Comparative studies of oncostatin M expression in the tissues of adult rodents

Oncostatin M (OSM), a member of the interleukin-6 family of cytokines, is thought to be expressed mostly by activated T-lymphocytes and monocytes in adult animals. However, here we report specific constitutive tissue expression of OSM in the pancreas, kidney, testes, spleen, stomach, and brain, but not liver or lung, of three adult rodent species.
