The central channels may be round or show variation in shape, including undulating contours and papillary infoldings. Both tubular glands in the lobules and central cystic channels are lined by a single layer of tall columnar cells with clear, mucin-filled cytoplasm and basal, bland, round to oval nuclei with indistinct nucleoli (Figure 8, C).
The DP lobes are composed of acini small in diameter compared to the other lobes, which are lined by columnar epithelium with moderate infolding and occasional tufting, and are surrounded by a relatively dense stroma.
The extensive plasma membrane infoldings associated with mitochondria provide increased surface area and energy for active ion transport.
The convoluted tubules of normal rats contained basement membranes mitochondria nuclei infoldings and lamina (Fig.
They proposed that the palatal groove represents an infolding of the enamel organ and Hertwig's epithelial root sheath and parallels the pathogenesis of dens invaginatus.
5A), broadly exposed in dorsal view; dorsal rim broadly and shallowly emarginated along midline; infolding of dorsal rim broad, flat, about 2 times as long along midline as longitudinal diameter of posterior aperture, with broad and deep central impression around posterior aperture; lateral margin with a distinct tubercle at each side; infolding of ventral rim thick, its dorsal margin broadly convex; infoldings of dorsal and ventral rim with long, erect pilosity except central impression.
Cerebrospinal fluid (CSF) fills the spaces between the infoldings of the brain, the ventricular system in the brain, and the space surrounding the brain within the skull and is about 100 percent water.
Ultrastructural changes at this stage paralleled the biochemical findings in that the mitochondria were dramatically altered in size and shape and there was extensive loss of the basal plasma membrane infoldings together with complex cisternal proliferation in proximal tubular cells.
The hyperplastic follicular epithelium forms infoldings into the lumen of the follicle, producing a stellate outline.
(12) reported that the atypical P-ANCAs also show multiple intranuclear fluorescent foci, which likely correspond to infoldings of the nuclear envelope.
The epithelium of the genital chamber consists of a monolayer of cells which are characterized by basal membrane infoldings associated with mitochondria, thus forming a typical basal labyrinth (Fig.
