Reporter gene expression in progenitor-derived astrocytes (PDA). The distribution of the red (early gene) and green (late gene) fluorescence of at-NCCR and rearranged CSF-1 (patient 1) rr-NCCR dual-reporter gene expression was examined in PDA cells by automated microscopy and MetaXpress software (see Materials and Methods). The histogram displays pixels carrying red and green signal distributed according to their relative signal intensity along the respective axes.
