Herein, we show that TNF exerts a pH-dependent increase in membrane conductance in primary lung microvascular endothelial cells and peritoneal macrophages. This effect was TNF receptor-independent, since it also occurred in cells isolated from mice deficie ...
In this thesis, a new microfabricated flow cytometer for single cell discrimination based on dielectric spectroscopy is presented. Integrated tools for rapid in-flow cell handling are also demonstrated. Signal amplification and analysis as well as the chip ...
PURPOSE: To investigate the potential use of polymeric nanoparticles for the delivery of antisense oligonucleotides in HIV-1-infected cell cultures. METHODS: Phosphorothioate oligonucleotides were encapsulated into poly (D,L-lactic acid) nanoparticles. Two ...
Exogenous growth factors normally required in cell culture activate cell proliferation via the mol. controls of cell-cycle progression. Highly differing influences of mitogenic stimulation of Chinese hamster ovary (CHO) cells by insulin and basic fibroblas ...
To overcome ammonia inhibition in animal cell culture, a method utilizing porous polytetrafluoroethylene membranes with an assocd. pH gradient was investigated. Model expts. without cells were carried out in three different reactor configurations suitable ...
The chromosomal locations, amounts, and level of expression of transfected, amplified c-myc and dihydrofolate reductase sequences were measured in cells cultured in the presence and absence of methotrexate. These studies show that the location and amount o ...
A new cytological tool, based on the micro Coulter particle counter (CPC) principle, aimed at diagnostic applications for cell counting and separation in haematology, oncology or toxicology is described. The device measures the spectral impedance of indivi ...
In order to investigate cell-specific differences in the response of in vitro models to environmental toxicants, we compared the capacity of nine polycyclic aromatic hydrocarbons (PAHs) to induce cytochrome P4501A (CYP1A) in primary rainbow trout (Oncorhyn ...

Culturing and comparing the discrete stages of tumorigenesis provide a route to defining important components of the cancer phenotype and, in addition, present the opportunity to establish cell cultures more representative of normal cells than the ultimate ...
Bone is a natural composite construct, with a gradient structure going from a loose interconnected cellular core to an outer dense wall, thus minimizing bone weight while keeping a high mechanical resistance. Due to this unique and complex structure, bone ...
