whose mucosa was composed of fold- shaped transitional epithelium
which lines the inside of the organ and dense modeled connective tissue with elastic fibers.
Organization and differentiation of cells begin after 96 hours; transitional epithelium
is transformed into a layer of low cuboidal cells, which then differentiate into ciliated and goblet cells.
1995) who examined human urinary bladder by scanning electron microscopy, and indicated that collagen in the superficial portion provides support and protection for the transitional epithelium
against over-distention and in the middle and deep portions it supports and protects blood vessels and nerves against external forces.
In bladder, CYP1A1 was highly expressed in both endothelium (Table 3, Figure 2B) and transitional epithelium
forming the bladder mucosa (Table 2, Figure 3).
Ten specimens contained smooth muscle lying beneath stratified squamous or transitional epithelium
, suggesting that it was from the internal anal sphincter.
The small round cells (SRCs) most probably originated from the tubular epithelium of the kidney or the transitional epithelium
of the urinary tract.
Sections studied from TURBT specimen, shows native bladder tissue lined focally by transitional epithelium
