..., which also lacks epithelial-to-mesenchymal transition. Proliferation and death of progenitors as well as early patterning of the heart appear normal. However, DiI labelling of second heart field progenitors revealed a defect in the addition of cells to the heart. RNA microarray analysis uncovered a set...

Progenitor cells in the right or left posterior SHF contribute to the right or left common atrium, respectively. Explant experiments with transgenic embryos,in which the transgene marks the right atrium, show...

.... Although the results are not strictly quantitative because we could not control the exact size of the DiI-labelled patch, they show quite clearly that the rate of precursor formation in these three regions is comparable. Thus, the pattern of nerve cell differentiation in hydra can not be explained...

... and the otic vesicle lateral to r5. Focal injections of DiI at the levels of r3 and r5 demonstrated that both of these rhombomeres generated neural crest cells. The segmental distribution of neural crest cells resulted from the DiI-labelled cells that originated in r3 and r5 deviating rostrally or caudally...
