Conditional mutagenesis is a powerful tool to analyze gene functions in mammalian cells. The site-specific recombinase Cre can be used to recombine loxP-modified alleles under temporal and spatial control. However, the efficient delivery of biologically active Cre recombinase to living cells represents a limiting factor. In this study we compared the potential of a hydrophobic peptide modified ...
Studies of human and murine bone marrow explants have demonstrated the existence of stromal cell precursors that give rise to colonies of adherent cells in short-term cultures. Because previous data suggested that these colonies were composed of fibroblasts, the precursor cells were termed fibroblast colony-forming units (CFU-F). However, we have recently shown that the stromal cells which supp...
The cyclin D1 gene encodes the regulatory subunit of a holoenzyme that drives cell autonomous cell cycle progression and proliferation. Herein we show cyclin D1 abundance is increased >30-fold in the stromal fibroblasts of patients with invasive breast cancer, associated with poor outcome. Cyclin D1 transformed hTERT human fibroblast to a cancer-associated fibroblast phenotype. Stromal fibrobla...
KB cells from a human nasopharyngeal tumor were cocultivated with human embryonic fibroblasts (HF 8101 cells); 7 to 14 days after incubation, "spongy degeneration"-like changes developed in the target cell-growing area. These changes developed in other target cells [HeLa cells from human cervical cancer, human hepatoma cells (PLC/PRF/5), and human amnion FL cells] cocultured with several kinds ...
The rates of conversion of types I and III procollagens to their respective collagens were compared in seven fibroblast culture systems of murine or human origin. During 24 hr of radioactive labeling or after shorter pulses followed by chases of 20-48 hr, no evidence was obtained for conversion of radiolabeled type III procollagen to insoluble collagen. In the same cultures and under the same c...
in order to adapt lasota strain of newcastle disease virus (ndv) on chick embryo fibroblast (cef) cells, 0.1 ml from lasota vaccine produced in razi vaccine and serum research institute inoculated to the cef cells and was passaged five times in the cef grown in eagle’s minimum essential medium (mem). first to third passages were blind but in fourth passage cytopathic effect of virus was observe...
fibroblasts could be considered as connective tissue cells that are morphologically heterogeneous with diverse functions depending on their location and activity. these cells play critical role in health and disease such as cancer and wound by production of collagen, fibronectin, cytokines and growth factors. absence of insulin and other growth factors in serum deprivation condition and similar...
Background Persistently activated fibroblasts status leads to progressive extracellular matrix (ECM) deposition and tissue remodeling. The hallmark of systemic sclerosis (SSc) is collagen accumulation in organs, mainly skin lung. Despite intensive progress understanding disease occurence, SSc remains an intriguing with unknown pathology high mortality. Sorbin SH3 domain-containing protein2, enc...
