SELP and cancer: As shown in Fig. 4a, d, coincubation with cancer cell supernatant and IgG Fab (as a control group) had no effect on CD62P expression compared to expression after supernatant treatment alone, while IV.3 Fab coincubation reduced CD62P expression significantly not only in the SiHa sup-treated group but also in EJ and SMMC.7721 sup-treated groups.
