Effects of CMPCs or Cme on conduction velocity. (A) An example of the local electrograms recorded and the corresponding activation map for each of the different cultures investigated. (B) A scatter-plot showing the effects of CMPCs and Cme CMPC on conduction velocity. Conduction velocity is calculated along lines perpendicular to the isochronal lines. Black boxes indicate electrodes excluded from analysis and black dashed lines represent isochrones lines. Cme, conditioned medium; CMPCs, cardiomyocyte progenitor cells; and NRVMs, neonatal rat ventricular myocytes. The *indicates a p < 0.001 compared to both control monolayers and monolayers cultured in Cme CMPC.
