The Healthspan Machine: an automated method to screen for interventions that slow ageing.
The heterogeneity of ageing even in genetically identical C. elegans populations means studies require large numbers, particularly when interventions have small effect. The hours of labour required to achieve these numbers can become a limiting factor to the rate of information gathering. Here we present the Health-span machine, an automated nematode image capture rig which we use to gather information about changes in worm movement during aging and use this as a proxy for health. We use a single camera per plate and specific software to detect and quantify movement and decline in movement over a period of 7-10 days.
BSI Pump priming: High throughput quantitative biology of ageing
The project aim was to replicate "The Lifespan Machine" designed by Walter Fontana’s group (Harvard). This system uses high resolution flatbed scanners that have been modified to image several plates of the nematode worm, C. elegans, twice an hour across several weeks (Stroustrup et al. Nature Methods 2013: 10, p665). This system has produced excellent data, however the imaging rig is expensive to scale up and the complexity of setup could easily cause delays during a three year research project.
By reproducing the system we were able to see the current state of the art and the power of this tool to address current questions. The insight gained has become a springboard to a Biology:Physics collaboration to facilitate a high throughput quantitative biology of ageing project using of-the-shelf-imaging technology. We hope our imaging rig will facilitate the gathering usefully large datasets and will be of value to the rest of the community.
