Wnt-β-catenin signaling initiates taste papilla development
It is demonstrated that Wnt-β-catenin signaling is activated in developing fungiform placodes and taste bud cells and altered regulation of this pathway may underlie evolutionary changes in taste papilla patterning. Expand

It is demonstrated that Shh-expressing embryonic taste placodes are taste bud progenitors, which give rise to at least two different adult taste cell types, but do not contribute to taste papillae. Expand

FGF Signaling Regulates the Number of Posterior Taste Papillae by Controlling Progenitor Field Size
This work reports that a balance between Sprouty (Spry) genes and Fgf10, which respectively antagonize and activate receptor tyrosine kinase (RTK) signaling, regulates the number of CVPs, and provides the first demonstration of the role of epithelial-mesenchymal FGF signaling in taste papilla development.

Establishment of new mouse embryonic stem cell lines is improved by physiological glucose and oxygen.
Culturing of cells derived from murine blastocysts in physiological oxygen and glucose reduces oxidant stress, which increases the success of establishing new embryonic stem cell lines, and none of the culture conditions prevents cytogenetic instability with prolonged passage. Expand
In Vivo Fate Tracing Studies of Mammalian Taste Cell Progenitors
F Fate mapping studies using tissue specific cre strains crossed with reporter alleles would uncover unique features in the formation of these specialized sensory cells and also provide us with an in vivo model system for taste organ specific experimental manipulations during development. Expand
AMP-activated protein kinase mediates effects of oxidative stress on embryo gene expression in a mouse model of diabetic embryopathy
Stimulation of AMPK in embryos during a diabetic pregnancy mediates the effects of hyperglycaemia-induced oxidative stress to disturb the expression of the critical Pax3 gene, thereby causing NTDs. Expand
β-Catenin signaling regulates temporally discrete phases of anterior taste bud development
Conditional genetics in the developing mouse embryo reveals discrete spatiotemporal functions of β-catenin in taste papilla morphogenesis and taste bud differentiation. Expand

It is shown that trocarin also causes edema in the mouse footpad; the inflammation, accompanied by a large purplish clot, is more persistent than the transient edema caused by FXa. Expand
Development of the Taste System
Improvements in understanding of the molecular, cellular, and tissue-level mechanisms driving the embryonic development of several components of the taste system of vertebrates are made, as has comparison with findings in other model developmental systems, including amphibians. Expand
