Co-cultures of multiple cell types mimic pulmonary cell communication in response to urban PM10

Co-cultures of multiple cell types mimic pulmonary cell communication in response to urban PM10.

The current authors evaluated whether a system of co-cultures of relevant cells (pneumocytes (A549), macrophages (THP-1), mast cells (HMC-1) and endothelial cells (EAHY926)) would mimic the responses to particles with a 50% cut-off aerodynamic diameter of 10 microm (PM(10)) previously reported in vivo. The role of mast cells was considered of special interest. Single cultures, bicultures (A549 ...

Immune response of chickens to four lentogenic strains of Newcastle disease virus propagated in lamb kidney cell cultures

Studying cell-cell communication in co-culture.

The formation, maintenance, and repair of biological tissues rely on the interaction of cells with other cell types and with their extracellular matrix [2, 3]. These cellular communications can be bi-directional or multi-dimensional and may occur at both macroand micro-scales. Depending on the hypothesis of interest, co-culture models are used to discern the individual and collective effects of...

Response of cell cultures to asbestos fibers

The reaction of macrophages to asbestos and glass fibers was studied by light and by electron microscopy. Measurements were made of LDH release, staining with erythrosine B, and lactate production. Size and shape of asbestos fibers were found to have more effect than the physicochemical properties of the surface. Long fibers resulted in a protracted pathogenic but no acute cytotoxic effect.

Isolation and Identification of Yeast Strains Capable of Producing Single Cell Protein from Whey in Co-Cultures with Saccharomyces cerevisiae

In this study, twenty-five whey samples collected from dairy industries in the city of Isfahan. The sampleswere cultured on malt extract broth (MEB) and yeast extract glucose chloramphenicol agar (YGCA) media.Eleven yeast strains (designated M1 to M11) were isolated from the culture. The strains were identified bytheir morphological and physiological properties. Betagalactosid...
