FluorescenceMicroscope, Dictyostelium
This laser confocal microscopy image captures two Dictyostelium discoideum cells expressing red fluorescent protein (RFP) coexisting in a shared space. Genetically, they are identical—randomly selected from a monoclonal population of hundreds of millions, all derived from a single parent cell.
In the laboratory, such cells are industrial consumables: millions are cultured, used, killed, and discarded daily. To researchers, they are essentially interchangeable tools. However, when two specific cells from this vast collective come into contact, they escape the fate of being mere data points. This encounter allows us to observe the individuality hidden within the uniform group, and the preciousness of life emerging from the mundane.
