TLDR
Findings show that flt encodes a receptor for VEGF-VPF, a factor that induces vascular permeability when injected in the guinea pig skin and stimulates endothelial cell proliferation.Abstract:
The fms-like tyrosine kinase (Flt) is a transmembrane receptor in the tyrosine kinase family. Expression of flt complementary DNA in COS cells conferred specific, high-affinity binding of vascular endothelial growth factor, also known as vascular permeability factor (VEGF-VPF), a factor that induces vascular permeability when injected in the guinea pig skin and stimulates endothelial cell proliferation. Expression of Flt in Xenopus laevis oocytes caused the oocytes to release calcium in response to VEGF-VPF. These findings show that flt encodes a receptor for VEGF-VPF.read more

The biology of VEGF and its receptors.
TL;DR: Vascular endothelial growth factor (VEGF) is a key regulator of physiological angiogenesis during embryogenesis, skeletal growth and reproductive functions and is implicated in pathologicalAngiogenesis associated with tumors, intraocular neovascular disorders and other conditions.

TL;DR: It is suggested that EC progenitors may be useful for augmenting collateral vessel growth to ischemic tissues (therapeutic angiogenesis) and for delivering anti- or pro-angiogenic agents, respectively, to sites of pathologic or utilitarianAngiogenesis.

The biology of vascular endothelial growth factor
TL;DR: The establishment of a vascular supply is required for organ development and differentiation as well as for tissue repair and reproductive functions in the adult.

TL;DR: It is reported that formation of blood vessels was abnormal, but not abolished, in heterozygous VEGF-deficient (VEGF+/-) embryos, generated by aggregation of embryonic stem (ES) cells with tetraploid embryos (T-ES)16,17, and even more impaired in homozygous D1-VEGF- deficient (VDGF-/-) T-ES embryos, resulting in death at mid-gestation.

Vascular Endothelial Growth Factor in Ocular Fluid of Patients with Diabetic Retinopathy and Other Retinal Disorders
Lloyd Paul Aiello,Robert L. Avery,Paul G. Arrigg,B A Keyt,Henry D. Jampel,Sweta Shah,Louis R. Pasquale,Hagen Thieme,Mami Iwamoto,John Edward Park +9 more
TL;DR: The data suggest that VEGF plays a major part in mediating active intraocular neovascularization in patients with ischemic retinal diseases, such as diabetic retinopathy and retinal-vein occlusion.

Vascular endothelial growth factor is a secreted angiogenic mitogen
TL;DR: DNA sequencing suggests the existence of several molecular species of VEGF, a heparin-binding growth factor specific for vascular endothelial cells that is able to induce angiogenesis in vivo.

TL;DR: Tumor ascites fluids from guinea pigs, hamsters, and mice contain activity that rapidly increases microvascular permeability, and this activity is secreted by these tumor cells and a variety of other tumor cell lines in vitro.

Pituitary follicular cells secrete a novel heparin-binding growth factor specific for vascular endothelial cells
TL;DR: A growth factor for vascular endothelial cells identified in the media conditioned by bovine pituitary follicular cells and purified to homogeneity by a combination of ammonium sulfate precipitation, heparin-sepharose affinity chromatography and two reversed phase HPLC steps is proposed to be named VGF on the basis of its apparent target cell selectivity.

TL;DR: The cDNA sequence of VPF from human U937 cells was shown to code for a 189-amino acid polypeptide that is similar in structure to the B chain of platelet-derived growth factor (PD GF-B) and other PDGF-B-related proteins, suggesting that VPF appears to be related to the PDGF/v-sis family of proteins.
