Human fibroblast strains, 48BR, GMO73OA, and IBR/3 (from the MRC Cell Mutation Unit, Brighton, England), were obtained from skin biopsy of normal adult individuals aged 46 (female), 45 (female), and 33 (male), respectively. EK13 and EK4 fibroblasts were derived from foreskin explants in this laboratory(see below). Fibroblast cultures were grown in Earle's modified MEM (Gibco) supplemented with ...

Current models used in our laboratory to assess the migration and traction of a population of cells within biopolymer gels are extended to investigate temporal changes in these parameters during compaction of mechanically constrained gels. The random cell migration coefficient, micro (t) is calculated using a windowing technique by regressing the mean-squared displacement of cells tracked at hi...

The cultivation and characterization of a cell line derived from the foreskin of a fetal, rhesus monkey (rhfs2) are described. This cell line has proven satisfactory for isolation and assay of a variety of viral agents of human and simian origin. Virus titrations performed on foreskin cells yielded titers comparable to, or higher than, those obtained in rhesus monkey kidney cells (LLC-MK2). Rep...

Background The piwi family genes are highly conserved during evolution and play a crucial role in stem cell self-renewal, gametogenesis, and RNA interference in diverse organisms ranging from Arabidopsis to humans. Piwil2, also known as Hili, is one of the four human homologues of piwi. Piwil2 was found in germ cells of adult testis, suggesting that this gene functions in spermatogonial stem ce...

olea europaea l. commonly known as olive has been traditionally used for the prevention and treatment of many diseases since ancient times. olive has been reported to possess a broad spectrum of pharmacological properties. in the present study we investigated the activity of aqueous extract of olea europaea l. fruit at various concentrations on a2780, a172 and hfff2 cell lines proliferation by ...

Previous work has shown the importance of tumour-stroma interactions for prostate cancer development at the primary site. The aim of the present study was to find out whether evidence can be found for a tumour-stroma cross- talk also between metastatic prostate cancer cell lines and non-prostatic stromal fibroblasts which are encountered by metastatic cells at most sites. We addressed this issu...

aim: in this study, the effect of the essential oil of rosa damascena on human colon cancer cell line (sw742) and human fibroblast cells has been reported. background : colon cancer is the second lethal disease after lung cancer. owing to the existence of many side effects and problems related to common treatments such as surgery, chemotherapy and radiotherapy, better substitution is highly nee...

Orf virus has been utilized as a safe and efficient viral vector against not only diverse infectious diseases, but also against tumors. However, the nature of the genes triggered by the vector in human cells is poorly characterized. Using RNA sequencing technology, we compared specific changes in the transcriptomic profiles in human foreskin fibroblast cells following infection by the orf virus...

The genomes of HCMV clinical strains (e.g. FIX, TR, PH, etc) contain a 15 kb region that encodes 20 putative ORFs. The region, termed ULb', is lost after serial passage of virus in human foreskin fibroblast (HFF) cell culture. Compared to clinical strains, laboratory strains replicate faster and to higher titers of infectious virus. We made recombinant viruses with 22, 14, or 7 ORFs deleted fro...

A newly identified member of the tumor necrosis factor receptor (TNFR) superfamily shows activities associated with osteoclastogenesis inhibition and fibroblast proliferation. This new member, called TR1, was identified from a search of an expressed sequence tag database, and encodes 401 amino acids with a 21-residue signal sequence. Unlike other members of TNFR, TR1 does not contain a transmem...
