The Shadow Bodies of Mice: Invisible Work in Translational Medicine.

The clinician-scientist is often viewed as the crucial nexus in the translational processes that turn scientific research into medical technologies, including but not limited to pharmaceuticals. To create a point of contrast, and to consider the theme of invisible labor, this paper foregrounds an alternative actant who has also been deemed a vital nexus in translational medicine within Science and Technology Studies: the laboratory animal as model organism. Based on observational research conducted in an animal facility that was caring for laboratory mice as well as the immunological laboratory that was conducting research regarding aging and vaccine uptake using those mice, this paper explores how mouse bodies and animal technicians' knowledge of those mouse bodies are rendered invisible through the everyday flows of translation. I draw on Balka and Star's concept of "shadow bodies" to consider variations in how mouse bodies are understood across the translational process and probe the consequences this has for what knowledge is legitimately produced and by whom. By making the invisible work of mice and of technicians visible, I argue that the organizational filters of translational medicine may inadvertently make the work of animal technicians all the harder, in a manner that reproduces social inequalities.
