Growth Factors Release From Concentrated Growth Factors: Effect of β-Tricalcium Phosphate Addition

Journal of Craniofacial Surgery, 2018
Background:Platelet concentrates represent a new approach to improve tissue regeneration and can be used alone or together with autogenous bone, recombinant human growth factors, and/or other biomaterials, to enhance tissue regeneration. Among platelet concentrates, concentrated growth factors (CGFs) exhibit an interesting clinical and biotechnological

Growth factors, CD34 positive cells, and fibrin network analysis in concentrated growth factors fraction

Microscopy Research and Technique, 2011
AbstractAn interesting clinical option for optimizing healing tissue is the use of platelet concentrate. Platelets contain high quantities of growth factors, among these TGF‐β1 and VEGF, which are known to be implicated in tissue regeneration. CGF is produced by processing blood samples with a special centrifuge device; three layers are formed: top ...

Serum concentrations of epidermal growth factor in human pregnancy

American Journal of Obstetrics and Gynecology, 1973
Abstract A newly measurable peptide, epidermal growth factor (EGF), has been found in pregnant women with the use of a tube radioimmunoassay technique. This peptide appeared to have its highest concentrations during the early part of pregnancy, but measurable quantities were found in the serum throughout the entire course of the gestational period ...

Hepatocyte Growth Factor, Epidermal Growth Factor, and Placenta Growth Factor Concentrations in Peripheral Blood of Pregnant Women With Alcohol Abuse

Alcoholism: Clinical and Experimental Research, 2002
Background: Alcohol abuse during pregnancy compromises fetal development not only directly but also by abnormal placental function. Therefore, hepatocyte growth factor (HGF), epidermal growth factor (EGF), and placenta growth factor (PlGF), expressed in the placenta, may play a role in alcohol‐induced placental dysfunction.Methods: Peripheral venous ...

Vascular Endothelial Growth Factor Serum Concentrations in Ovarian Cancer

Obstetrics & Gynecology, 1998
To determine whether serum vascular endothelial growth factor is an independent prognostic factor in ovarian cancer patients.We measured vascular endothelial growth factor in pretreatment serum samples of 60 women with International Federation of Gynecology and Obstetrics stages I to IV epithelial ovarian cancer, using an enzyme-linked immunosorbent ...

Transforming growth factor‐β1 serum concentration

British Journal of Urology, 1998
Objective  To assess serum levels of transforming growth factor‐β1 (TGF‐β1), normally markedly elevated in prostate cancer tissue, in patients with cancer of the prostate, and to correlate these levels with tumour stage and serum prostate specific antigen (PSA) levels.

The role of concentrated growth factor on implant stability: A preliminary study

Journal of Stomatology, Oral and Maxillofacial Surgery, 2020
The purpose of this preliminary study was to evaluate the effect of concentrated growth factor (CGF) on dental implant stability in type 2 bone using the resonance frequency analysis (RFA) device Smartpeg®.The researchers carried out a prospective cohort study on a sample group composed of 12 patients (mean age=67) who required dental implants. Implant

Growth Factors Release in Concentrated Growth Factor and Advanced Platelet‐Rich Fibrin Sticky Bone

Oral Diseases
ABSTRACTObjectiveSticky bone, created from concentrated growth factor (CGF) or advanced platelet‐rich fibrin (A‐PRF), contains various growth factors. This study analyzed the release patterns of growth factors from CGF sticky bone (CGF‐SB) and A‐PRF sticky bone (A‐PRF‐SB) to inform their application in bone grafting.MethodsCGF, A‐PRF, CGF‐SB, and A‐PRF‐

Impact of laparotomy and liver resection on the peritoneal concentrations of fibroblast growth factor 2, vascular endothelial growth factor and hepatocyte growth factor

Journal of Cancer Research and Clinical Oncology, 2005
Some data have suggested that major surgery is associated with the post-operative growth of residual tumour masses but the mechanism of this is unknown. This study was designed to determine the relationship between intraperitoneal (IP) cytokine levels, and laparotomy in benign and malignant settings.Intraperitoneal fluid specimens were obtained at the ...

Factors influencing tissue concentration of vascular endothelial growth factor in colorectal carcinoma

The American Journal of Gastroenterology, 2000
Vascular endothelial growth factor (VEGF) promotes proliferation of various tumor cells by stimulating angiogenesis. Experimentally, hypoxia and energy depletion are known to induce angiogenesis by increasing VEGF expression. We investigated whether factors reflecting the general condition of the patients influence the tissue concentration of VEGF in ...
