a subset of CC cells (i) and corresponding IF (ii frozen section, iii whole mount). DAPI in blue labels nuclei in all panels. IW: Inner wall, OW: Outer wall, CC: Collector channels, CB: Ciliary body, LY: Lymphatic vessels, BV: Blood vessels SC: Schlemm’s canal. Ant.: Anterior SC, Post.: Posterior SC. Scale bar = 100μm.
Techniques Used: Expressing, Immunofluorescence
Figure Legend Snippet: ( A ) Immunofluorescence (IF) of NPNT shows variability in expression with a gradient of high expression in the anterior portion of SC (left panel) and uniform expression throughout IW of SC (middle panel) in flash-frozen sections. In situ hybridization using RNAscope shows the expression of Npnt in IW with an anterior expression bias (left panel) ( B ) IF of CCL21A shows variability in expression with a gradient of high expression in the posterior portion of SC (right panel) and uniform expression throughout IW of SC (left panel) in flash-frozen sections. DAPI in blue labels nuclei in all panels. ( C, D ) Gene expression analysis of endothelial cell subset in published dataset shows similar segregation of Npnt, Selp, and Ccl21a expression in SECs as seen in our dataset. CB: ciliary body, SC: Schlemm’s canal. Ant.: Anterior Schlemm’s canal, Post.: Posterior Schlemm’s canal. Scale bar = 100μm.
