Objective(s): Cell therapy has provided clinical applications to the treatment of motor neuron diseases. The current obstacle in stem cell therapy is to direct differentiation of stem cells into neurons in the neurodegenerative disorders. Biomaterial scaffolds can improve cell differentiation and are widely used in translational medicine and tissue engineering. The aim...
سلول های اندوتلیال عروقی تحت تاثیر نیروهای مکانیکی حاصل از فشار و جریان خون هستند. آسیب سلولی می تواند باعث تغییر در عملکرد بیولوژیکی سلول های اندوتلیال و در نتیجه عوارض بالینی همانند آترواسکلروسیس گردد. محیط مکانیکی سلول های اندوتلیال عبارتنر از: تنش محیطی ناشی از فشار میانگین خون، کرنش سیکلی محیطی بر اثر پالس فشار خون و تنش برشی حاصل از جریان خون. سلول های اندوتلیال با مکانیزم های انطباقی و ب...
background and aims: influenza virus is a major pathogen involved in respiratory illnesses during winter seasons. a variety of diagnostic methods have been developed to identify influenza viruses in clinical specimen. methods: nasal and pharyngeal samples taken from patients were inoculated into madin-darby canine kidney (mock) cells and embryonated chicken eggs (eces). the culture media was as...
background: sertoli cells play a pivotal role in creating microenvironments essential for spermatogonial stem cells (sscs) self-renewal and commitment to differentiation. maintenance of sscs and or induction of in vitro spermiogenesis may provide a therapeutic strategy to treat male infertility. objective: this study investigated the role of luekemia inhibitory factor (lif) on the propagation o...

two different growth media, namely complex and defined media, were used to examine establishment of steady-state conditions in phosphate-limited culture system of saccharomyces cerevisiae cen.pk113-5d strain. using the defined growth medium, it was possible to obtain steady state condition in the continuous culture. the effect of phosphate concentration on the growth of s. cerevisiae in phospha...
we aimed to develop a cost-effective and robust method to predict drug resistance in individualpatients. representative tissue fragments were obtained from tumors removed from femalepatients, aged 24-74 years old. the tumor tissue was taken by a histopathology’s or a surgeonunder sterile conditions. cells obtained by enzymatic dissociation from tumor after surgery, werecultured as a monolayer f...
Background and Aims: Adventitious agents, especially viral agents are among the most important concerns in viral vaccines. Viral contamination of biological products may arise from the original source of the reagents such as, serum, trypsin, animal or human derived media components or cell culture and working seed or cross contamination of vaccine during production. In this study, adventitious ...
