A method based on light reflectometry was designed to study possible rapid effects of P4 on the tubal ciliary beat frequency CBF of mice ex vivo. Mats Löfgren ; Umeå universitet. The fallopian tube serves to transport the egg and spermatozoa to achieve fertilization. In humans, the variation in receptor expression over the menstrual cycle showed similarities to the regulation observed in mice before, around and after ovulation. Allopregnanolone and pregnanolone neuroactive metabolites of progesterone act as positive modulators of the GABAA receptor system which is the major inhibitory system in CNS.

Later, the formation of the pre-embryo is thought to result from the movement of cilia in the epithelium and the muscular activity in the wall of the fallopian tube.

The role of progesterone in the regulation of ciliary activity in the fallopian tube

Progesterone has been reported to be a survival factor in granulosa cells at several developmental stages. Charlotte Öfverman ; Umeå universitet. A method based on light reflectometry was designed to study possible rapid effects of P4 on the tubal ciliary beat frequency CBF of mice ex vivo. Immunohistochemistry IHCconfocal microscopy, Western blot, reverse transcriptase PCR and real time PCR were used to detect and confirm the expression and specific cellular localization of the mPRs in the fallopian tube. The overall aim of this thesis was to investigate the distribution and regulation of membrane progesterone receptors mPRs that may be involved in regulating ciliary activity in the fallopian tube. In conclusion, this study demonstrates that mPRs are present in the ciliary cells of mouse and human fallopian tubes and that P4 can regulate ciliary activity within the fallopian tube.

    I am in love with her because of all the shit she does with black guys. Especially anal. The fact that she lets black guys fuck her in the ass literally makes me want to smell, lick and taste her asshole. She is truly the best.
