| Research Abstract |
We investigated the possibility that the initially proliferating cells （target cells） which are responsible for recovering the damaged proximal tubules are progenitor-like cells in tubules in acute kidney injury model of rat. The target cells showed unequal cell division which is characterized in stem cells and more than one such a cell located in the same nephron. ABC transporter as multiple drug resistant phenotype in the isolated target cells were not different from those in other proximal tubular cells, but the target cells were resistant to urnaly acetate and 5-fluorouracil. The data support the possibility that the target cells are tubular epithelial progenitor-like cells.
