  • Title: [Leptofibrils in rat ventricular cardiomyocytes in vitro].
    Author: Martynova MG, Borisov AB.
    Journal: Tsitologiia; 1987 Jan; 29(1):17-21. PubMed ID: 3564157.
    Abstract:
    The presence of leptofibrils in ventricular myocytes of the heart of the 2- and 14-day old rats in 8-day old cultures was shown and their structure was investigated. Leptofibrils are seen only in myocytes on a definite stage of differentiation. Leptofibrils are attached to Z-bands running parallel or perpendicular to myofibrils. The period of their cross striation varies from 135 to 215 nm. Possible functions of the leptofibrils are discussed.
