0918 - Gene Expression in Chondrogenesis during Fracture Healing and the Effect of Basic Fibroblast Growth Factor
ثبت نشده
چکیده
Introduction: Chondrogenesis occurring in soft callus is one of the major histological processes in the healing of fractures, though the molecular and cellular events, which regulate this process, have not been fully elucidated. In the present study, using a standardized rat closed fracture model, we examined the spatial and temporal gene expression for cartilage-related proteins and extensively characterized the chondrogenesis during fracture healing. In addition, we percutaneously injected bFGF into the fracture site and analyzed the effect of exogenous bFGF on the chondrogenesis.

The gene encoding the human basic fibroblast growth factor (hbFGF) has been already chemically-synthesized and cloned in pET-3a expression vector (Pasteur Institute of Iran). In the present study, we compared the level of expression of this synthetic hbFGF and its related cDNA in Escherichia coli. The pBR322-cDNA of hbFGF supplied by Dr. Seno (from Molecular Biology Dept, Okaido prefectural uni...

Abstract Background and purpose: Delayed wound healing is a common complication of diabetes mellitus. However, less is known about the cause of this pathology. Types of skin cells, extracellular matrix and variety of growth factors are involved in wound healing. The use of recombinant growth factors in researches and production of skin substitutes are still a challenge. Much research has bee...
متن کاملEffect of Basic Fibroblast Growth Factor on Achilles Tendon Healing in Rabbit
BACKGROUND Tendon injuries are common and it takes a long time for an injured tendon to heal. Adverse phenomena such as adhesion and rupture are associated with these injuries. Finding a method to reduce the time required for healing whichimproves the final outcome, will lead to decreased frequency and intensity of adverse consequences. This study was designed to investigate the effects ...

Objective(s): This study aimed to determine the collagen type II (COL2) and SOX9 expression in interleukin growth factor (IGF-1)-induced Wharton’s Jelly mesenchymal stem cells (WJMSCs) and the level of chondrogenic markers in co-culture IGF1-WJMSCs and IL1β-CHON002 as osteoarthritis (OA) cells model. Materials and Methods: WJMSCs were induced with IGF1 (75, 150, and 300 ng/ml) to enhance their ...

Background & Aims: Neurotrophic and growth factors are known to have positive effects on neuronal proliferation. However, findings on the effects of exercise training on these factors following brain stroke are limited. Thus, the aim of the present study was to investigate the effect of endurance training on gene expression of nerve growth factor (NGF) and fibroblast growth factor (FGF) in the ...
