Microtubule Organization and Function in Epithelial Cells

Open access
Müsch, Anne·2004·Traffic

Abstract

Microtubules are essential for many aspects of polarity in multicellular organisms, ranging from the asymmetric distribution of cell‐fate determinants in the one‐cell embryo to the transient polarity generated in migrating fibroblasts. Epithelial cells exhibit permanent cell polarity characterized by apical and basolateral surface domains of distinct protein and lipid composition that are segregated by tight junctions. They are also endowed with a microtubule network that reflects the asymmetry of their cell surface: microtubule minus‐ends face the apical‐ and microtubule plus‐ends the basal domain. Strikingly, the formation of distinct surface domains during epithelial differentiation is accompanied by the re‐organization of microtubules from a uniform array focused at the centrosome to the noncentrosomal network that aligns along the apico‐basolateral polarity axis. The significance of this coincidence for epithelial morphogenesis and the signaling mechanisms that drive microtubule repolymerization in developing epithelia remain major unresolved questions that we are only beginning to address. Studies in cultured polarized epithelial cells have established that microtubules serve as tracks that facilitate targeted vesicular transport. Novel findings suggest, moreover, that microtubule‐based transport promotes protein sorting, and even the generation of transport carriers in the endo‐ and exocytic pathways.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
