(A) The model group with microvilli
sloughing and mitochondria stretching, marked with 1 and 2 respectively; (B) Blank group with normal goblet cells and intestinal villi, marked with 3 and 4 respectively; (C) Positive drug group with microvilli
shortening and membrane of goblet cells damaged, marked with 5 and 6 respectively; D and E were for CK group and TP group with integral microvilli
, marked with 7 and 8, normal cell-cell junction and nuclear membrane, marked with 9 and 10, respectively.
Otherwise, less normal distal convoluted tubule cells were observed with microvilli
and with vacuolated cytoplasm.
Electron microscopic finding of degenerated cells in lumen of PCT and abnormal arrangement of microvilli
in aged rats showed improvement after green tea administration.
this is particularly relevant for our intestinal villi and microvilli
Biologists, clinicians, and other researchers from the US, Asia, and Europe address the basic molecular mechanisms of cell polarity, such as the roles of membrane lipids and proteins involved in membrane trafficking, including the exocyst and molecular trafficking machinery; specific modifications of the cell surface, such as cilia and microvilli
, as well as laminins; the membrane trafficking of the transporters involved; and how epithelial cells are a barrier to interaction with the microbiome.
Visualization of mucosal layer of intestinal tract with SEM under higher magnification revealed that the microvilli
were densely arranged on the surface of mucosal membrane of anterior intestine and abundant secretory gland cells were be mingled with columnar cells.
Like sabellids (Lawrence and Krasne, 1965; Ermak and Eakin, 1976), the cerebral ocellar photoreceptors of serpulids are rhabdomeric in nature, with the elaborated photoreceptive membranes being formed from microvilli
that project into a pigment cup (Figs.
Acute exposures did not have much effect, but chronic exposure diminished the absorptive projections on the surface of intestinal cells called microvilli
, showed the findings published in the journal NanoImpact.
The liver cells in turn are covered with microvilli
- fingerlike protrusions that "massively enlarge" the cell surface area in contact with blood, said Dr Markus Heim, a liver researcher at the University of Basel.
In nasal septa that were only exposed to P multocida for two hours, the bacteria adhered to the microvilli
and cilia of the corresponding cells.
SEM micrograph (Figure 1(b)) of the nontreated cells revealed a semi-flattened surface structure containing microvilli
with extending lamellipodia known as membrane ruffles.
