Demonstration of dual rhinovirus infection in humans by isolation of different serotypes in human heteroploid (HeLa) and human diploid fibroblast cell cultures.

Mesenchymal Stem/Stromal-Like Cells from Diploid and Triploid Human Embryonic Stem Cells Display Different Gene Expression Profiles

Background: Human ESCs-MSCs open a new insight into future cell therapy applications, due to their unique characteristics, including immunomodulatory features, proliferation, and differentiation. Methods: Herein, hESCs-MSCs were characterized by IF technique with CD105 and FIBRONECTIN as markers and FIBRONECTIN, VIMENTIN, CD10, CD105, and CD14 genes using RT-PCR technique. FACS was performed fo...

Supportive Effects of Human Embryonic Fibroblast Cell Lines on Growth and Proliferation of EBV-Transformed Lymphoblastoid Cells

Human diploid fibroblast cells produce a spectrum of necessary growth factors and extracellular matrix (ECM) components essential for growth and proliferation of a variety of other cell types. In this study, the effect of five human embryonic fibroblast cell lines, isolated from liver, lung, skin and foreskin tissues, was investigated. A coculture system analyse was employed to cloning efficien...

Isolation of a monoclonal antibody that blocks attachment of the major group of human rhinoviruses.

Reciprocal competition binding assays have previously demonstrated that 20 of 24 human rhinovirus serotypes tested compete for a single cellular receptor. These studies suggested that the vast majority of rhinovirus serotypes utilize a single cellular receptor. With HeLa cells as an immunogen, a mouse monoclonal antibody was isolated which had the precise specificity predicted by the competitio...

The Isolation and Characterization a Human Diploid Cell Strain and Its Use in Production of Measles Vaccine

Growth and Isolation of Human Cytomegalovirus on a New Human Fetal Foreskin Fibroblast-derived Cell Line in Iran

Cell culture technique has been used for detection and confirmation of many different viruses in clinical samples. Although, new diagnostic methods have been developed for viral infections, traditional cell culturetechnique is still regarded as the “gold standard” for several infectious agents such as human cytomegalovirus(HCMV). In the present study, a new human fetal foreskin fibr...
