Extension of the somite formation period. <br /> <br /> (A) Graph plotting increasing time intervals along the x axis and increasing number of somites and the corresponding HH stage of chick development along the y axis. The red line is a theoretical line showing the progression if the speed of somitogenesis were to remain constant at 90 minutes throughout development. Each blue dot corresponds to an individual sample/embryo. The blue line is a best fit line. Dotted green line demarcates the average final number of somites. <br /> <br /> (B-G) Fix and culture analysis using the half embryo system using the caudal region of a chick embryo. Left half samples were immediately fixed whereas right half samples were cultured in vitro for different periods of time and then the expression of c-Lfng was analysed in the two halves by in situ hybridisation. (B) HH stage 20 and (C) stage 23 samples cultured for 90 minutes. <br /> <br /> (D-G) HH stage 23 samples were cultured for (D) 60 minutes, (E) 90 minutes, (F) 120 minutes and (G) 150 minutes.<br /> <br /> 1471-213X-10-24-2.jpg<br /> <br /> BMC Dev Biol. 2010; 10: 24.<br /> <br /> http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2836991/?tool=pmcentrez<br /> <br /> Published online 2010 February 25. doi: 10.1186/1471-213X-10-24.<br /> <br /> Copyright ©2010 Tenin et al; licensee BioMed Central Ltd.<br /> <br /> The chick somitogenesis oscillator is arrested before all paraxial mesoderm is segmented into somites.<br /> Tenin G, Wright D, Ferjentsik Z, Bone R, McGrew MJ, Maroto M.
