Molecular mechanisms of growth cone guidance: stop and go?


Stoeckli, E T (1997). Molecular mechanisms of growth cone guidance: stop and go? Cell and Tissue Research, 290(2):441-449.

Abstract

Evidence from pathfinding studies in both vertebrates and invertebrates indicates that growth cones are not guided by simple stop or go signals. Rather, the navigation of growth cones through the preexisting tissue is controlled by a continuous integration of both positive and negative cues. The path taken by an axon is determined by the continuously changing situation encountered by the growth cone at any given site along the trajectory of the axon to the target. The signals derived from interactions of surface molecules with these cues provided by the environment of the growth cone are constantly changing both temporally and spatially. Therefore, each growth cone encounters a unique set of guidance cues directing it to its specific target, thus allowing for the tremendous complexity required for the guidance of millions of axons in the developing nervous system.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
