Slugexpression during organogenesis in mice

The vertebrate Sluggene encodes a zinc finger-containing transcriptional repressor. Here we report expression of the mouse Sluggene during organogenesis and late fetal development using histochemical detection of ß-galactosidase expressed from a targeted SluglacZknock-in allele. The Sluggene is highly expressed in the mesenchymal or stromal component of numerous organs. It is also highly expressed in craniofacial mesenchyme, in bone of both mesodermal and neural crest origin, and in the outflow tract and the endocardial cushions of the heart.
