title: [The interrelation of the principal and intercalated cells of the collecting tubules in rats in postnatal ontogeny].
abstract: The study presents the results of quantitative analysis of interrelations of principal and intercalated cells of rat kidney collecting tubules in postnatal ontogenesis. (1, 3, 7, 10, 14, 21, 30 and 90 days). Analysis of total cell number dynamics in collecting tubule indicates greater cell increase in cortical segment, smaller one-in external and internal medullar segments. The presence of proximo-distal gradient, several fold prevalence of principal cells over intercalated ones and constant growth of each cell type number were found in the study of total number of principal and intercalated cells along collecting tubules in cortical and external medullar segment.
