Spiral prominence epithelium.
Recent studies have shown neuroendocrine-type cells in human spiral prominence epithelium. A light microscopic and ultrastructural study was made on the guinea pig spiral prominence epithelium to try and identify neuroendocrine cells. The study showed that such cells were not present in the guinea pig spiral prominence epithelium. The spiral prominence epithelium was characterized by uniformity of cellular staining with Toluidine blue and the ultrastructural appearance. The morphology of the spiral prominence epithelium was similar to that previously described. The absence of neuroendocrine cells in spiral prominence epithelium in the guinea pig is discussed in relation to species differences.
