The process that makes fireflies glow bright in the summer night can also shed light on how well new medicines work, showing immediately whether the drugs are effective at killing cells or causing other effects. That’s the conclusion of a team of scientists who report that they have inserted the gene for a firefly’s glow-producing molecule into mice with cancer, and kept it from producing its telltale beacon of light until the cells started to die in response to cancer treatment.
Scientists have found a new wrinkle in the developmental biology dogma that cell differentiation occurs irreversibly as stem cells give rise to increasingly specialized types of offspring cells. The researchers have shown that certain mouse cells retain an ability to oscillate between very distinct blood cell types ? B-cells and macrophages ? long after what has been commonly regarded as the point of no return.
