Intravenous delivery of mesenchymal stem cells (MSCs) prepared from adult bone marrow reduces infarction size and ameliorates functional deficits in rat cerebral ischaemia models. Placental growth factor (PlGF) is angiogenic to impaired non-neural tissue. To test the hypothesis that PlGF contributes to the therapeutic benefits of MSC delivery in cerebral ischaemia, we compared the efficacy of s...

OBJECTIVE To compare the maternal serum concentration of placental growth factor-1 (PlGF-1) and PlGF-2 at 11-13 weeks' gestation in normal pregnancies and in those complicated by preeclampsia (PE), delivery of small for gestational age (SGA) neonates and fetal trisomies 21, 18 and 13. METHODS Serum PlGF-1 and PlGF-2 were measured in 270 pathological pregnancies (PE, n = 80; SGA, n = 80; triso...

Placenta growth factor (PlGF; formerly PGF), a vascular endothelial growth factor gene family member, is expressed in human implantation sites by maternal uterine NK (uNK) and fetal trophoblast cells. Lower than normal concentrations of blood and urinary PlGF have been associated with impending onset of pre-eclampsia, a hypertensive disease of late human gestation characterized by limited intra...

BACKGROUND Chronic pulmonary obstructive disease (COPD) has become the fourth leading cause of death worldwide. Cigarette smoking induces neutrophil elastase (NE) and contributes to COPD, but the detailed mechanisms involved are not fully established. In an animal model of pulmonary emphysema, there are increased expressions of placenta growth factor (PlGF) and lung epithelial (LE) cell apoptos...

Airway hyperresponsiveness (AHR) affects 55%-77% of children with sickle cell disease (SCD) and occurs even in the absence of asthma. While asthma increases SCD morbidity and mortality, the mechanisms underlying the high AHR prevalence in a hemoglobinopathy remain unknown. We hypothesized that placenta growth factor (PlGF), an erythroblast-secreted factor that is elevated in SCD, mediates AHR. ...

OBJECTIVE To estimate the value of first or second trimester placental growth factor (PlGF) as an additional antenatal screening marker for Down syndrome. DESIGN Nested case-control study. SETTING Antenatal screening service. POPULATION OR SAMPLE 532 Down syndrome pregnancies and 1,155 matched unaffected pregnancies. METHODS Stored maternal serum samples (-40°C) were assayed for PlGF. M...

Placental growth factor (PlGF) is a member of the vascular endothelial growth factor (VEGF) family of angiogenesis factors. It has the highest expression level in the endothelium as compared to other VEGF family members and plays an important role in pathological neovascularization. 1 In humans, four isoforms of PlGF exist (PlGF-1 through 4). Mice only express a single isoform of PlGF which is ...

OBJECTIVE Chronic kidney disease (CKD) and preeclampsia (PE) may both present with hypertension and proteinuria in pregnancy. Our objective is to test the possibility of distinguishing CKD from PE by means of uteroplacental flows and maternal circulating sFlt-1/PlGF ratio. DESIGN Prospective analysis. POPULATION Seventy-six patients (35 CKD, 24 PE, and 17 other hypertensive disorders), with...

Neuroblastoma (NB) is the most common extracranial solid tumor of childhood and is a rapidly growing, highly-vascularized cancer. NBs frequently express angiogenic factors and high tumor angiogenesis has been associated with poor outcomes. Placental growth factor (PlGF) is an angiogenic protein belonging to the vascular endothelial growth factor (VEGF) family and is up-regulated mainly in patho...

Placental growth factor (PlGF), a proangiogenic member of vascular endothelial growth family, is active during pathological conditions like cancer, metastasis formation and hind limb ischemia and in wound healing. Endothelial cells express PlGF and hypoxia positively modulates in vitro its expression. To verify whether hypoxia modulates PlGF expression in different cellular contexts and in vivo...
