Figure 1.
Effect of 10 min treatment with PGE2 (10−6M) or sulprostone 10−6M on isolated myocyte contractility. Panel A shows traces of mean cell shortening data when cells were treated with either vehicle or PGE2 (top panel) or vehicle or sulprostone (bottom panel). Cells were paced at 3 Hz. Panel B is mean quantitative data of contraction measured as the speed of contraction (departure velocity) and the speed of relaxation (return velocity). n = 49–73 cells from 5–8 mice. Statistical significance: **p<0.01 and ***p<0.001 versus vehicle control.
