Figure 3. Telomerase activity from the embryo stage to senescence in the medaka. (A) Representative TRAP assay for the embryo stage and the whole body of the adult. RTA values (Related Telomerase Activity; the activity relative to that in SiHa cells as a positive control) are listed at the bottom. (B) Scatter plots of telomerase dynamics and the fitted regression model. G (dark gray shading), growth stage; Ado (clear), adolescent stage; Adu (light gray shading), adult stage.
