title: Development of the human renal inner medullary interstitial cells.
abstract: Two cell types were identified in the inner medulla and papilla of four fetal kidneys of 16 1/7-, 17 3/7-, 21 1/7- and 25 5/7-week-old (menstrual): undifferentiated mesenchymal cells and some highly differentiated cells which contained some lipid granules, lysosomes, smooth and rough endoplasmic reticulum. The structure of these cells resembled the two cell types which were observed in the adult tissue.
