Some determinants of cellular adhesiveness in an embryonic cell line from Drosophila melanogaster.
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 further establishes appropriate conditions for the study of cellular adhesion in Drosophila cell lines; shows that the adhesive capacity of Drosophila cell line cells, under our experimental conditions, depends upon the presence of CA2+ but not Mg2+; shows that Drosophila cell line cells will not aggregate in the cold; and shows that trypsin treatment inhibits the aggregation of cell line cells, although high concentrations of calcium ions interfere with the action of trypsin.
