Abstract
We found that many Wnt-signaling genes were dynamically regulated, with an immediate decrease, followed by an eventual normalization during memory consolidation. This rapid decrease in Wnt mRNA was confirmed with individual quantitative PCR and in situ hybridization. We then manipulated Wnt signalin...

Abstract
We use Drosophila to explore the as yet unknown mechanisms regulating this privileged tissue growth. As in mammals, we observe in Drosophila that the CNS is more highly spared than other tissues during nutrient restriction (NR). We demonstrate that anaplastic lymphoma kinase (Alk) efficiently protec...

Abstract
We selected gelatin as ECM (extracellular matrix) to support differentiation of mES (mouse embryonic stem) cells into TE (trophectoderm), as gelatin was less expensive and widely used. We found that 0.2% and 1.5% gelatin were the suitable concentrations to induce TE differentiation by means of detec...
