Depiction of intensity and molecular brightness images. (A) (Intensity) Typical single cell intensity images are shown for cells that have not been exposed to FGF9 ligand (left column) and cells exposed to 25 nM FGF9 ligand (right column). Scale bar is 15 microns. (B) (Molecular brightness) The normalized average molecular brightness images for each cell indicate monomer (red) and dimer (green) numbers and distribution throughout the cell with corresponding pixel counts, which is the number of pixels that contain dimer or monomer, respectively.
