Aliases CD274;CLDN18 Disease  Colon carcinoma
Organism
Mouse 
Strain  C57BL/6

Description 

The exogenous promoter and human PD-L1 CDS was inserted into the mouse Pd-l1 exon 3, the exogenous promoter and human CLDN18.2 CDS was inserted into mouse Rosa26 locus site in B-hPD-L1 plus/hCLDN18.2 MC38. Human PD-L1 and CLDN18.2 were detected on the surface of B-hPD-L1 plus/hCLDN18.2 MC38 cells. 

Application

B-hPD-L1 plus/hCLDN18.2 MC38 cells have the capability to establish tumors in vivo and can be used for efficacy studies.

Targeting strategy

Gene targeting strategy for B-hPD-L1 plus/hCLDN18.2 MC38. The exogenous promoter and human PD-L1 CDS was inserted into the mouse Pd-l1 exon 3, the exogenous promoter and human CLDN18.2 CDS was inserted into mouse Rosa26 locus site in B-hPD-L1 plus/hCLDN18.2 MC38.

Protein expression analysis 

from clipboard

PD-L1 and CLDN18.2 expression analysis in B-hPD-L1 plus/hCLDN18.2 MC38 cells by flow cytometry. Single cell suspensions from B-hPD-L1 plus/hCLDN18.2 MC38 cultures were stained with anti-PD-L1 and anti-CLDN18.2 antibodies. Human PD-L1 and CLDN18.2 were detected on the surface of B-hPD-L1 plus/hCLDN18.2 MC38 cells. 

Tumor growth curve & Body weight changes

Subcutaneous homograft tumor growth of B-hPD-L1 plus/hCLDN18.2 MC38 cells. B-hPD-L1 plus/hCLDN18.2 MC38 cells and wild-type MC38 cells were subcutaneously implanted into C57BL/6N mice (female, 10-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-hPD-L1 plus/hCLDN18.2 MC38 cells were able to establish tumors in vivo and can be used for efficacy studies.
