Description

The mouse Cd36 gene was replaced by human CD36 coding sequence in B-hCD36 MC38 cells. Human CD36 is highly expressed on the surface of B-hCD36 MC38 cells.

Application

B-hCD36 MC38 cells have the capability to establish tumors in vivo and can be used for efficacy studies.

Targeting strategy

Gene targeting strategy for B-hCD36 MC38 cells. The exogenous promoter and human CD36 coding sequence was inserted to replace part of mouse Cd36. The insertion disrupts the endogenous murine Cd36 gene, resulting in a non-functional transcript.

Protein expression analysis

CD36 expression analysis in B-hCD36 MC38 cells by flow cytometry. Single cell suspensions from B-hCD36 MC38 cultures were stained with species-specific anti-CD36 antibody. Human CD36 was detected on the surface of B-hCD36 MC38 cells but not wild-type MC38 cells. The 10-G12 clone of B-hCD36 MC38 cells was used for in vivo experiments.

Tumor growth curve & Body weight changes

Subcutaneous homograft tumor growth of B-hCD36 MC38 cells. B-hCD36 MC38 cells (5x10⁵) and wild-type MC38 cells (5x10⁵) were subcutaneously implanted into B-hCD36 mice (female, 7-week-old, 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-hCD36 MC38 cells were able to establish tumors in vivo and can be used for efficacy studies.
