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. It occurs more often 48 h after operation. The number of leukocytes is found to be increased also especially in the regenerating liver in which many hepatocytes with cytoplasm partial necrosis are found. Only single epithelial cells are involved in the destruction in the kidney. Possibility of lymphocyte participation in the morphogenetic function realization is discussed.
