... into type 1 cells (AT1s). BMP signaling is active in AT2s and TASCs, transiently declines post-PNX in association with upregulation of antagonists, and is restored during differentiation of AT2s to AT1s. In organoids, BMP4 inhibits AT2 proliferation, whereas antagonists (follistatin, noggin) promote AT2...

... sufficient for neural induction, Tbx3-expressing pluripotent cells only form retina in the context of the eye field. Unlike Tbx3, the neural inducer Noggin can generate retina both within and outside the eye field. We found that the neural and retina-inducing activity of Noggin requires Tbx3. Noggin...

In this study, we dissected regulatory functions of BMP and Wnt pathways in early tooth development using a transgenic noggin ( Nog ) overexpression model ( K14Cre;pNog ). It exhibits early arrested tooth development, accompanied by reduced cell...

... rise to ameloblasts, which generate enamel, and little is known about the function of microRNAs in this process. Here, we describe the role of a novel Pitx2:miR-200c/141:noggin regulatory pathway in dental epithelial cell differentiation. miR-200c repressed noggin, an antagonist of Bmp signaling. Pitx2...

... that both Noggin proteins, if ectopically produced in sufficient concentrations in Xenopus embryo, can induce a secondary head, including the forebrain. During normal development, however, Noggin1 mRNA is translated in the presumptive forebrain with low efficiency, which provides the sufficient protein...

... phenotype, suggesting that Gsc has Chd-independent functions in DV patterning. Even more striking was that Gsc elicited complete secondary axes in the absence of three secreted BMP antagonists, Chd, Follistatin-like 1b and Noggin 1, suggesting that Gsc functions in parallel with secreted BMP inhibitors. Our...

Rostral transplantation of either the caudal-most somites or caudal-most NT reveals that the observed features of caudal-most NCCs relate to properties intrinsic to these cells. Furthermore...

..., but the mechanistic relationship with Nodal expression remains unclear. We find that BMP signal transduction is higher in the right LPM, although Bmp4 , which is required for L-R patterning, is expressed symmetrically. By contrast, the BMP antagonists noggin (Nog) and chordin (Chrd) are expressed at higher levels...

Furthermore, Nog overexpression suppressed EMT and arrested ingressive cell movement in the chick VER...

By contrast, the Bmp antagonist noggin is expressed dorsally in neural folds containing DLHPs,noggin - null embryos show markedly reduced...

Msx1 downregulation thus correlates with the formation of the pterylae, and its maintenance...

We report that the expression pattern of mouse HtrA1 shows a striking correlation with the sites where signaling of the Tgfβ family...
