33042260-4	2020	Methods and Results: By using LPA3 and LPA1 knockout mice, and neonatal SD rats treated with Ki16425 (LPA1/LPA3 inhibitor), we found that the number of proliferating cardiomyocytes, detected by coimmunostaining pH3, Ki67 or BrdU with cardiac troponin T, was significantly decreased in the LPA3 knockout mice and the Ki16425-treated rats but not in the LPA1 knockout mice during the first week of postnatal life.	3-(4-(4-((1-(2-chlorophenyl)ethoxy)carbonyl amino)-3-methyl-5-isoxazolyl) benzylsulfanyl) propanoic acid	93-100	antigen identified by monoclonal antibody Ki 67	Mus musculus	216-220
