Freeze-etching study of intercellular junctions in the rat developing neural tube.
The intramembranous organization of the neuroepithelial intercellular junctions in the rat neural tube on days E13 and E15 was studied by using the freeze-etching technique. Tight junctions, frequently altered, are distinguished as the predominant type of intercellular junctions. Relatively rare gap junctions like intramembranous particle aggregations of varying sizes and particle packing occur too. The possible formation or breakdown of these probably temporary cell junction specializations is discussed.
