Anti-PIGF polyclonal antibody

The most widely accepted theory for the development of preeclampsia is the "two-stage theory". An imbalance between antiangiogenic and proangiogenic factors is considered the link between the two stages. Nowadays, an increasing amount of data is available on the use of measurements of serum concentrations of these factors in the prediction, diagnosis and management of preeclampsia. The most useful, modern biochemical test that may help in making crucial clinical decisions in patients with preeclampsia is the sFlt-1/PIGF (soluble fms-like tyrosine kinase 1/placental growth factor) ratio. The aim of this review is to present the current use of different biochemical tests in the prediction, diagnosis and management of preeclampsia. Development of these diagnostic methods in recent years and a belief in their ground-breaking role in modern management of preeclampsia make this review especially important.

In response to injury, the myocardium hypertrophies in an attempt to maintain or augment function, which is associated with ventricular remodeling and changes in capillary density. During the compensatory phase of the hypertrophic response, the myocardium maintains output and is characterized by a coordinated neo-angiogenic and fibrotic response that supports cardiomyocyte health and survival. Emerging evidence shows that paracrine-mediated cross talk between cardiac myocytes and nonmyocytes within the heart is critical for cardiac adaptation to stress, including the extent of hypertrophy and angiogenesis. This review discusses recent results indicating that placental growth factor (PGF; also called PlGF), a secreted factor within the vascular endothelial growth factor superfamily, is a pivotal mediator of adaptive cardiac hypertrophy and beneficial angiogenesis through its ability to coordinate the intercellular communication between different cell types in the heart.
