... mouse model, we have selectively labelled palatal epithelia with Dil and examined the fate of medial edge epithelial (MEE) cells during palatal fusion by localisation using a combination of conventional histology and confocal laser scanning microscopy (CLSM). In dynamic studies using CLSM, we have made...

... notochord mesoderm cell commitment Dil organiser During embryonic development, cells become committed to their fates gradually, through a hierarchy of developmental decisions until they finally differentiate - that is, they acquire the morphological and biochemical characteristics...

... rhombomere branchial arch cell migration chick Dil Strategies employed in development of the vertebrate head differ from those of the trunk in a number of important ways, foremost among which is the deployment of neural crest cells and neurogenic placodes ( Gans and Northcutt, 1983...

...Mark A. J. Selleck; Claudio D. Stern ABSTRACT Fate maps of chick Hensen’s node were generated using Dil and the lineage of individual cells studied by intracellular injection of lysine-rhodamine-dextran (LRD). The cell types contained within the node are organized both spatially and temporally...

...George N. Serbedzija; Scott Burgan; Scott E. Fraser; Marianne Bronner-Fraser ABSTRACT We have used the vital dye, Dil, to analyze the contribution of sacral neural crest cells to the enteric nervous system in chick and mouse embryos. In order to label premigratory sacral neural crest cells...

...Howard D. Pomeranz; Taube P. Rothman; Michael D. Gershon ABSTRACT Experiments were done to test the hypothesis that the avian gut is colonized by cells derived from both vagal and sacral regions of the neural crest. A fluorescent dye, dil (l,l-dioctadecyl-3,3,3′,3′-tetramethylmdocarbocya-nine...

...George N. Serbedzija; Scott E. Fraser; Marianne Bronner-Fraser Analysis of neural crest cell migration in the mouse has been difficult due to the lack of reliable cell markers. Recently, we found that injection of Dil into the chick neural tube marks premigratory neural crest cells whose endfeet...

...R. J. Colello; R. W. Guillery The carbocyanine dye, Dil, has been used to study the retinal origin of the uncrossed retinofugal component of the mouse and to show the course taken by these fibres through the optic nerve and chiasm during development. Optic axons first arrive at the chiasm...

...George N. Serbedzija; Marianne Bronner-Fraser; Scott E. Fraser ABSTRACT To permit a more detailed analysis of neural crest cell migratory pathways in the chick embryo, neural crest cells were labelled with a nondeleterious membrane intercalating vital dye, Dil. All neural tube cells with endfeet...
