Ulcert Repair by Spray of Epithelial Stem Cells
Purpose: Separation, prolifration of stem cells and repairing of injured parts using these cells. Materials and Methods: This was a Lab-Experimental study. We used 6 male albino rabbits. At first, under general anesthesia 5x5 cm2 full thickness skin from one of the rabbits separated, washed using 70% alcohol and inserted in cold HBSS. Then it was cut into 4-6 mm pieces, washed again and incubat...
متن کاملGastric stem cells and gastric cancer stem cells
The gastric epithelium is continuously regenerated by gastric stem cells, which give rise to various kinds of daughter cells, including parietal cells, chief cells, surface mucous cells, mucous neck cells, and enteroendocrine cells. The self-renewal and differentiation of gastric stem cells need delicate regulation to maintain the normal physiology of the stomach. Recently, it was hypothesized ...
متن کاملEffect of Transforming Growth Factor-β (TGF-β) on proliferation of gastric epithelial cells in culture
Objective: Helicobacter pylori has a well-established role in the development of gastric cancer. In vitro studies reveal increased proliferation of the gastric mucosa in the presence of H. pylori infection. It has been also shown that production of some cytokines, such as interleukin-1 beta (IL-1b) is in...

چکیده مقدمه: ماده خارج سلولی به عنوان بخش مهم ریز محیطMicroenvironment)(، نقش اساسی در نگهداری وضعیت تمایز دارد. در بررسی‌های گذشته، این اثر در برخی سلول‌ها از جمله سلول‌های پوششی لوله رحم و یا رحم مطالعه شده است. در این پژوهش‌ها، برای حفظ تمایز سلول ، علاوه بر ماده خارج سلولی عوامل دیگر‌ی مانند هورمون‌ها، فاکتورهای رشد و سلول‌های داربستی نیز بکار رفته است ولی فر...
متن کاملEpithelial stem cells in vivo.
Cellular topography within the highly polarized surface epithelia can be used to identify the location of the stem cells. In some instances, this can be quite precise and allows the characteristics of stem cells to be studied. Our current knowledge of the stem cell population in murine epidermis and small intestinal crypts is reviewed. In the epidermis, the stem cells would appear to make up ab...
