[Morphological equivalents of lymphocytic-epithelial interactions in kidney and liver regeneration].

The histo- and ultrastructure of the murine kidney and liver is studied 17 and 48 h, respectively, after unilateral nephrectomy or partial hepatectomy. The number of lymphocytes are found to be increased in these organs after the operation. They come in close contact with hepatocytes and renal tubular epithelial cells forming in some cases gap junctions.
