FAP and neoplasm: For the subcutaneous xenograft model (Fig. 8b), the weight of tumors in anti-NC-BGN HGC27 group were noticeably heavier than those in anti-BGN HGC27 group, anti-BGN HGC27+CAFLCs/sh-control group, anti-BGN HGC27+CAFLCs/sh-FAP group, further analysis showed the weight of tumors in anti-BGN HGC27+CAFLCs/sh-control group were obviously heavier than those in anti-BGN HGC27 group, anti-BGN HGC27+CAFLCs/sh-FAP group, while two groups of anti-BGN HGC27, anti-BGN HGC27+CAFLCs/sh-FAP were not statistically significant in tumor weights.
