Vascular endothelial growth factor is expressed in rat corpus luteum
TLDR
The results demonstrate the expression of VEGF in the CL but not in mural granulosa cells, suggesting a temporal relation between V EGF expression and growth of capillary vessels, and suggest that VegF is involved in the process of CL angiogenesis.Abstract:
In the course of the development of the ovarian follicle and differentiation of granulosa cells into corpus luteum (CL), extensive changes in the microvasculature of these structures take place. This suggests the local release of angiogenic factors. In the present work we examined whether a newly described secreted vascular endothelial growth factor (VEGF) is expressed in normal rat ovary by in situ hybridization. Our results demonstrate the expression of VEGF in the CL but not in mural granulosa cells, suggesting a temporal relation between VEGF expression and growth of capillary vessels. The hybridization pattern in the CL was consistent with localization of VEGF message to luteal cells. Expression of VEGF was detected also in cumulus oophorus cells. These findings suggest that VEGF is involved in the process of CL angiogenesis.read more

Vascular endothelial growth factor: basic science and clinical progress.
TL;DR: Vascular endothelial growth factor (VEGF) is an endothelial cell-specific mitogen in vitro and an angiogenic inducer in a variety of in vivo models and is implicated in intraocular neovascularization associated with diabetic retinopathy and age-related macular degeneration.

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: 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.

TL;DR: As expected from their structural relationship, both FGF and aFGF interact with the same receptor (7), thereby having similar, if not identical, properties.

TL;DR: An oligonucleotide probe was designed from the nucleotide sequence of the amino-terminal exon of bovine acidic FGF, taking into account the 55 percent amino acid sequence homology between the two factors.
