Activated microglia are found in a variety of neuroinflammatory disorders where they have attributed roles as effector as well as antigen-presenting cells (APC). Critical determinants for the multifaceted role of microglia are the differentiation potential of microglia and their mode of activation. In this study, we have investigated the effects...

Objective - Emerging evidence suggests that human blood contains bone marrow (BM)-derived endothelial progenitor cells that contribute to postnatal neovascularization. Clinical trials demonstrated that administration of BM-cells can enhance neovascularization. Most studies, however, used crude cell populations. Identifying the role of different...

Dendritic cells (DC) are the most potent antigen-presenting cells and are therefore useful to induce immune responses against tumor cells in patients. DC can be generated in vitro from monocytes using GM-CSF and IL-4, the so-called monocyte-derived DC (MoDC). To achieve antitumor responses, MoDC must be able to migrate to the draining lymph...

Precision-cut liver slices are frequently used to study hepatic toxicity and metabolism of xenobiotics in vitro. Successful cryopreservation techniques will enhance an efficient and economic use of scarcely available (human) liver tissue. For primary hepatocytes, slow freezing has been accepted as the best approach towards successful...

The ability of coumarin to induce UDS in male Sprague-Dawley CD rat hepatocytes in vivo was assessed using the unscheduled DNA synthesis (UDS) assay. From a preliminary toxicity study the oral maximum tolerated dose (MTD) of coumarin was determined to be 320mg/kg body weight. For the UDS studies, rats were treated with 0 (corn oil control), 32 ...

Iron absorption can be measured by the incorporation of stable iron isotopes into erythrocytes, 14 days after isotope administration. The disadvantage of this method is the high dose of isotopes needed to obtain a sufficient enrichment. Therefore, in this study cell fractions rich in young erythroid cells were prepared by using a density...

For in vitro evaluation of functional properties of endothelial cells seeded on synthetic vascular prostheses accurate and reproducible quantification of cells is mandatory. Comparison of these properties with those resulting from other studies requires correlation of the functional parameters to reliably counted cell numbers. The accuracy of...

We investigated the lobular localization and molecular level of expression of cholesterol 7α-hydroxylase and sterol 27-hydroxylase, two key enzymes in bile acid synthesis, in isolated periportal and pericentral hepatocytes and by in situ hybridization of rat liver. Enzyme activity, mRNA, and gene transcription of cholesterol 7α-hydroxylase were...

CD4+ T cells from young and aged mice were sorted into Mel-14+ cells which are regarded as naive cells and Mel-14- cells which are regarded as memory cells. These subsets were stimulated in short-time cultures with anti-CD3 or anti-CD3/anti-CD28 in order to determine the presence of Th1 and/or Th2 cytokines. Based on the simultaneous production...

The transplantable C57BL/KaLwRij mouse 5T2 multiple myeloma (MM) is a new animal model for studies on MM in man. Histological examination of the 5T2 MM cells revealed their morphological heterogeneity. In this study we investigated whether this heterogeneity reflects subpopulations of 5T2 MM cells with different biological properties. 5T2 MM...

The effect of intravenously injected endotoxin on inflammatory cells within solid Meth A tumours was studied and central hyperaemia, necrosis and early collapse were observed macroscopically at 4, 24 and 48 h, respectively. The effects were studied in semithin sections and cytocentrifuge preparations of the tumours. The inflammatory cell...

A review is presented of the experiments that resulted in the identification of a specific morphologic entity representing the pluripotential hemopoietic stem cell (HSC) in mouse bone marrow. This entity was subsequently discovered in concentrated HSC preparations from bone marrow of rats, monkeys, and humans. In the mouse, a set of physical...

Adherent cells from mouse bone marrow have been shown to promote the in vitro growth of the AVRij-1 tumour cell line. The experiments presented here suggest that the adherent cells involved in this phenomenon are the progeny of bone marrow derived fibroblastoid colony forming units. The latter were characterized by means of cell density...

Non-parenchymal cell suspensions were prepared from rat livers by three different methods based on a collagenase, a pronase and a combined collagenase-pronase treatment. The highest yield of Kupffer and endothelial cells was obtained with the pronase treatment. Attempts were made for a further purification of these cells by Metrizamide density...

A method is described for isolation of antibody forming cells with the help of cluster formation. This was achieved by incubating spleen cells from immunized mice with sheep erythrocytes at 37°C. During incubation rabbit anti mouse immunoglobulin serum was present in order to facilitate the formation of clusters. Thereafter the clusters were...
