Abstract
Methods to present three-dimensional (3D) and time series of 3D datasets (4D) are demonstrated using the recent advances in confocal microscopy and computer visualization. The process of cell sorting during tip formation in the slime mould Dictyostelium discoideum is examined as an example by in vivo confocal microscopy of spectrally different green fluorescent protein (GFP) variants as reporters of cell-type specific gene expression. Also, cell sorting of the co-aggregating slime mould species D. discoideum and D. mucoroides is observed using a GFP variant and a spectrally distinguishable fluorescent vital stain. The confocal data are handled as 3D and 4D datasets, their processing and the advantages of different methods of visualization are discussed step by step. Selected sequences of the experiments can be viewed on the Internet, giving a much better impression of the complex cellular movements during Dictyostelium morphogenesis than printed photographs.
