“The expression of the cannabinoid receptor type 2 (CB2R) was investigated by immunohistochemistry, Western blotting, and RT-PCR during wound healing of contused skeletal muscle in rats with attempt of its applicability to skeletal muscle wound age estimation…

In conclusion, dynamic distribution and expression of CB2R suggest that CB2R be involved in modulating macrophages in response to inflammatory event in rat skeletal muscle wound healing and CB2R be available as a marker for wound age determination.”
