SALL4 and gastric cancer: In response to treatment with CM collected from gastric cancer cells, we observed that HUVECs cultured in CM from si-SALL4-B cells showed a significant reduction in viable cell number, while those cultured in CM from P-SALL4-B cells showed a significantly increased number of viable cells compared to control group as measured by CCK-8 assay (Fig. 3A-D).
