Abstract
The effectiveness of granulocyte colony-stimulating factor (G-CSF) for granulocytopenia has been widely recognized. However, although granulocyte counts rapidly increase after a few injection of G-CSF, a large proportion of the increased granulocytes disappear from peripheral blood within a few days following G-CSF withdrawal. Where do they go? In this report, the answer can be seen at a glance. Using MitoCapture and a CCD camera-equipped fluorescence microscope, we succeeded in demonstrating that G-CSF withdrawal induced loss of mitochondrial membrane potential, i.e., an early stage of apoptosis, in human peripheral granulocytes increased by G-CSF.
