Review: The feto-placental unit, pregnancy pathology and impact on long term maternal health.

abstract：:Placental trophoblast syncytialization is a unique biological process. We have studied the time course of this process using DNA microarray in a cell model of syncytialization (the cytotrophoblast cell line BeWo following increased intracellular cAMP by forskolin). Total RNA was extracted from BeWo cells and labelled-...
