[The histochemistry of human endosalpingeal ciliated cells (author's transl)]

The human endosalpingeal ciliated cells are not a homogeneous cell population. They can be distinguished into mitochondria prominent and normal cells. The morphological appearance of ciliated cells was studied in organ culture using different hormones and hormone combinations in the culture media. Histological (HE, semithin sections) and histochemical methods (PAS, Alcian Blue, SDH, LDH, ATPase, 5'-Nucleotidase, acid and alkaline Phosphatase) were applied. Those mitochondria prominent ciliated cells which are seen in the native endosalpinx can in vitro also be determined mainly under the influence of steroid hormones (hydrocortisone and progesterone). In hormone free incubation media the apices of ciliated cells are separated. This will happen in hormone containing media, too, but with delay, however. Some results are in agreement with the possible transformation from ciliated cells to secretory cells.
