The formation and fate of the blastoderm epithelium of the , embryo, equivalent of the blastula stage of other animal groups. It is an extremely transient structure which, as soon as it is formed, is rapidly converted into a multi-layered embryo. Thus, it is an epithelium of particular interest because of its mode of formation and the forces which transform it, rath

Development of kidney epithelial cells,ut of the tubular fluid. The proper execution of these vectorial transport processes depends on the polar nature of the epithelial cells. The functional importance of the polar nature of the epithelial cells is well illustrated in the kidney but has considerably broader physiological significance, a

Cytoskeletal components in intestinal brush border morphogenesis: an evaluation of their function,plies the existence of distinct domains of the plasma membrane and an asymmetric distribution of the cytoskeletal network. Their apical surface, facing the external milieu, develops a unique structure named the brush border which provides a greatly expanded absorptive surface facilitating the uptake

The role of yolk sac and gut epithelial cells in maternal immunoglobulin transport,al) compartment, but in certain situations this is a prerequisite for survival. For instance, all mammals acquire maternal antibodies, either from the mother’s blood or uterine fluid during their development . or from the colostrum and milk when suckling commences. Such antibodies provide the foetus

Functional interplay between extracellular matrix and extracellular matrix-degrading proteinases inow evident that, in addition to soluble factors such as hormones and growth factors, the interaction of an epithelial cell with its micro-environment and with adjacent cells is critical in regulating tissue specificity. Earlier studies showed an inductive role of mesenchyme on epithelial growth and

Salivary epithelium branching morphogenesis,t deal about the requirements for normal development in this organ. The submandibular salivary gland first appears late on day 12 of gestation in the mouse and on day 13 in the rat. The initially broad primordium arises from the oral epithelium and forms a stalk (primary duct) and a bulbous lobule.
