Live imaging of remyelination in the adult mouse corpus callosum

Sebastian Jessberger & Sara Bottes
Oligodendrocyte precursor cells (OPCs) retain the capacity to remyelinate axons in the corpus callosum (CC) upon demyelination. However, the dynamics of OPC activation, mode of cell division, migration, and differentiation on a single cell level remain poorly understood due to the lack of longitudinal observations of individual cells within the injured brain. After inducing focal demyelination with lysophosphatidylcholin (LPC) in the CC of adult mice, we used 2-photon microscopy to follow for up to 2...

High content genome-wide siRNA screen to investigate the coordination of cell size and RNA production

Micha Müller
Coordination of RNA abundance and transcription rates with cell size has been observed in diverse organisms and isogenic cell populations. However, how cells achieve such ‘size-scaling’ of transcription is unknown. Here we describe a genome-wide siRNA screen to find novel regulators of global RNA production in human cells. We quantify single-cell RNA production rates using metabolic pulse-labelling of RNA and subsequent high-content imaging. Our quantitative, single-cell measurements of DNA, nascent RNA, proliferating cell nuclear antigen...
