Control of endothelial cell polarity and sprouting angiogenesis by non-centrosomal microtubules.

abstract：:Spatial and temporal cues are required to specify neuronal diversity, but how these cues are integrated in neural progenitors remains unknown. Drosophila progenitors (neuroblasts) are a good model: they are individually identifiable with relevant spatial and temporal transcription factors known. Here we test whether s...
