carcinoma of the lungs: the first report of a case in Egypt and review of the literature.
Indeed, these three NOS isoforms were highly expressed in alveolar cells
in the lung tissue of urethane-injected mice.
Alcian blue stains acid mucosubstances and acetic mucins. Because type II alveolar cells
secrete surfactant, the majority of which is dipalmitoylphosphatidylcholine, the alcian blue dye will give a blue color to mucopolysaccahrides present in or on the cells.
Comparison of mitochondria density and average volume of type II alveolar cells
in fetal rats of four groups showed that the mitochondria density intype II alveolar cells
of Group A (20.44 [+ or -] 4.99 [micro][m.sup.-3]) was significantly lower than that of Group B (31.46 [+ or -] 3.45 [micro][m.sup.-3]), P < 0.01; the density between Group B and Group C had no statistical difference, P > 0.05.
Figure 2 summarizes the signaling effects mediated by the various alveolar cells
in response to xenobiotic exposure.
Differentiation of MSCs into epithelial type II cells may partially restore the stem cell pool, leading to increased genesis of alveolar cells
for the resolution of disrupted alveolar surfaces, thereby augmenting the repair process.
Among other complications, tobacco smoke down regulates vascular endothelial growth factor, which is required for the growth and survival of endothelial and alveolar cells
. Tobacco smoke also increases the numbers of neutrophil elastase and macrophage proteinases in the lungs of smokers.
In rats exposed to BNF alone, Bax was rarely expressed (Figure 2C), but it was frequently expressed in alveolar cells
from rats exposed to CD and BNF (Figure 2D).
The scatterers are alveolar cells
in the barbs of the feathers.
TAZ expression levels in the alveolar cells
of NSIP cellular-type patients tended to be higher than those of the fibrotic-type patients, but the difference was not statistically significant [Figure 1]c.
It has been established that bronchial cells are less permissive to invasion than alveolar cells
With respect to ultrastructural histopathologic changes by electron microscopy, Type I alveolar cells
were characterized by vacuolation, degranulation, mitochondrial swelling, perinuclear cisterna dilation, and rough endoplasmic reticulum pool after inhalation injury, while Type II alveolar epithelial cells were typically characterized by vacuolation of lamellar bodies and exfoliated tubular myelin.
