Embryonic morphogenesis of the human pituitary.

Light microscopy methods were used to study the main stages in the organogenesis of the pituitary in human embryos at Carnegie stages (CS) 12-23. Rathke's pouch (RP) was shown to form as a traction fold over whole width of the roof of the stomodeum in embryos at CS 12 due to a flexure of the neural tube with which the epithelium had a tight anatomical relationship (the attached part of the anterior wall of the RP) in the median plane of the embryo. The rudiment of the hypothalamic infundibulum and neurohypophysis formed at CS 15, as a thickening of the posterior wall of the diencephalon.

Peroxiredoxin VI in human respiratory system.

Peroxiredoxins (Prxs) constitute a novel family of antioxidant proteins, which specifically prevent enzymes from metal-catalyzed oxidation. The localization of a member of the mono-cystein subfamily of Prxs, Prx VI in human respiratory system and its antioxidant properties were investigated. By immunoblotting, the Prx VI was found to be present in human respiratory epithelium.
