helicobacter pylori was the main cause of gastric cancer (gc) in all over the world that results in intestinal- and diffuse-type carcinoma. infection by this bacterium remains chronic for a long time. in vitro studies have highlighted the role of stem cells in gc. h. pylori infection results in tissue injury and the adult/tissue stem cells subsequently start to replace the dead cells. the genet...
هدف: کشت سلول های اسپرماتوگونی و تولید سلول های پر توان embryonic stem cells (es like cells) که دارای قابلیت بازسازی و تولید هرسه نوع لایه زایای جنینی می باشند، این سلول ها را به عنوان منبع کافی و جدیدی برای سلول درمانی و ترمیم در بیماریها از جمله بیماریهای نورودژنراتیو پیشنهاد می دهد. در تحقیق حاضر تمایز سلول های اسپرماتوگونی موش به سلول های شبه الیگودندروسیت و نقش آنها درمیلین سازی پس از پیون...
INTRODUCTION Many antitumor therapies induce apoptotic cell death in order to cause tumor regression. Paradoxically, apoptotic cells are also known to promote wound healing, cell proliferation, and tumor cell repopulation in multicellular organisms. We aimed to characterize the nature of the regenerative signals concentrated in the micromilieu of dead and dying cells. METHODS Cultures of viab...
PURPOSE To evaluate the La autoantigen as a target for specific monoclonal antibody (mAb) binding in dead cancer cells after use of DNA-damaging chemotherapy. EXPERIMENTAL DESIGN In vitro studies of La-specific 3B9 mAb binding to malignant and normal primary cells with and without cytotoxic drug treatment were done using immunoblotting and flow cytometry. Chromatin-binding studies and immunof...
The human body loses several billions of cells daily. When cells die in vivo, the corpse of each dead cell is immediately cleared. Specifically, dead cells are efficiently recognized and cleared by multiple types of neighboring phagocytes. Early research on cell death focused more on molecular mechanisms of cell death regulation while the cellular corpses were merely considered cellular debris....
We used two-channel three-dimensional time-lapse fluorescence confocal imaging in live rat hippocampal slice cultures (1-7 days in vitro) to determine the motility behaviors of activated microglia as they engage dead and dying cells following traumatic brain tissue injury. Live microglia were labeled with a fluorescently conjugated lectin (IB(4)), and dead neurons were labeled with a membrane-i...
