abstract：:Formation of tubular structures from an epithelial tissue is a process common to many morphogenetic events during organogenesis. We report here new data concerning the expression pattern of the vHNF1/HNF1beta gene during this process in the mouse. vHNF1 (variant Hepatocyte Nuclear Factor 1) is a member of the HNF1 hom...
