What Makes Cells Fuse?Image: Image of a microscope
Lazebnik and Duelli investigate genes and molecules in fused cells
Hypothesis: The virus might trigger cell fusion.
Hypothesis: Some of the mutations can chart a course toward cancer.
Observation #2: Fused cells develop genetic changes, or mutations.
Observation #1: Cancer-prone cells squirt out a virus that causes an AIDS-like disease in monkeys.Image: arrow
