Summary
Findings
At high power, this plastic section of a mucosal fold in
the fallopian tube shows the structure of the mucosa in
greater detail. Note the ciliated cells and peg cells
whose apices protrude into the lumen. Numerous blood
vessels are present in the subjacent lamina propria.
Comment
In addition to a regional distribution of ciliated and
nonciliated epithelial cells discussed in the comment
with the previous image, the relative distribution of
these cell types changes during the menstrual cycle.
Estrogen produced during the first half of the menstrual
cycle (follicular phase) stimulates ciliogenesis in
the Fallopian tubes, whereas progesterone increases the number of secretory peg cells during the second half of the cycle (luteal phase).
