Abstract. Cellular pleomorphism is a characteristic feature of amniotic fluid examined microscopically immediately following amniocentesis. Multiple cell types (with differing sites of origin) adhere to glass or culture vessels within hr of plating (see Chapter 9 for more details). Amniotic Fluid Cell Culture.

In book: Genetic Disorders and the Fetus, Sixth Edition, pp - Amniotic fluid cell cultures occasionally contained also large multinucleated cells (E-5 Amniotic fluid cell culture consists of a heterogeneous cell population displaying a range of morphologies and behaviors.

The low viability and small number of amniotic fluid cells available, the uncertainty as to their tissue origin, and culture contamination are the reasons for the relatively low success rate in cultivating amniotic fluid cells in vitro.

Out of a total of amniocenteses performed in this laboratory from the 13th to the 24th week of gestation /amniotic-fluid-cell. Human amniotic fluid (hAF) is known to contain multiple cell types and recently, it was demonstrated that lines of broadly multipotent cells (hAFS cells) are present in AF that can give rise to adipogenic, osteogenic, myogenic, endothelial, neurogenic, and hepatic lineages, inclusive of all embryonic germ layers [80].

This study carefully /amniotic-fluid. Amniotic fluid cell cultures occasionally contained also large multinucleated cells (E-5), which appeared to contain large amount of fibrillar keratin.

Fibroblastic cells, identified by their decoration only with antibodies against vimentin, were rarely found in amniotic fluid cell ://   Controversy exists in the literature concerning the significance of the presence of leukocytes in amniotic fluid.
