Abstract Background: Choroid plexus (CP) is a branched structure made up of a single layer of epithelial cells and blood capillaries, forming the blood-CSF-barrier. The CSF (cerebrospinal fluid) is mainly produced from the CP. Aquaporin1 (AQP1), water channels that are highly expressed on the apical side of the membrane in choroid plexus, have a major role in mediating water transport across th...
Purpose: The objective for this study is to investigate the morphology and ultrastructure of mouse endometrial epithelial cell monolayer cultured on matrigel in dual-chambered system as an in vitro mouse endometrial epithelial cell culture model that mimics structural and functional properties of the endometrial epithelium in vivo. Materials and Methods: Mouse endometrial epithelial cells were...
Hepatic and renal electron microscopic investigations were carried out in 10 chickens that had experimental intraduodenal infection with Clostridium perfringens Type A. Fourteen days postinfection, there were ultrastructural changes in hepatocytes and renal tubular epithelial cells; these included mitochondrial lesions (swelling, cristolysis, rarefication of the matrix, myelin figures), glycoge...
Spontaneous Mesenchymal to Epithelial Like Tissue Transition (MET) in a Long Term Human Skin Culture
In an attempt to isolate multipotent stem cells from foreskin in a long-term culture, we encountered an interesting phenomenon which was the conversion of the fibroblast dominant condition to epithelial-like tissue formation. However, the basic mechanism(s) which may be involved in this conversion is not clear. This study was designed to evaluate the cells protein secretion activity and examine...
چکیده مقدمه: ماده خارج سلولی به عنوان بخش مهم ریز محیط microenvironment) (، نقش اساسی در نگهداری وضعیت تمایز دارد. در بررسی های گذشته، این اثر در برخی سلول ها از جمله سلول های پوششی لوله رحم و یا رحم مطالعه شده است. در این پژوهش ها ، برای حفظ تمایز سلول ، علاوه بر ماده خارج سلولی عوامل دیگر ی مانند هورمون ها، فاکتورهای رشد و سلول های داربستی نیز بکار رفته است ولی فراساختار سلول های کشت داده شده...
Necturus gallbladder epithelial cells bathed in 10 mM HCO3/1% CO2 display sizable basolateral membrane conductances for Cl- (GClb) and K+ (GKb). Lowering the osmolality of the apical bathing solution hyperpolarized both apical and basolateral membranes and increased the K+/Cl- selectivity of the basolateral membrane. Hyperosmotic solutions had the opposite effects. Intracellular free-calcium co...
Background: In apoptosis is physiological cell death which eliminates injured and old cells. Any disruption in apoptosis, leads to disease. Resveratrol is a natural polyphenol with estrogen-like, antioxidant and antiinflammatory properties; also it showed cell prolifratory and inhibitory effect. The aim of present study was to determine resveratrol effect on apoptosis of human endometrial epith...
The human amniotic membrane known as the innermost single epithelial-covered layer provides many applications such as applicable anti-inflammatory and anti-cancer effects. These immunomodulatory effects belongs to the epithelial cells, a type of epiblast-derived fetal stem cells which currently used for regenerative medicine and transplantation. These cells are collected by author-prepared faci...
Background: Radiotherapy is an effective and important therapeutic method for breast cancer, but at the same time it has a radiation-induced bystander effect on normal tissue around the tumor. Repair of double-strand breaks (DSBs) by normal cells can reduce the extent of damage caused by this effect. Caveolin-1 (Cav-1) is an important regulatory molecule in cell signal transduction. However, th...
