Embryonic stem (ES) cells derived from mammalian embryos have the ability to form any terminally differentiated cell of the body. We herein describe production of parthenogenetic buffalo (Bubalus Bubalis) blastocysts and subsequent isolation of an ES cell line. Established parthenogenetic ES (PGES) cells exhibited diploid karyotype and high telomerase activity. PGES cells showed remarkable long...
OBJECTIVE We demonstrated previously that mouse embryonic stem (ES) cell-derived vascular endothelial growth factor receptor-2 (VEGF-R2)-positive cells can differentiate into both vascular endothelial cells and mural cells. This time, we investigated kinetics of differentiation of human ES cells to vascular cells and examined their potential as a source for vascular regeneration. METHODS AND ...
5T4 oncotrophoblast antigen is a transmembrane glycoprotein expressed by trophoblast and many carcinomas but not most normal adult tissues. Results from overexpression of human and mouse 5T4 cDNA in cell lines are consistent with it having an influence on adhesion, shape and motility. We show that murine embryonic stem cell lines are 5T4 negative but that there is rapid up regulation of protein...
Lambs respond to vaccination against bacteria and viruses but have a poor immunological response to nematodes. Here we report that they are protected against the parasitic nematode Haemonchus contortus after vaccination with excretory/secretory (ES) glycoproteins using Alhydrogel as an adjuvant. Lambs immunized with ES in Alhydrogel and challenged with 300 L3 larvae/kg body weight had a reducti...
fasciolosis is a disease caused by liver fluck of the genus of fasciola. diagnosis of fasciolosis has been challenging for a long period due to low sensitivity of the coprological diagnostic method. in this study, an in-house dot-elisa method; using excretion–secretory (es ag) and crude (cr ag) antigens of fasciola was described for diagnosis of fasciolosis in cattle. for this purpose, the sera...
Ewing sarcoma (ES)/primitive neuroectodermal tumor (PNET) is a malignant small round blue cell neoplasm of presumed neuroectodermal origin that affects bones and soft tissue in children and young adults. Nearly 80% of the patients are younger than 20 years. The tumor cells characteristically express CD99 (MIC2 antigen), a glycoprotein localized on cell membrane. The defining feature of ES/PNET ...
Embryonic stem (ES) cells are pluripotent stem cells derived from the inner cell mass of the blastocyst. ES cell surface molecules are important for the identification, labeling, sorting, quality control and functional studies of ES cells. Currently, knowledge of ES surface molecules is limited. To identify new surface molecules, we generated a panel of rabbit monoclonal antibodies (rMabs) agai...
It was reported that M1 monoclonal antibody (M1 mab) inhibited hamster sperm-egg fusion in a dose-dependent manner. The antigen was localized to the equatorial segment (ES) of the hamster sperm, and that after the acrosome reaction, it was exposed on the surface of the sperm plasma membrane overlying the ES. The M1 antigen therefore fulfilled the main requirements of a sperm component that migh...
برای تعیین معادله حالت ism یک دمای کاهش یافته جدید مقیاسی t*es t*es(t,es,pf) پایه گذاری کرده ایم، که دمای مطلق، e و pf به ترتیب انرژی سطح و دانسیته مایع در دمای انجماد می باشند. ضریب دوم ویریال کاهش یافته b*2 که با استفاده از یک رابطه همبستگی حالات متناظر برای دسته ای از هیدروکربن های کروی، خطی و زنجیربلند قابل محاسبه است . روش ارائه شده در این پایان نامه برتریهایی نسبت به روشهای قبلی دارد.
The identification of a large number of antigens with potential for development of new tuberculosis vaccine has been accomplished in recent years. This study was designed for cloning and expression of ESAT-6 as a potent antigen of Mycobacterium tuberculosis. Selected gene (Rv3875) was amplified by PCR and product was ligated into expressing plasmid vector pQE30 and recombinant pQE30-ES plasmi...
