Phylogenic distribution of human renal antigens defined by monoclonal antibodies

The preparation fo five monoclonal antibodies specific of important human renal histologic structures both functionally and organogenetically has permitted to identify the repartition of the corresponding antigens in the vertebrate phylum. For three of them, appeared a clear cut histologic identity in intensity and localization between the mammals studied and man. For the two others a phylogenic and histologic dispersion was observed. It may be supposed, in the latter case, that the evolution and the biotope have acted in different manners on renal function and organogenesis according to the vertebrate classes or species investigated.
