ABSTRACT In this study we have tried to analyse the effect of vit.A ampule(retinol )on formation of neural tube (neurulation)in mouse (balb/c)embryo to determine the critical time of its formation and the optimum teratogenic dose of this substance in the experimental induction of neral tube defects(NTD). After we observed the vaginal plug(v.p=0day),mated animals were divided into two groups ...
fluorescent dyes Dil or DiO via microinjection to generate a fatemap of the non-neural ectoderm of Xenopus laevis embryos during neurulation. Our lineage analysis confirms that all placodes arise from a common primordium and indicates the regions of origin of the different placodes. We further use time-lapse videomicroscopy to analyse the cell movements and behaviour of ectodermal cells of deve...
