[Intertubular cells and their relation to the renal cambium].
The intertubular cells (ITC) of the cortex of the human kidney (from the fetus, newborns, children aged from 1 to 5 years, adults aged from 30 to 70) were studied. The ITC in the kidneys with an undeveloped structure (fetus, newborns) amounted 21.4--12.6% of the epithelial cells of the convoluted tubules and for children over one year and adults--7.6%. When the kidney was affected by nephrotoxic poison (ethylene-glycol) and deep hypoxia and ITC were activated, began to multiply and made up 14.5% of the epithelium of the convoluted tubules. It is suggested that the ITC represented a peculiar cambium of the renal tubules which formed due to the transferring of a part of the cells of the metaneophrogenic tissue into position of rest (R-period).
