SUMMARY:Wave Phenomena during Embryonic Patterning - David Jörg
DTSTART:20151029T120000Z
DTEND:20151029T130000Z
UID:TALK61634@talks.cam.ac.uk
CONTACT:Salvatore Tesoro
DESCRIPTION:In all vertebrate animals\, including humans\, the segmentatio
 n of the body plan proceeds during embryonic development: the elongating b
 ody axis segments rhythmically and sequentially into somites\, the precurs
 ors of vertebrae and ribs. Segmentation is controlled by a pattern forming
  system based on coupled cellular oscillations in gene product concentrati
 ons. Coordinated oscillations across the segmenting tissue generate waves 
 that travel across the segmenting tissue and guide the segmentation proces
 s. In this talk\, I will present results from a combined theoretical and e
 xperimental approach\, showing that the period of segmentation results fro
 m the collective behavior of many oscillating cells and is affected by phe
 nomena known from wave physics such as a Doppler effect and a dynamic chan
 ge of the wavelength.
