Basic Information

Common Name
B-hCD47 MC38
Catalog Number
Cell Type/Disease
Colon Carcinoma
Mus musculus, C57BL/6

Target strategy

The exogenous promoter and human CD47 coding sequence was inserted to replace part of murine exon 2 and all of exon 3. The insertion disrupts the endogenous murine Cd47 gene, resulting in a non-functional transcript.

Protein expression analysis

CD47 expression analysis in B-hCD47 MC38 cells by flow cytometry. Single cell suspensions from wild-type MC38 and B-hCD47 MC38 cultures were stained with species-specific anti-CD47 antibody. Human CD47 was detected on the surface of B-hCD47 MC38 cells but not wild-type MC38 cells. The 1-B3 clone of B-hCD47 MC38 cells was used for in vivo experiments.

Tumor growth curve

Subcutaneous homograft tumor growth of B-hCD47 MC38 cells. B-hCD47 MC38 cells (1×106) were subcutaneously implanted into B-hSIRPA/hCD47 mice (female, 7-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-hCD47 MC38 cells were able to establish tumors in vivo and can be used for efficacy studies.
