We studied the in-vitro secretory function of non-polarized and polarized
cultured Fallopian tube epithelial cells by measurement of the placental
protein 14 (PP14) secretion in primary cultures and subcultures from
Fallopian tubes obtained from eight premenopausal women in different phases
of the ovarian cycle. Primary cultures were established in minimal
essential medium in Earle's salts supplemented with fetal bovine serum and
the cells were subcultured for six passages, in the polarized cell
cultures, the cells being seeded on an extracellular matrix system. Cell
freezing was carried out using 10% dimethyl sulphoxide. PP14 secretion into
the culture media was measured by a radioimmunoassay using 125I-PP14 as
label and rabbit anti-human PP14 serum. There was a large amount of PP14
secretion into the culture media in primary cultures, the secretion
decreasing considerably after subculture 1. PP14 secretion after subculture
2 was not different from the control values. Polarized and non-polarized
cells secreted similar amounts of PP14 and frozen-thawed cells did not
appear to secrete PP14. Epithelial cells from Fallopian tubes obtained at
different phases of the ovarian cycle did not appear to show any difference
in PP14 secretion rates. Our data suggest that the in-vitro secretion of
PP14 by human Fallopian tube epithelial cells is adversely affected by cell
ageing and freezing.
