  • Title: [Characteristics of the upper cell surface in cultures of normal and SV-40 virus-transformed epithelium of mouse kidney. Study with the aid of scanning electron microscopy].
    Author: Zakharova OS.
    Journal: Tsitologiia; 1976 Nov; 18(11):1311-4. PubMed ID: 196369.
    Abstract:
    Central cells of the normal epithelial sheet are sparsely covered by microvilli. Numerous microvilli were seen in the regions of intercellular contacts. Marginal cells of sheets had a finely developed lamellar cytoplasm (lameloplasm) with smooth upper surface at their free margins. A transformed cell line (MPTR) resembled normal parent cells by its ability to form monolayered sheets in cultures. More microvilli of increased length appeared on the upper surface of central MPTR cells. The normal structure of lamelloplasm was changed at the free edge of the MPTR sheets. It is suggested that abnormal cell attachment to the substratum may be responsible for the altered cell surface morphology (increased length of microvilli, defective, structure of lamelloplasm) in the MPTR cultures.
