Description

The human CLDN18.2 coding sequence was inserted into the ROSA26 locus in MC38 cells. Human CLDN18.2 is highly expressed on the surface of B-hCLDN18.2 MC38 cells.

Application

B-hCLDN18.2 MC38 cells have the capability to establish tumors in vivo and can be used for efficacy studies.

Target strategy

The exogenous promoter and human CLDN18.2 coding sequence was inserted into the ROSA26 locus in murine.

Protein expression analysis

CLDN18.2 expression analysis in B-hCLDN18.2 MC38 cells by flow cytometry. Single cell suspensions from wild-type MC38 and B-hCLDN18.2 MC38 cultures were stained with species-specific anti-CLDN18.2 antibody. Human CLDN18.2 was detected on the surface of B-hCLDN18.2 MC38 cells but not wild-type MC38 cells. The 1-F6 clone of B-hCLDN18.2 MC38 cells was used for in vivo experiments.

Tumor growth curve

Subcutaneous homograft tumor growth of B-hCLDN18.2 MC38 cells. B-hCLDN18.2 MC38 cells (5×105) and wild-type MC38 cells (5×105) were subcutaneously implanted into C57BL/6 mice (female, n=5). 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-hCLDN18.2 MC38 cells were able to establish tumors in vivo and can be used for efficacy studies.
