  • Title: [Analysis of cytoskeleton structural changes in the granular cells of the frog bladder during the stimulation of water transport].
    Author: Snigirevskaia ES, Komissarchik IaIu.
    Journal: Tsitologiia; 1987 Feb; 29(2):150-5. PubMed ID: 3495056.
    Abstract:
    Structural changes of the cytoskeleton of the frog urinary bladder granular cells were examined during low and high water permeability of the epithelium. A tight connection of the microfilaments and microtubules with vacuolar membranes and a great increase in the number of microtubules during a stimulated water flow was shown using different electron microscopic methods. Two populations of microtubules were discovered, respectively, with different diameter and different rate of stability. It is suggested that the thicker microtubules while interacting with actin microfilaments through associated electron dense globules may fulfil the transport function in the cell.
