[Mitosis in the tubular epithelium of allotransplanted dog kidney during the early periods following transplantation].

Cells dividing by mitosis were revealed in the tubular epithelium of 5 of 23 allografted kidneys of mongrel dogs. These mitoses were localized in the proximal and distal convoluted tubules (88 and 21 mitoses, respectively). Four pathological mitoses among 29 dividing epithelial cells were revealed 3 and 5 days after the operation, whereas no pathological mitoses were found among 80 mitoses of the kidneys present in the recipient's organism for 1 and 2 days. No mitoses were observed in the tubular epithelium of control kidneys (in the unoperated dogs).
