Mast Cells and Cell-to-Cell Interactions in Airways
American Review of Respiratory Disease, 1991Dog mastocytomas (anatomic and biochemical features comparable to normal dog and human mast cells) were used to study actions of mast cell mediators on several airway effector systems. We showed mastocytoma cell adherence to both cultured tracheal epithelial cells and tracheal tissue sections for greater than 48 h that was abolished completely by ...

Biomechanics of virus-to-cell and cell-to-cell fusion
Journal of Biomedical Engineering, 1984A biomechanical model of virus-to-cell and cell-to-cell fusion is presented. Virus and the cells are modelled as initially spherical membranes of nonlinear elastic material that undergo large deformations. The membranes are connected by a cytoplasmic bridge which expands, resulting in the formation of a larger single sphere.

Gene therapy based on the use of viral vectors is entirely dependent on the use of animal cell lines, mainly of mammalian origin, but also of insect origin. As for any biotechnology product for clinical use, viral -vectors have to be produced with cells derived from an extensively characterized cell bank to maintain the appropriate standard for ...

Mechanotransduction at Cell-Matrix and Cell-Cell Contacts
Annual Review of Biomedical Engineering, 2004▪ Abstract Mechanical forces play an important role in the organization, growth, maturation, and function of living tissues. At the cellular level, many of the biological responses to external forces originate at two types of specialized microscale structures: focal adhesions that link cells to their surrounding extracellular matrix and adherens ...

Cell to substratum and cell to cell interactions of microalgae
Colloids and Surfaces B: Biointerfaces, 2013This paper reports the cell to substratum and cell to cell interactions of a diverse group of microalgae based on the Extended Derjaguin, Landau, Verwey, Overbeek (XDLVO) approach using the previously reported physico-chemical surface properties. The microalgae included 10 different species of green algae and diatoms from both freshwater and saltwater ...

A major feature in Dictyostelium development is the transition from the unicellular to the multicellular stage, a process brought about by chemotaxis and cell-cell adhesion. Growth-phase cells are weakly cohesive, whereas aggregation-competent cells adhere strongly to each other.

Cell-cell cooperation at the T helper cell/mast cell immunological synapse
Blood, 2009AbstractIt has been suggested that mast cells might serve, under certain circumstances, as antigen-presenting cells (APCs) for T cells. However, whether cognate interactions between mast cells and class II–restricted CD4+ T cells actually occur is still an open question. We addressed this question by using peritoneal cell–derived mast cells (PCMCs) and

Energetics of cell-cell and cell-biopolymer interactions
Cell Biophysics, 1989The energy vs distance balance of cell suspensions (in the presence and in the absence of extracellular biopolymer solutions) is studied, not only in the light of the classical Derjaguin-Landau-Verwey-Overbeek (DLVO) theory (which considered just the electrostatic (EL) and Lifshitz-van der Waals (LW) interactions), but also by taking electron-acceptor ...

Cell within a cell or a circulating cell pair
Nature, 1975I WISH to report that one of the coelomocytes of Phascolosoma agassizii Keferstein, 18661 (collected from Arroyo de Frijoles State Beach, California) which was previously considered to be one granulocyte is seen, under the electron microscope, to consist of two separate cells in a unique relationship.
