Studies of Growth Factors of Embryo Extract
نویسندگان
چکیده
1. Survival of cells without cell proliferation. 2. Cell multiplication without increase in protoplasmic matter, due to the presence of substances stimulating mitosis and the absence of the proper nutritive elements in the culture medium. 3. Proliferation of cells with new formation of protoplasmic matter through utilization of nutritive substances contained in t,he culture medium under conditions which allow either (a) a restricted continuation of life and growth or (b ) an unlimited continuation of life and growth.

Evaluation the effects of Teucrium polium hydroalcoholic extract on the fetus and chorioallantoic fluid using a chick embryo model
Introduction Side effects of drugs have always been controversial issues in medical science. To date, sufficient researches were not performed on the side and pathological effects of Teucrium polium as an herb in the fetus. Therefore, the present study aimed to investigate the pathological effects of Teucrium polium hydroalcoholic extract on chorioallantoic fluid composition, weight, growth, e...
متن کاملThe in vitro effect of chick embryo extract on mice pre-antral follicles
Chick embryo extract (CEE) contains a variety of growth factors which may improve in vitro follicle growth. Therefore, the effect of CEE on mouse pre-antral follicle culture was evaluated. Different percentages of CEE (0, 0.50%, 1.00%, 5.00% and 10.00%) were added to culture medium. Hence, the osmolarity of media was measured. Pre-antral follicles with diameter of 120-150 μm were isola...
متن کاملI-40: Implantation Failure
Background: The process of implantation involves the interaction of the human embryo and the uterine epithelium. Failure of implantation is a major reason for infertility in women and the inability to achieve endometrial receptivity is responsible for much of the failure of reproductive technologies. Management of repeated implantation failure despite transfer of good-quality embryos still rema...
متن کاملEvaluation of of the performance of the zebrafish (Danio rerio) model in nanotoxicology studies with emphasis on embryo pathology
The present study was conducted to evaluate the performance of zebrafish (Danio rerio) as a model in embryo and fetal pathology in nanotoxicology studies. Examination of the sources showed that it is possible to completely inhibit hatching and fetal death when exposed to nanoparticles, because nanoparticles interact with hatching enzymes. Zebrafish embryo developmental abnormalities have been s...
متن کاملImproved viability of random pattern skin flaps with the use of bone marrow mesenchymal-derived stem cells and chicken embryo extract
Objective(s): Covering tissue defects using skin flaps is a basic surgical strategy for plastic and reconstructive surgery. The aim of this study was to evaluate the effects of chicken embryo extract (CEE) and bone marrow derived mesenchymal stem cells (BM-MSCs) on random skin flap survival (RSF) in rats. Using chicken embryo extract can be an ideal environment for the growth and proliferation ...
