OxTalks will soon move to the new Halo platform and will become 'Oxford Events.' There will be a need for an OxTalks freeze. This was previously planned for Friday 14th November – a new date will be shared as soon as it is available (full details will be available on the Staff Gateway).
In the meantime, the OxTalks site will remain active and events will continue to be published.
If staff have any questions about the Oxford Events launch, please contact halo@digital.ox.ac.uk
Using mouse spermatogenesis as a model, we present evidence that stem cell density regulation relies on a feedback mechanism, reminiscent of “quorum sensing” in bacterial populations, in which cells transition reversibly between states biased for renewal and primed for differentiation. Using a modelling-based approach, we show that this mechanism provides predictive insights into stem cell dynamics during steady-state, as well as under perturbed and transplantation conditions. We discuss the potential implications of these findings for the regulation of stem cell density in other epithelial contexts.
