“…Furrows (i.e., "cushions") similar to those found in renal casts were observed in a variety of organs. Our identification of these furrows as indentations of cushions in replicated cerebral, coronary, and ophthalmic arteries is consistent with previous histological studies Azzam, 1963a, 1963b;Rosen, 1967;Kojimahara and Ooneda, 1980;Yohro and Burnstock, 1973;Moffat, 1969;Jellinger, 1974;Lange and Halata, 1979). Although cushions have never been described in adrenals, testes, liver, spleen, and intestinal tract, their presence in these organs may be inferred from the present studies.…”
