WebThe development of kidney tubules involves reciprocal induction by the ureteric bud and surrounding mesenchyme 3 Wnt9b. As the mesenchyme cells start to condense, they express a matrix glycopro-tein, syndecan, on their surface. This condensing stage is followed by the formation Web2 days ago · Here, we show that endogenous cell competition occurs and intrinsically correlates with the Axin2 expression level during normal brain development. Induction of genetic mosaicism predisposes Axin2-deficient NPCs to behave as “losers” in mice and undergo apoptotic elimination, but homogeneous ablation of Axin2 does not promote cell … shy napoleon believed in marriage
