From each microspot, two bright-field images (during labeling) and three 3-colour fluorescence images (after removing the label) were taken using an EVOS-FL microscope (Life Technologies, Bleiswijk, the Netherlands) equipped with Cy5, RFP, and GFP LEDs; an Olympus UPLSAPO 60× oil immersion objective; and a sensitive 1360 × 1024 pixel CCD camera [49 (link)]. A standardized image analysis was performed using semiautomated scripts operated in Fiji (ImageJ), as described before [49 (link)]. Parameters extracted from bright-field images (P1–5), including thrombus signature scores (P3–5), and parameters from fluorescence images (P6–8) are specified in Table 1.
