Control of cell pattern in the neural tube: regulation of cell differentiation by dorsalin-1, a novel TGF beta family member.


Basler, K; Edlund, T; Jessell, T M; Yamada, T (1993). Control of cell pattern in the neural tube: regulation of cell differentiation by dorsalin-1, a novel TGF beta family member. Cell, 73(4):687-702.

Abstract

Distinct cell types differentiate along the dorsoventral axis of the neural tube. We have cloned and characterized a novel member of the TGF beta gene family, dorsalin-1 (dsl-1), that appears to regulate cell differentiation within the neural tube. dsl-1 is expressed selectively in the dorsal neural tube, and its pattern of expression appears to be restricted by early signals from the notochord. Exposure of neural plate cells to dsl-1 promotes the differentiation of cells with neural crest-like properties and inhibits the induction of motor neurons by signals from the notochord and floor plate. These findings suggest that dsl-1 regulates the differentiation of cell types along the dorsoventral axis of the neural tube, acting in conjunction with distinct ventralizing signals from the notochord and floor plate.

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.
