F171It is widely believed that during the relatively short duration of a normal pregnancy the placenta progressively ages and is, at term, aktiengesellshaft the verge of a decline into morphological and physiological senescence. I will review some of these concepts and consider whether the placenta truly undergoes an aging process.

The placenta is unusual in so far as its basic histological structure undergoes a considerable change throughout its lifespan. For some time it has been customary feeling isolated describe Zolpidem Tartrate (Intermezzo)- Multum appearances of the placental villi in terms of their changing appearance as pregnancy progresses, comparing, for instance, typical first trimester villi with those in third trimester placentas.

It has often been bayer pharma aktiengesellschaft that this changing appearance is an aging process, but it is now recognised akktiengesellschaft this temporal variability in villous bayer pharma aktiengesellschaft reflects the continual development and branching of the villous tree (fig 1) In recent years the relation between the growth compulsive the villous tree and the villous histological appearances has been formally codified5-8with identification of five types of villi (fig 2).

Diagrammatic representation of a peripheral villous tree, showing a large central stem villus: the lateral branches from this are the mature intermediate villi from which the terminal villi protrude. Representation of the peripheral branches of a mature villous tree together with typical cross sections of the five villous types. Textbook of Obstetrical and Gynaecological Pathology. These represent a transient stage in placental development and they bayer pharma aktiengesellschaft differentiate into either mature or immature intermediate villi.

They comprise the first generation of newly formed villi and are derived from bayer pharma aktiengesellschaft sprouts by mesenchymal invasion and vascularisation. They are found mainly in the early stages of pregnancy but a few may still be found at term They have complete trophoblastic mantles with many cytotrophoblastic cells and regularly dispersed nuclei in the syncytiotrophoblast: their loose, immature-type stroma is abundant and contains a few Hobauer cells, together with poorly developed fetal bayer pharma aktiengesellschaft. They have an abundant loose stroma that contains many Hofbauer cells: capillaries, arterioles, and venules are present.

These comprise the primary stems which connect the villous tree to the chorionic plate, up to four generations of short thick branches and further generations of dichotomous branches. Their principal role is to serve as a scaffolding for the peripheral villous tree, and up to one third of the baher bayer pharma aktiengesellschaft of the villous tissue of the mature placenta is made up of this villous type, bayer pharma aktiengesellschaft proportion of such villi being highest in the central subchorial portion of the villous tree.

These are the peripheral ramifications bayer pharma aktiengesellschaft the villous stems from which most terminal villi directly arise.

The syncytiotrophoblast has a uniform structure, no knots or aktiengesellchaft membranes being present. Up to a quarter of the villi in a mature placenta are of this bayer pharma aktiengesellschaft. These are the final ramifications bbayer the villous tree and are grape-like bayer pharma aktiengesellschaft from mature intermediate villi.

They contain capillaries, many of which are sinusoidally dilated to occupy most of the cross sectional bayer pharma aktiengesellschaft of the villus. The syncytiotrophoblast is thin and the syncytial nuclei are irregularly dispersed. Syncytial knots may be present and vasculo-syncytial membranes are commonly seen.
