  • Title: An ultrastructural study of mitotic chondrocytes in the proliferative zone of the rat tibial growth plate.

    Journal: Ann Anat; 1993 Feb; 175(1):41-5. PubMed ID: 8465973.
    Abstract:
    Mitotic chondrocytes containing fairly prominent cell organelles were observed in the proliferative zone of the rat tibial growth plate by electron microscopy. During the later stage of mitosis, the endoplasmic reticulum was mostly vacuolated, and the Golgi stacks were replaced by spherical and cylindrical vacuoles and small vesicles. The cytoplasmic division began at early telophase. However, the cytoplasmic cleavage furrow was so narrow that dividing chondrocytes looked as if they were partitioned by a slit. This is probably one reason for the appearance of the binuclear cells that are occasionally observed in the tibial growth plate.
