HSPG2 and neoplasm: To decipher the atlas of endothelial cells of PLC, we re-clustered two EC-related supra-clusters (13,030 cells), and obtained 15 sub-clusters, including CLEC4G+ liver sinusoidal ECs (LSECs: C1, C2, C3, C9, and C13), tumor-associated ECs (TAECs: C4, C7, and C10), intermediate-state ECs (C5 and C8), and other ECs (Fig. 5a).
