hCD68-GFP transgenic mouse
A new tool to study monocyte and macrophage biology
Using funding from the British Heart Foundation the hCD68-GPF mouse was developed to facilitate the study of macrophage biology in the wider scientific community. We have made this line freely available via The Jackson Lab.
The hCD68-GFP mouse allows both study of monocyte trafficking and longer term monocyte to macrophage differentiation studies. In contrast to other widely used strains, such as the CX3CR1GFP line, monocytes retain GFP expression after differentiation to mature tissue macrophages.
- Expression during embryonic development is visible prior to E12.5.
- Expression in blood, bone marrow and splenic monocytes of both inflammatory (Ly-6CHI ) and patrolling (Ly-6CLO) subsets.
- GFP expression is maintained and enhanced in differentiated macrophages, allowing clear discrimination above cellular autofluoresence.
- Limited expression in other myeloid cell types, such as bone marrow neutrophils, fully characterized by reverse gating in blood, bone marrow and spleen.
