Abstract
We have examined, under a number of conditions, the aggregation behavior of Schneider Line 2 cells established originally from embryos of Drosophila melanogaster. The work presented in this paper 1) further establishes appropriate conditions for the study of cellular adhesion in Drosophila cell lines; 2) shows that the adhesive capacity of Drosophila cell line cells, under our experimental conditions, depends upon the presence of CA2+ but not Mg2+; 3) shows that Drosophila cell line cells will not aggregate in the cold; and 4) shows that trypsin treatment inhibits the aggregation of cell line cells, although high concentrations of calcium ions interfere with the action of trypsin.
