Cytotoxicity of depleted uranium, as a byproduct of military has been came to spotlight in recent decades. DU is known as a chemical rather than radioactive hazard and efforts to illustrating its mechanism is undergo, but the precise complete molecular mechanisms are still unclear. Recent studies showed that uranium induces biological changes in many different target tissues, such as the kid...

Background: This study was conducted to evaluate fibroblast co-culture and Activin A on in vitro maturation and fertilization of mouse preantral follicles. Methods: The ovaries from 12-14-day-old mice were dissected, and 120-150 μm preantral follicles were cultured individually in α-MEM as based medium for 12 days. A total number of 456 follicles were cultured in four conditions: (i) base mediu...

BACKGROUND Wound healing is a complex and dynamic process following damage in tissue structures. Due to extensive skin damage caused by burn injuries, this study determined the role of human adult peripheral and umbilical cord blood platelet-rich plasma on proliferation and migration in human skin fibroblasts. METHODS Platelet-rich plasma (5, 10, 15, 20 and 50% PRP) from human umbilica...

Objective(s): Umbilical cord blood is a good source of the mesenchymal stem cells that can be banked, expanded and used in regenerative medicine.  The objective of this study was to test whether amniotic membrane extract, as a rich source of growth factors such as basic-fibroblast growth factor, can promote the proliferation potential of the umbilical cord mesenchymal stem cells. Materials and ...

introduction: periodontal diseases are considered as some of the most common reasons of teeth loss, which occur due to the aggregation of microbial plaque and other precipitations on the dental surfaces . in this study, the scaling effect using manual tools, ultrasonic machine and erbium-doped yttrium aluminum garnet (er:yag)laser on the connection of the human gums connective tissue cells on t...

evaluation of autogenous fibrinogen extracted from horse blood in fibrin glue and it's effects on horse's fibroblast and keratinocyte cells were preformed. fibrinogen has been obtained by glycine precipitation technique from horse's blood. fibroblast cells were separated by explant culture method from neck skin and keratinocytes were separated by enzyme digestion from lib samples...

The aim of this study was to test if an extremely weak 1 GHz electromagnetic field (EMF), known to be in resonance with clusters of water molecules, has biological effects on human fibroblasts. We demonstrated that in an in vitro model of wound healing, this EMF can activate fibroblast migration. [(3)H]thymidine incorporation experiments demonstrated that the EMF could also activate fibroblast ...

Abstract Ethanol has a vast consumption around the world. Many researches confirmed some adverse effect of this component on human health. In addition, recent studies showed significant alteration in both cellular population, and protein profile of human foreskin fibroblast cell line (HFFF2) in the specific dosage of ethanol. Here, the role and interaction of some proteins (characterized by sig...
