conclusions our underlying hypothesis is that recapitulating the three-dimensional early embryonic structure, in order to reproduce better in vitro the three-dimensional morphogenetic-like re-arrangements, would improve cells differentiation, when in vivo transplanted; moreover, it could be used as a simplified cancer disease model and reliable drug evaluation method as well. results the proces...
conclusions our data suggest that preconditioning with 5 μm h2o2 + 0.5% fbs and 10 μm h2o2 + 5% fbs improved cell proliferation and viability. however, the mechanisms related to protective properties of preconditioning and using this strategy in stem cell therapy requires more research. background mesenchymal stem cells (mscs) survival decreased following in vivo injection and its application h...
background: due to increasing clinical demand for adipose tissue, a suitable cell for reconstructive adipose tissue constructs is needed. in this study, we investigated the ability of human endometrial-derived stem cells (enscs) as a new source of mesenchymal stem cells to differentiate into adipocytes. enscs are the abundant and easy available source with no immunological response, for cell re...
background: fusion of dendritic cells (dcs) with melanoma cells could reinforce the antigenicity of tumors as a strategy for the treatment of malignant melanoma. however, the insufficient quantity of dcs and the low fusion efficiency limits the development of such approach. objective: to define the dosage of the stimulating factors as well as the induction condition for the optimal dcs preparat...
background: endometriosis is a complex estrogen-dependent disease that is defined as the presence of endometrial gland and stroma outside the uterine cavity. although the exact mechanism for the development of endometriosis remains unclear, there is a large body of research data and circumstantial evidence that suggests a crucial role of estrogen in the establishment and maintenance of this dis...
بر اساس تجربیات انتقال دیستال اولنا یک روش خوب ترمیم بعد از اکسیزیون دیستال رادیوس بویژه در بیماران مبتلا به giant cell tumor می باشد. در این روش عود و عوارض بعد از عمل بسیار ناچیز بوده و حرکات دست در حد قابل قبولی برای بیمار حفظ می شود ولی قدرت عضلات از نوع grip دست عمل شده در حدود 75 - 50 درصد کاهش می یابد. مشکل بیمار بیشتر بعد از عمل می باشد زیرا به مدت 6 ماه باید دست داخل گچ باشد و مدت 6 ما...
پیل سوختی میکروبی(mfc) شکل جدیدی از انرژی تجدید پذیر است.دراین پیل ها مواد آلی به عنوان سوخت مصرف می شوند وباازتجزیه مواد آلی توسط باکتریها انرژی الکتریکی تولید می شود.فاضلاب وپساب نیز می توانند به عنوان سوخت درپیل مصرف شوند وضمن تولید انرژی الکتریکی پساب نیز تصفیه می شود. در این تحقیق روند تولید انرژی وتصفیه شدن پساب با بررسی جریان،مقاومت ، ولتاژ پیل وآنالیز cod,tds,ec الکترولیت بررسی می شود. ...
the aim of this work was to see whether tamarin immunisation with recombinant vaccinia virus expressing epstein barr virus latent proteins could prime t cells which were, on activation, able to inhibit the outgrowth of epstein barr virus transformed cells in vitro. the vaccination appeared to be successful as all vaccinated tamarins developed vaccinia lesions. however, the vaccination protocol ...
background: the rh antigens are expressed as parts of a protein complex in the rbc membrane. this complex is a tetramer, consisting of two molecules of rhag and two molecules of rh proteins. to express rhd in rbc membrane, expression of rhag is essential. this co-expression only occurs in the erythroid lineage. k562 cell line has an erythroid lineage. materials and methods: cord blood was used ...
objective(s):mesenchymal stem cells (mscs) derived from wharton’s jelly (wj-mscs) are now much more appealing for cell-based infertility therapy. hence, wj-mscs differentiation toward germ layer cells for cell therapy purposes is currently under intensive study. materials and methods: mscs were isolated from human wharton’s jelly and treated with bmp4, retinoic acid (ra) or co-cultured on human...
