OxTalks Change Freeze Starts 2 March
Oxford Events, the new replacement for OxTalks, will launch on 16th March. The two-week OxTalks freeze period starts on Monday 2nd March. During this time, there will be no facility to publish or edit events. The existing OxTalks site will remain available to view during this period. Once Oxford Events launches, you will need a Halo login to submit events. Full details are available on the Staff Gateway.
Developmental Control of Avian Skin Patterning
This seminar will be held online via Zoom. Please see the booking URL for joining information.
During pattern formation, morphogenetic events provide a response of the naïve tissue to chemical and mechanical positional cues. To what extent these processes shape pattern establishment and contribute to natural variation remains unclear. Marie and colleagues studied cell dynamics occurring during the emergence of feather array geometries in birds, which involves a gradual regionalisation of the skin through self-organisation. They identified highly dynamic modifications of local cell density, movement, and shape occurring during primordia emergence in the Japanese quail. Using inter-species comparison in poultry, finch, emu, ostrich and penguin embryos, followed by perturbation of skin architecture ex vivo, they showed that oriented anisotropy of dermal cells prior to primordia formation is necessary for the regularity of the final array. The results provide key insights into the cellular basis of self-organisation and demonstrate that initial tissue morphology constrains pattern attributes, uncovering a morphogenetic mechanism contributing to pattern evolution.
