FLI1 and sarcoidosis: Unlike myofibroblasts and ECM fibroblasts which enriched fibroblast activation TFs, such as GLIS1 and TRPS1, only in sarcoidosis, endothelial fibroblasts showed enrichment of FLI1, a fibroblast activation suppressor TF, and GATA2, an endothelial cell TF, strictly in sarcoidosis (Supplementary Figure S5C).
