Figure Lengend Snippet: A) NICHES analysis of AFs, mesothelial cells, pericytes, gCap, and aCap in human microvascular niche yields a quantitative cell-cell signaling atlas of AF-aCap, AF-gCap, Mesothelial-aCap, Mesothelial-gCap, Pericyte-aCap, and Pericyte-gCap visualized by low-dimensional UMAP embedding. B) FeaturePlot of top differentially expressed L/R pairs ANGPT1 - TEK , SLIT2 - ROBO4 , VEGFD - KDR , BMP5-BMPR2 , ADM - RAMP2 , WNT5A - FZD6 , PTN - RACK1 , OXT - EDNRB , and ADCYAP1 - VIPR1 from NICHES analysis C) Top 10 differentially expressed L/R pairs between different cell-cell interaction signals processed through NICHES and plotted in DoHeatmap. D) Immunostaining of representative L/R pairs from AF to microvascular endothelial cells, including SLIT2 - ROBO4 , ADM - RAMP2 , BMP5 - BMPR2 , and VEGFD - VEGFR2 in human lung section. ITGA8 is a marker for AF; PRX is a marker for microvascular endothelial cells. Scale bar 20 μm.
