“…D'autre part, le cil issu d'un des centrioles du dipiosome se d6veloppe normalement lorsque la ciliogen~se a lieu dans une cellule indiffdrenci6e, alors qu'il reste g6n6ralement rudimentaire chez les cailles en ponte. Comme nous l'avons indiqu6 dans l'article pr6c6dent, les m6ca-nismes de la ciliogen~se sont comparables h ceux d6crits dans d'autres 6pith61iums (17,18,5,1,4,2). Quels que soient les traitements, nous retrouvons syst6matiquement l'association des masses fibreuses et de la face de formation de l'appareil de Golgi, association que nous avons d~j~ signal6e (article I).…”

The hormonal control of ciliogenesis and transformation of mucous cells was studied in the oviduct (magnum) of ovariectomized quails. Estradiol benzoate induces ciliogenesis with doses varying from 10 t~g/day to 100 txg/day after 6 days of treatment. With 100 txg/day, differentiation of some mucous cells is also induced as well as the formation of transitory "mixed cells" which are in the process of ciliogenesis and contain mucous granules.Associated with progesterone (1 mg/day), estradiol benzoate (10 txg/day) induces the differentiation of mucous cells and ciliated cells. The luminal epithelium of quails injected with this mixture is similar to the luminal epithelium observed in the oviduct of laying quails. With the same dose of progesterone (1 mg/day) and 20 ~g/day of estradiol benzoate for 6 days, ciliogenesis is completely inhibited. All epithelial cells are secretory cells.Transformation of 50% of the mucous cells into ciliated cells is obtained by following the previous estradiol-progesterone treatment with the injection of estradiol benzoate (20 /zg/day) for 3 days. Divisions of mucous cells were also observed. It is also possible to induce ciliogenesis in some mucous cells by withdrawing both hormones for 3 days. In this case, no cell divisions were observed.La ciliogen~se s'effectue spontan6ment dans les cellules ~ mucus de l'6pith61ium du magnum des cailles en ponte (article I), mais ce ph6nom~ne n'int6resse qu'une faible proportion des cellules. Dans le but de d6montrer la transformation de cellule h mucus en cellule cili6e, nous avons cherch6 ~ reproduire et ~ g6n6raliser ces transformations par des traitements hormonaux chez des cailles castr6es.Bien que le magnum des oiseaux soit un organe cible des hormones st6roides particuli~rement 6tu-di6, le contr61e hormonal de la ciliogen~se n'a pas 6t6 jusqu'ici clairement d6montr6. Aussi, avant de provoquer la transformation des cellules h mucus en cellules cili6es, nous avons cherch6 h contr61er, chez des cailles ovariectomis6es, la diff6renciation des cellules ~pith61iales soit en cellules cili6es, soit en cellules h mucus.

During passage through the oviduct, the egg of Xenopus laevis acquires the following substances or envelopes: electron-dense particles in the vitelline coat, the prefertilization layer in and around the vitelline coat, and four layers of jelly. Both gross anatomical observation and light and scanning or transmission electron microscopic observations of various levels of oviduct revealed that the first two are produced in the pars recta 1 and 2 portions, and that jelly layers 1-4 are added in the pars convoluta 1-4 respectively. The relative lengths of these portions were 0-0.044, 0.044-0,055, 0.055-0.52, 0.52-0.70, 0.70-0.87 and 0.87-1.00 from anterior to posterior. Along the whole length of the oviduct, the epithelium was comprised of ciliated cells and various types of secretory cells. Except for the pars recta 1 portion, there were two or three types of secretory cells in each portion of the oviduct, indicating that the structure of each stratum of the egg envelope is formed by an interaction of products from the specific types of secretory cells in each portion of the oviduct.
