background: dendritic cells (dc) induce tumor or pathogen-specific t cell responses in humans. several laboratories have developed culture systems, including maturation factors for human dc from peripheral blood monocytes. we comprehensively compared standard maturation stimulus, an autologous monocyte-conditioned medium (mcm), with heparin for their ability to promote uniformly mature dc that ...

predominantly antibody deficiencies are a category of primary immunodeficiency diseases, which consist of several rare disorders such as common variable immunodeficiency (cvid) and x-linked agammaglobulinemia (xla). we evaluated the effects of cvid and xla patients’ sera as a source of microenviromental factors on maturation and function of monocyte-derived dcs. blood was collected from 10 cvid...

BACKGROUND Endothelial dysfunction initiated by monocyte-endothelial interactions has previously been observed in many vasculopathies, including chronic cigarette smoking. Taurine, a semiessential amino acid, and vitamin C, a naturally occurring antioxidant, have previously been shown to have endothelial protective effects when exposed to proinflammatory insults. Therefore, we hypothesized that...

To investigate the effects of the conditioned medium on regulation of hematopoietic stem cells, serial volumes of monocyte-conditioned medium were added to the culture systems of CFUE and CFUC. Small volumes of the conditioned medium possessed stimulatory activity and large volumes inhibitory activity for both CFUE and CFUC. These findings suggest that the monocyte-conditioned medium regulates ...

Stimulators of human erythroid burst-forming units (BFU-E) and multipotential colony-forming cells (CFU-GEMM) can be produced by a number of different cell types. A product of human peripheral blood monocytes, interleukin 1 (IL-1), was evaluated for its ability to stimulate fibroblast cultures to produce stimulators of human bone marrow BFU-E and CFU-GEMM colony formation. BFU-E and CFU-GEMM co...

Tissue engineering strategies rely on the ability to promote cell proliferation and migration into porous biomaterial constructs, as well as to support specific phenotypic states of the cells in vitro. The present study investigated the use of released factors from monocytes and their derived macrophages (MDM) and the mechanism by which they regulate vascular smooth muscle cell (VSMC) response ...

Background: Generation of an effective dendritic cell (DC) based cancer vaccine depends on appropriate differentiation of monocytes in vitro. Objective: To compare the effects of monocyte separation methods, flask adherence (Flask-DC) and magnetic activated cell sorting (MACS-DC), on phenotypic and functional characteristics of resultant DCs. Methods: DCs from healthy volunteers were generated ...
