HeLa cells are used to study the life cycles of many different viruses, including the human rhinoviruses (HRV) in the family Picornaviridae. Although the natural targets of HRV are human bronchial epithelial cells (hBE), it is generally more difficult to obtain and maintain the relevant primary cell cultures, relative to HeLa cells. Given that the HRV are now identified as a major cause of huma...
Human immunodeficiency virus 1 (HIV-1) infects T cells, macrophages and dendritic cells and can manipulate their cytoskeleton structures at multiple steps during its replication cycle. Based on pharmacological and genetic targeting of cytoskeleton modulators, new imaging approaches and primary cell culture models, important roles for actin and microtubules during entry and cell-to-cell transfer...
Parietal epithelial cells (PECs) are crucially involved in the pathogenesis of rapidly progressive glomerulonephritis (RPGN) as well as in focal and segmental glomerulosclerosis (FSGS). In this study, transgenic mouse lines were used to isolate pure, genetically tagged primary cultures of PECs or podocytes using FACsorting. By this approach, the morphology of primary glomerular epithelial cells...
scribe techniques for dissociating rat liver and isolating a high yield of viable hepatocytes for initiation of monolayer cultures representative of the hepatic parenchyma. The properties of hepatocyte cultures were studied and factors affecting their quality were examined. [The 5Cl~indicates that this paper and the three others in the series have been cited(individually or in some combination)...
The conditions for growing preneoplastic mammary epithelial cells in primary cell cultures with serum-free factor-defined medium were established in a series of experiments. The cells, grown in Dulbecco's modified Eagle's medium with 0.6 mw Ca2+, epidermal growth factor, transferrin, insulin, and Na2SeO3, were fibroblast free, exhibited saturation densities similar to those of cells grown in se...
Atherosclerosis including its subclinical form is one of the key medical and social problems. At present, there is no therapy available for widespread use against subclinical atherosclerosis. The use of synthetic drugs for the prevention of arteriosclerosis in its early stages is not sufficient because of the limited indications for severe side effects and high cost of treatment. Obviously, eff...
Unscheduled DNA synthesis was observed in primary rat liver cell cultures treated with members of five different classes of chemical procarcinogens requiring enzymatic activation as well as with a direct-acting carcinogen. In total, ten carcinogens and one related analog not commonly accepted as carcinogenic were active, while one weak carcinogen and four noncarcinogens were inactive. The produ...
Primary cells are derived directly from tissue and are thought to be more representative of the physiological state of cells in vivo than established cell lines. However, primary cell cultures usually have a finite life span and need to be frequently re-established. Fibroblasts are an easily accessible source of primary cells. Here, we discuss a simple and quick experimental procedure to establ...
Neurons in primary cell cultures provide important experimental possibilities complementing or substituting those in the nervous system. However, Drosophila primary cell cultures have unfortunate limitations: they lack either a range of naturally occurring cell types, or of mature physiological properties. Here, we demonstrate a strategy which supports both aspects integrated in one culture: In...
