For other cell-surface ligand-receptor pairs, we refer to Information S1. BMP indicates bone morphogenetic protein; CD, cluster of differentiation; EGF, epidermal development aspect; LDLR, low-density lipoprotein receptor; MMTV, mouse mammary tumor virus; PDGF, platelet-derived development issue; TEK, endothelial tyrosine kinase; TK, tyrosine kinase; TNF, tumor necrosis aspect; TYRO, tyrosine-protein kinase receptor; and Wnt, wingless-type integration web-site family members, member 1.a further 10 are expressed by both cardiomyocytes and fibroblasts (Table S3); just 4 are expressed PLK4 drug specifically by cardiomyocytes. If one considers not just the ligands but the comprehensive 79 ligand-receptor pairs expressed by cardiomyocytes, 31 are expressed by all 3 cell sorts and a different 36 are expressed by each cardiomyocytes and fibroblasts; just 9 are expressed especially by cardiomyocytes. What is also fascinating is the fact that most ligands expressed by all three cellJ Am Heart Assoc. 2021;ten:e019169. DOI: 10.1161/JAHA.120.Segers et alAutocrine Signaling in the HeartTable two.
