The people behind the papers – Yasmine el Azhar and Ina Sonnen

Hes proteins are transcription factors that are dynamically expressed during embryonic development, but it remains unclear how the oscillations in Hes expression differ across cell types during development. In this new study, Ina Sonnen and colleagues find that the Notch-driven Hes1 oscillation dynamics in the mouse embryonic tail are cell-type specific. To find out more about the story behind the paper, we caught up with first author Yasmine el Azhar and corresponding author Ina Sonnen, Group Leader at the Hubrecht Institute, The Netherlands.
