Analysis of optical density wave propagation and cell movement in the cellular slime mould Dictyostelium discoideum
We have studied optical density wave propagation during aggregation of the cellular slime mould Dictyostelium discoideum in a quantitative manner by digital image analysis. The waves arc mostly single ended spiral waves starting from an aggregation center. We can measure a variety of parameters such as oscillation frequency, wave propagation velocity and wave shape. This allows the construction...
متن کاملThe isolation and subfractionation of plasma membrane from the cellular slime mould Dictyostelium discoideum.
A procedure for the isolation and separation of three different subfractions of plasma membrane from the cellular slime mould Dictyostelium discoideum is described. The cells were disrupted by freeze-thawing in liquid N(2) and plasma membranes were purified by equilibrium centrifugation in a sucrose gradient. The cell surface was labelled with radioactive iodide by using the lactoperoxidase iod...
متن کاملEffect of temperature on the mutual adhesion of preaggregation cells of the slime mould, Dictyostelium discoideum.
The mutual adhesion of slime-mould cells was investigated at 24 and 1 °C in stirred and unstirred medium. Adhesion was induced by adding sodium chloride and followed by recording the diminution in optical density of the cell suspension associated with the formation of cell aggregates. It was found that: (1) when cells, previously stored at 1 °C, were stirred in distilled water at 24 C the optic...

متن کاملMotive force of the migrating pseudoplasmodium of the cellular slime mould Dictyostelium discoideum.
Motive forces of migrating pseudoplasmodia (slugs) of Dictyostelium discoideum were determined by application of a double-chamber method. The motive force of a whole slug was proportional to its volume, the value per unit volume being 5.85 x 10(-6) dyne/cm3 (58.5 N cm-3). The motive force was independent of temperature (13.5--26 degrees C) and decreased during prolonged migration. Motive force ...
