    Age-dependent morphological changes in the seminal colliculus in male mice (1979)
    Springer
    Anatomy and embryology 158 (1979), S. 1-12 
    Details
    ISSN: 1432-0568
    Keywords: Neonatal mouse seminal colliculus ; Developmental changes ; Scanning electron microscopy ; Ruffled cells
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary The developmental changes in the seminal colliculus of male mice were studied by light and scanning electron microscopy. The epithelium of the mouse seminal colliculus is transformed to the mature epithelium between 20 and 25 days of age, while the transformation of the remaining urethral wall occurred from 5 to 10 days of age. During the process of this epithelial transformation at the seminal colliculus unusual structures, including prominent epithelial proliferations and protrusions, were observed in the area adjacent to the ejaculatory duct openings and the ventral area of the upper medial region of the seminal colliculus in 15-day-old mice. In these unusual structures, three types of cells were recognized by their surface characteristics: cells which had distinct borders and ruffled cell surfaces with microridges; cells which had distinct borders and flat or slightly ruffled cell surfaces with many short microvilli, and small cells which had rounded cell surfaces with many long microvilli. In the remaining area of the seminal colliculus, two types of cells were distinguished: those which had flat or slightly rounded cell surfaces with many short microvilli and those cells with many long microvilli similar to the ones in the previously described area. In 25-day-old mice, the unusual protruding structures were not observed, but some cells with ruffled surfaces were still seen.

    The collicular recess organ: Evidence for structural and secretory specialization of the ventricular lining in the collicular recess (1977)
    Springer
    Cell & tissue research 184 (1977), S. 29-44 
    Details
    ISSN: 1432-0878
    Keywords: Collicular recess organ (Rat) ; Velum medullare ; Ceolocytes ; Circumventricular organs ; Ependyma
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary The collicular recess organ and adjacent portions of the collicular recess were studied by light microscopy, scanning electron microscopy and transmission electron microscopy. In the collicular recess, the ventricular wall contains folds and is well vascularized. The adluminal ependymal cells generally bear kinocilia and microvilli on their ventricular surface. Among the cilia, many secretory droplets, some axons, and few supraependymal cells are seen. Various stages of apocrine ependymosecretion are observed. In addition to tanycytes, coelocytes are found scattered throughout the ependymal lining of the collicular recess. Coelocytes, characterized by lumina containing cilia and a few microvilli, are accumulated in ependymal and hypependymal positions of the collicular recess organ at the roof of the collicular recess.
