The exogenous promoter and mouse Cdh17 coding sequence were inserted into the mouse genome randomly. Mouse Cdh17 is highly expressed on the surface of B-Tg(mCdh17) MC38 cells.
 

Gene targeting strategy for B-Tg(mCdh17) MC38 cells. The exogenous promoter and mouse Cdh17 coding sequence were inserted into the mouse genome randomly.

Subcutaneous homograft tumor growth of B-Tg(mCdh17) MC38 cells. B-Tg(mCdh17) MC38 cells (1x10⁶) and wild-type MC38 cells (5x10⁵) were subcutaneously implanted into C57BL/6N mice (female, 8-week-old, n=6). Tumor volume and body weight were measured twice a week. (A) Average tumor volume ± SEM. (B) Body weight (Mean ± SEM). Volume was expressed in mm³ using the formula: V=0.5 X long diameter X short diameter². As shown in panel A, B-Tg(mCdh17) MC38 cells were able to establish tumors in vivo and can be used for efficacy studies.

B-Tg(mCdh17) MC38 tumor growth of individual mice. B-Tg(mCdh17) MC38 cells (1x10⁶) and wild-type MC38 cells (5x10⁵) were subcutaneously implanted into C57BL/6N mice (female, 8-week-old, n=6). As shown in panel, B-Tg(mCdh17) MC38 cells were able to establish tumors in vivo and can be used for efficacy studies.
